• How to build a private Wi-Fi Network server with VMware?

  - by Maarten Schermer

  For a school project, we have to build a Private network with VMware vSphere , which we can connect to with a Username and Password. On the network we want to create a folder for each Useraccount. Also we must have add a few groups (Admin,Customer,Manager). We must be able to connect to our network via the school Wi-Fi. We want to build a safe and secure network, with an easy way to access the network. Do you have any tips on how to approach this?

• Trying to communicate between virtual servers on the same host through ipv6

  - by Daniele Testa

  I am running KVM on a host with 2 virtual servers. Each virtual server has a own bridge interface on the host VPS1 has br1 VPS2 has br2 Each virtual server has a own ipv4 and a ipv6. The virtual servers has no problem communicating with internet or with eachother through ipv4. However, with ipv6, they can only communicate with internet and NOT with eachother. The host can ping the 2 virtual servers without any problems, but they cannot ping eachother. iptables has been set to ACCEPT on all chains, so it is not the problem. VPS1 has ipv6 = 2a01:4f8:xxx:xxx::10 VPS2 has ipv6 = 2a01:4f8:xxx:xxx::5 the host has the following routes set: ip route add 2a01:4f8:xxx:xxx::10 dev br1 ip route add 2a01:4f8:xxx:xxx::5 dev br2 When I do a ping from VPS2 to VPS1, I see the following on the host: tcpdump -i br1 15:32:27.704404 IP6 2a01:4f8:xxx:xxx::10 > ff02::1:ff00:5: ICMP6, neighbor solicitation, who has 2a01:4f8:xxx:xxx::5, length 32 So it seems like the host is seeing the request coming from VPS1 on br1. But for some reason, it does not forward it to br2. Instead it is asking where the destination IP is through ipv6 multicast. Anyone has a clue what is going on? I find this very strange, as it is working fine with ipv4 with the exact same settings and routes.

• WinXP workgroup, 3 routers 3 computers

  - by Silvera

  I have 3 computers with WinXP x86, and 3 Cisco 1800 series routers. I'm trying to create a workgroup so that the 3 computers can share files with eachother. They can ping eachother (without any internet connection), and the routers setup is correctly configured (with interfaces, ip adresses, and ports). But none of the computers can see eachother, even though they are on the same network. My first question would be - can it be done the way it is currently configured - and, if yes, how, or can anyone point me in the right direction?

• Can I connect two routers to one switch?

  - by vanneto

  I want to connect two routers to a switch which will then be connected to a modem. Now as far as I know a switch does not do network translation and this won't work with one IP address. So I bought two addresses at my ISP. Attached is a simple schematic that explains what I want to do. Is there any additional configuration needed on either of the routers (Linksys WRT54GL) to make this work or will it "Just Work"?

• Redirect traffic to local address so iOS speedtest app measures LAN speed

  - by ivan_sig

  I have mounted a Speedtest Mini server on a local LAMP, so I can test my LAN speeds effortlessly just by opening the URL with a Flash enabled web browser, the thing is, I want my iOS and Android devices to test with the LAN server too, not with the WAN, as I'm trying to measure LAN-Only performance. Is there a way so I can redirect the traffic intended to an specific external IP (The one of the real server) to my local server?. I know the servers IP as a short Wireshark analysis gave me the data, but still searching for a way to make that redirect. I have Jailbreak and root on my devices, so playing with system files is not a problem. I've tried mounting a proxy and making redirects by the hosts file and domain names, but it looks like Ookla's app relies on IP address only.

• Cablemodem (SBG6580) firewall denying some outbound traffic? Why? Not configured [migrated]

  - by lairdb

  I finally got around to turning the syslog on for my cablemodem (Motorola Surfboard SBG6580) and I'm seeing about the expected amount of inbound attackage being blocked... 2014-05-30 21:59:02 Local0.Alert 192.168.111.1 May 31 04:58:56 2014 SYSLOG[0]: [Host 192.168.111.1] UDP 12.230.209.198,4500 --> 66.27.xx.xx,61459 DENY:Firewall interface [IP Fragmented Packet] attack 2014-05-30 21:59:02 Local0.Alert 192.168.111.1 May 31 04:58:56 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 17.172.232.109,5223 --> 66.27.xx.xx,53814 DENY:Firewall interface access request 2014-05-30 21:59:02 Local0.Alert 192.168.111.1 May 31 04:58:57 2014 SYSLOG[0]: [Host 192.168.111.1] UDP 12.230.209.198,443 --> 66.27.xx.xx,53385 DENY: Firewall interface [IP Fragmented Packet] attack 2014-05-30 21:59:02 Local0.Alert 192.168.111.1 May 31 04:58:57 2014 SYSLOG[0]: [Host 192.168.111.1] UDP 12.230.209.198,4500 --> 66.27.xx.xx,61459 DENY:Firewall interface [IP Fragmented Packet] attack 2014-05-30 21:59:10 Local0.Alert 192.168.111.1 May 31 04:59:04 2014 SYSLOG[0]: [Host 192.168.111.1] UDP 12.230.209.198,443 --> 66.27.xx.xx,59960 DENY: Firewall interface [IP Fragmented Packet] attack 2014-05-30 21:59:10 Local0.Alert 192.168.111.1 May 31 04:59:04 2014 SYSLOG[0]: [Host 192.168.111.1] UDP 12.230.209.198,4500 --> 66.27.xx.xx,61459 DENY:Firewall interface [IP Fragmented Packet] attack ...and that's great. (Sad, but great.) But I'm also seeing a HUGE amount of what appears to be denied outbound connectivity: 2014-05-30 16:30:10 Local0.Alert 192.168.111.1 May 30 23:30:04 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 192.168.111.100,58969 --> 38.81.66.127,443 DENY: Inbound or outbound access request 2014-05-30 16:30:10 Local0.Alert 192.168.111.1 May 30 23:30:04 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 192.168.111.100,58969 --> 38.81.66.127,443 DENY: Inbound or outbound access request 2014-05-30 16:30:10 Local0.Alert 192.168.111.1 May 30 23:30:04 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 192.168.111.100,58965 --> 162.222.41.13,443 DENY: Inbound or outbound access request 2014-05-30 16:30:10 Local0.Alert 192.168.111.1 May 30 23:30:04 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 192.168.111.100,58965 --> 162.222.41.13,443 DENY: Inbound or outbound access request 2014-05-30 16:30:10 Local0.Alert 192.168.111.1 May 30 23:30:04 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 192.168.111.100,58964 --> 38.81.66.179,443 DENY: Inbound or outbound access request 2014-05-30 16:30:10 Local0.Alert 192.168.111.1 May 30 23:30:04 2014 SYSLOG[0]: [Host 192.168.111.1] TCP 192.168.111.100,58964 --> 38.81.66.179,443 DENY: Inbound or outbound access request ...and Spot checking suggests that it's all legitimate traffic (Opening connections to CrashPlan, etc.), I have no restrictions configured in the modem; I don't see why it should be blocking anything. Am I misreading the log entry, and it's not actually being denied? (Seems unlikely.) Is the ISP (TWC) pushing deny tables that are not exposed in the UI? (Tinfoil hat too tight.) I'm confused. (The good news, such as it is, is that AFAIK I'm not experiencing any actual issues... but maybe I am; tough to tell.) Thanks.

• Stopped windows firewall service during ICS, how is this possible?

  - by insipid

  Although windows firewall is required to be on when you "start" Internet Connection Sharing, you can stop the WF service with MMC. When done a client can still use the host machines internet. The firewall had port 80/http blocked, and now it is open for incoming traffic. However other ports used by applications on the host and client which communicate with each other still seem to be blocked. Can anybody explain what might be happening here? Doesn't ICS need windows firewall for NAT? Note: I am not actually seeing anything in the firewall logs after stopping the service, but even packets sent localhost on the host machine never arriving on these other random ports.

• Lenovo Mini Wireless Keyboard N5901: Remap orange "My Computer" button

  - by Jon Schneider

  I have a Lenovo Mini Wireless Keyboard N5901 (a.k.a. Part No. 57Y6336) that I'm using with an HTPC running Windows 7. The remote comes with an orange button in the top-left corner that by default, when pressed, opens the Windows "My Computer" window. I would like to remap / reprogram this button to act like the green "Windows Media Center" button instead on a Windows Media Center (WMC) remote; that is, open Windows Media Center if it isn't already open, or go to the WMC homepage if WMC is already open. I've tried several keyboard-remapping utilities (as recommended in other, more general "how to remap keyboard key?" SuperUser.com questions) including SharpKeys, Key Mapper, and KeyTweak, with no luck so far. None of these utilities recognize the orange button -- they all do recognize that some key was pressed, but display a value for the key of "unsupported" or something similar. I was able to use a utility called Keyboard Scan Code Generator to determine that a press of the orange button has a KeyData value of 16777217 (0x1000001), and a "Virtual Code" value of 182. (The other "media" buttons on the N5901 have the same KeyData value, but different Virtual Code values). I'm not sure at this point where in Windows this keystroke is being interpreted as a command to open "My Computer." There is no special software / driver for this device; it worked out of the box with Windows 7, no special driver install necessary. Is there any way to accomplish this? Thanks in advance for any suggestions!

• Unable to Use Bluetooth Mighty Mouse or Wireless Keyboard with Boot Camp

  - by Kristopher Johnson

  I have Windows 7 64-bit running on a MacBook Pro in a Boot Camp partition. I am trying to pair with my Bluetooth Mighty Mouse and Apple wireless keyboard under Windows, but whenever I try to do so, here's what happens: While on the Add a device window, I turn on the mouse or press a key on the keyboard, and the mouse or keyboard shows up in the list of available devices. I click the device and then the Next button, and the window displays Connecting to device... Time passes. Eventually, I get this error message: Adding this device to this computer failed Adding the device failed resulting in an unknown error. The reported error code is 0x80070015. Contact your device manufacturer for assistance. I've run Windows Update and Apple Software Update. I've also tried reinstalling the drivers from the Snow Leopard DVD. The mouse and keyboard both work fine when I boot into Mac OS X. FWIW, after many, many repeated tries, I eventually got it to work. I don't know why. So while my problem is solved, I'd still like to get an "answer" as to why trial-and-error seems to be the only approach. The keyboard, in particular, was hard to get set up. A few times, Windows would apparently recognize it and prompt me to enter the pairing code, but then it would time out after a couple of seconds (not long enough to enter the code). Grrrr.

• Ubuntu - wireless connection works great but wired is totally dead

  - by Dan

  I am running Ubuntu 10.04 on my Acer Aspire One netbook. The wireless connection works great, but the wired is totally dead. When I plug the Ethernet wire, the little led next to the port doesn't blink. If I do ifconfig, this is the output: lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1659 errors:0 dropped:0 overruns:0 frame:0 TX packets:1659 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:132304 (132.3 KB) TX bytes:132304 (132.3 KB) wlan0 Link encap:Ethernet HWaddr 18:f4:6a:65:48:1f inet addr:192.168.1.7 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::1af4:6aff:fe65:481f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:94823 errors:0 dropped:0 overruns:0 frame:0 TX packets:81390 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:93028474 (93.0 MB) TX bytes:18002558 (18.0 MB) There is no eth0.

• Transfer VLAN tagged packets over WLAN?

  - by stefan.at.wpf

  I have the following composition of devices: [selfmade router] - ethernet - [WLAN router 1] ----- wlan ------ [WLAN router 2] WLAN router 2 has 5 ethernet ports, each as an own VLAN, so 5 VLANs. I want to manage the routing and firewalling between those VLANs at selfmade router. What technique would I use to pass the tagged vlan packets from WLAN router 2 to selfmade router? Could I use a bridge from WLAN router 2 to WLAN router 1 which itself has a bridge from WLAN router 1 to selfmade router or do I have a wrong understanding of a bridge? Thanks for any hint on this :-)

• How to bypass firewall to connect to a proxy server?

  - by Bruce

  I am conducting a small experiment on my office network. I have setup a proxy server on my desktop machine (connected to my LAN) and I have volunteers access the internet via my proxy server. Everything is working well. The problem is people cannot connect to the proxy server through their laptops. I asked my network admin and he said the wireless network has a firewall which prevents users from connecting to my proxy. He said I could tunnel the traffic or use SSH though. I am afraid I do not understand fully what is going on. Is there a way by which users connected on the wireless network can connect to my desktop? I am using FreeProxy on Windows as my proxy server: http://www.handcraftedsoftware.org/index.php?page=download FreeProxy allows me to create a SOCKS 4/4a/5 proxy. Is that what I need? Part of the experiment involves logging the URL requests of the users. I am doing a measurement study. So, any solution must allow me to log the URL requests of users. Also, what changes do I need to make in the browser configuration.

• Looking for software to create a personal hotspot on Mac OS X (not using the built-in ability)

  - by Fred

  I got my nifty little MacBook Air today. Since I will be going on travel I was hoping to use my iPad 3G as screen extension with Air Display. It works being in a shared WiFi network. Sadly Apple is a bit restrictive on the tethering with their mobile devices such as the iPad. Now I read iOS 4.3 will enable the iPad to use tethered networks. But the feature will not be working for iPad 3G. I assume their big partner telecom companies fear everyone will quit their internet contract with them. So I want to create a personal hotspot on my MacBook and use it on my iPad. But the iPad is not able to use this network. The network is visible but not usable. On Windows there is this connectify program which lets the PC act as wireless router. Does anybody know a similar program for Mac which would turn it into a wireless router? Or is there something I don't see with Mac OS X's builtin features?

• Computer causing WiFi interference?

  - by Mannimarco

  I came back from college and brought my desktop computer. Family recently switched to Verizon FIOS and got a new router because of it. Unfortunately, my connection to the new wifi network is awful, with the download speeds (tested through speedtest.net) fluctuating wildly and often dropping below 1.5 Mbps. A laptop in the same room gets 20 Mbps. I've tried a new wireless card, thinking that mine got damaged in the move home but no luck. Here's where it gets weird: if I place the laptop near the computer, the laptop's download speeds often suffer greatly. Pulling the laptop away always fixes this. So now I'm under the impression that there's something in the computer (which I built a year ago and has had 0 issues up to this point) is causing an insane amount of wireless interference. Also bizarre: the upload speeds seem unaffected by this problem. On the laptop and desktop, upload speeds are generally around 5 Mpbs. Any ideas as to what could be causing this and how to test said theories would be fantastic.

• Setup for a live (low-latency) audio video broadcast over Wi-Fi?

  - by Majal Mirasol

  The Upgrade We are capturing audio (from mixer) and video (from a camera) from a main auditorium and passing it to separate rooms within the building. We used to have done this via manual audio/video cables and wires. We wanted to "upgrade" the system and wirelessly broadcast the stream via Wi-Fi. The Problem In our current setup (Wirecast running on A10 on a Wireless-N network), we have the problem of delay. Our streams are delayed from a minute up to five minutes on the clients (laptop/iPad/Android). This had not been a problem from the previous wired connections. Since the wireless network is local, we thought that a delay of less than a second should be achievable. Our Question And so it goes. Anybody there who has any experience for a setup that has both low latency and at the same time user-friendly to clients streaming in the program? Any recommendations would be highly appreciated. (Our current setup in on Windows 7, but setup on a dedicated Linux box is preferred, if achievable.)

• Port Forwarding(?) TD-W8961nd

  - by rich

  I have a bit of a weird internet setup. I am connected via a decent WiFi connection (from work) which I pick up using a Buffalo Airstation Wireless-G box. This simply picks up the signal and gives me 4 ethernet ports to connect to. That's all fine and works as it should. I also have a TP LINK TD-W8961nd router which used to be connected to the Airstation via an ethernet cable so I could essentially have WiFi access in my house. To cut a long story short I can't remember how the hell I got it to work and I can't find the notes I scribbled down on how to do it. I'm pretty sure I need to tell the router what ip to pick up the internet connection from and have the local wifi as a seperate network. How the hell I do that I have no idea right now. Can anyone give me some advice on this? If you need more information ask and I will be able to do so. Cheers in advance. edit I'm in work at the moment so I can't give 100% details but I will be able to later on.

• How to pipe internet radio into a tuner?

  - by JW

  UPDATE: Thanks everyone for the ideas! This was an area I knew very little about but now I can talk with a little more expertise about it. Much appreciated! Visited my dad this weekend and he wants to pipe some internet radio he's found down to a tuner on quite a distance away in the house. He uses computers for only very basic things: e-mail, getting the Post crossword, checking Yahoo!, checking recipes, etc. There's currently one computer in the house (no router). My initial suggestion (without any research whatsoever) was to get a wireless router and a netbook for downstairs near the tuner, but he initially wasn't too keen about having another computer down there. Anyway, is there any computer hardware that could magically pipe the audio output from the computer down to one set of (RCA) audio inputs on the tuner? Wireless isn't necessary but it probably would be easier. Anyway, thanks for your suggestions! UPDATE Thanks everyone! Voted up all of your suggestions now that I have 15 rep. Much appreciated.

• Why does my DSL modem now need a reboot each time for my laptop to connect?

  - by msorens

  I have a rather peculiar home networking issue. For sometime my home network was purring along fine. I could turn on either of my laptops and they would quickly find and connect to my DSL modem (and thence the internet). Several days ago I unplugged my DSL modem for the first time in months. Upon turning it back on and waiting for the boot to finish, the lights on the panel indicated the DSL modem was fully operational, just as before. But that's not what happened. Not at all. Now when I turn on my Win7 laptop, the network icon in my system tray shows a small starburst; hovering over it the tooltip states "Not connected; connections are available". Clicking it lists several nearby networks including my own network showing a strong signal. If I click to connect, it attempts a connection but then I get a dialog stating "Windows was unable to connect to MyNet.". Turning off wireless on my laptop and turning it back on yields no difference. Running the network troubleshooter (which includes doing a repair on the network connection) yields no difference. The only remedy is to reboot the DSL modem (i.e. unplug it, wait a few seconds, then plug it back in). As soon as it goes online my laptop finds it and connects properly. To add one more twist to the story, this happened to me once before, several months ago. After a couple weeks, the situation resolved itself(!). Everything started working properly again, due to nothing I did. Final note: this problem only affects the wireless connection to the DSL modem. My desktop computer, connected via hardline to the DSL modem, connects fine when I turn it on. Any thoughts on why this is happening or how to fix it?

• After connecting wlan0 to bridge interface (and then removing it), can't connect to AP

  - by gmonk

  I'm on a laptop running Debian Jessie with kernel 3.13-1-amd64; lspci shows that my wireless NIC + driver is 04:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) Subsystem: Intel Corporation Dual Band Wireless-AC 3160 Kernel driver in use: iwlwifi This has been working without any problems, until I tried creating a bridge for lxc containers to use. I did the same thing as this person here: How-to set up a network bridge on a laptop for LXC use? -- and ended up having the same problem as this poster did, so I decided to "undo" my actions. This hasn't been successful. Actions taken so far: To configure the bridge: #> ip link add type veth #> iw dev wlan0 set 4addr on #> ifconfig veth0 up #> brctl addbr br0 #> brctl addif br0 wlan0 #> brctl addif br0 veth0 #> ifconfig br0 192.168.0.4/24 #> ifconfig wlan0 0.0.0.0 To "deconfigure": #> brctl delif br0 wlan0 #> brctl delif br0 veth0 #> iw dev wlan0 set 4addr off #> ifconfig veth0 down #> ifconfig wlan0 down #> ifconfig br0 down #> brctl delbr br0 Now, dmesg and /var/log/syslog show repeated attempts at connecting to the AP that was working before, which fail after authentication: May 27 09:16:01 myhostname kernel: [11350.757172] wlan0: authenticate with 00:18:f8:54:a3:d6 May 27 09:16:01 myhostname kernel: [11350.759036] wlan0: send auth to 00:18:f8:54:a3:d6 (try 1/3) May 27 09:16:01 myhostname NetworkManager[13992]: <info> (wlan0): supplicant interface state: scanning -> authenticating May 27 09:16:01 myhostname wpa_supplicant[8946]: wlan0: Trying to associate with 00:18:f8:54:a3:d6 (SSID='myaccesspoint' freq=2437 MHz) May 27 09:16:01 myhostname kernel: [11350.762615] wlan0: authenticated May 27 09:16:01 myhostname kernel: [11350.762753] iwlwifi 0000:04:00.0 wlan0: disabling HT as WMM/QoS is not supported by the AP May 27 09:16:01 myhostname kernel: [11350.762755] iwlwifi 0000:04:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the AP May 27 09:16:01 myhostname kernel: [11350.765080] wlan0: associate with 00:18:f8:54:a3:d6 (try 1/3) May 27 09:16:01 myhostname NetworkManager[13992]: <info> (wlan0): supplicant interface state: authenticating -> associating May 27 09:16:01 myhostname kernel: [11350.767474] wlan0: RX AssocResp from 00:18:f8:54:a3:d6 (capab=0x411 status=12 aid=0) May 27 09:16:01 myhostname kernel: [11350.767476] wlan0: 00:18:f8:54:a3:d6 denied association (code=12) May 27 09:16:01 myhostname wpa_supplicant[8946]: wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:18:f8:54:a3:d6 status_code=12 May 27 09:16:01 myhostname kernel: [11350.788475] wlan0: deauthenticating from 00:18:f8:54:a3:d6 by local choice (reason=3) May 27 09:16:01 myhostname NetworkManager[13992]: <info> (wlan0): supplicant interface state: associating -> disconnected May 27 09:16:01 myhostname NetworkManager[13992]: <info> (wlan0): supplicant interface state: disconnected -> scanning May 27 09:16:02 myhostname dhclient: DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 14 May 27 09:16:04 myhostname wpa_supplicant[8946]: wlan0: SME: Trying to authenticate with 00:18:f8:54:a3:d6 (SSID='myaccesspoint' freq=2437 MHz) May 27 09:16:04 myhostname kernel: [11354.559579] wlan0: authenticate with 00:18:f8:54:a3:d6 May 27 09:16:04 myhostname kernel: [11354.561458] wlan0: send auth to 00:18:f8:54:a3:d6 (try 1/3) May 27 09:16:04 myhostname wpa_supplicant[8946]: wlan0: Trying to associate with 00:18:f8:54:a3:d6 (SSID='myaccesspoint' freq=2437 MHz) May 27 09:16:04 myhostname NetworkManager[13992]: <info> (wlan0): supplicant interface state: scanning -> associating May 27 09:16:04 myhostname kernel: [11354.563445] wlan0: authenticated May 27 09:16:04 myhostname kernel: [11354.563631] iwlwifi 0000:04:00.0 wlan0: disabling HT as WMM/QoS is not supported by the AP May 27 09:16:04 myhostname kernel: [11354.563633] iwlwifi 0000:04:00.0 wlan0: disabling VHT as WMM/QoS is not supported by the AP May 27 09:16:04 myhostname kernel: [11354.565727] wlan0: associate with 00:18:f8:54:a3:d6 (try 1/3) May 27 09:16:04 myhostname wpa_supplicant[8946]: wlan0: Associated with 00:18:f8:54:a3:d6 May 27 09:16:04 myhostname kernel: [11354.568091] wlan0: RX AssocResp from 00:18:f8:54:a3:d6 (capab=0x411 status=0 aid=9) May 27 09:16:04 myhostname kernel: [11354.569030] wlan0: associated May 27 09:16:04 myhostname NetworkManager[13992]: <info> (wlan0): supplicant interface state: associating -> associated May 27 09:16:05 myhostname kernel: [11354.978204] wlan0: deauthenticated from 00:18:f8:54:a3:d6 (Reason: 15) May 27 09:16:05 myhostname wpa_supplicant[8946]: wlan0: CTRL-EVENT-DISCONNECTED bssid=00:18:f8:54:a3:d6 reason=15 May 27 09:16:05 myhostname kernel: [11354.992729] cfg80211: Calling CRDA to update world regulatory domain May 27 09:16:05 myhostname kernel: [11354.995004] cfg80211: World regulatory domain updated: May 27 09:16:05 myhostname kernel: [11354.995005] cfg80211: (start_freq -

I'm not sure what I did wrong, or what step I've skipped in trying to get wlan0 back as a non-bridged device -- I removed it from the bridge and then deleted the bridge itself. Any ideas?

• 802.11g -> wired ethernet bridging not working

  - by Malachi

  Usually people want to go the other direction, but I want to take our relatively fast and stable house 802.11g signal and bridge it to ethernet. I have tried using an Airport Express (the b/g flavor) and my i7 MacBook pro, both to no avail. Word is that the b/g flavor of This flavor of Airport Express maxes at firmware 6.3 which doesn't support this kind of bridging properly. However, I expected my MacBook pro to do the job with its "Internet Sharing" feature. Alas, although my wired PC does sort of see it, it doesn't work out. Strangely, using DHCP the PC receives the same IP address as my MBP uses on the network. Less strangely, but still surprisingly, the wired ethernet port on my mac registers as the IP address of the gateway when queried with IFCONFIG. It sort of makes sense that the mac would "pretend" to be the gateway, but the whole thing just isn't working and seems configured wrong - but all the docs I see say basically "OS X Internet Sharing: click it and go". What do I do? Do i really have to buy more hardware, even though I have plenty of would-be candidates for bridging? Incidentally, the host router originating the 802.11g signal is a belkin 802.11g router, and is documented to support WDS.

• Lion MacBook Pro will not load webpages with DNS just after wake

  - by NReilingh

  I'm working with a 2011 MacBook Pro running Lion (10.7.2), that after waking from sleep (i.e. opening the lid) takes an inordinately long amount of time (2-3 minutes or more) to get a usable internet connection. Upon waking, the wi-fi icon signifies it is negotiating a network connection, and completes one a few seconds later. At this point, network diagnostics will not show any issues, and everything in Network preferences looks as normal: I'm connected to the proper network, have the right IP address and gateway, and DNS settings are correct. However, any site accessed with a domain name (like http://www.google.com) in Safari will return the "You are not connected to the Internet." error. Accessing a site directly, say, with Google's 74.125.226.212, is successful. Yet, Network Diagnostics will insist that DNS is functioning properly. After a few minutes, the following lines will be printed to the Console log, and regular behavior will be restored. 11/18/11 8:11:31.288 PM airportd: _doAutoJoin: Already associated to “Wireless”. Bailing on auto-join. 11/18/11 8:11:32.000 PM kernel: en1: BSSID changed to 00:25:9c:63:91:bd This behavior occurs only when waking from sleep--not when turning wi-fi on and off. This problem also occurs when using a wired Ethernet connection. As per this thread, I have tried flushing the DNS cache and wiping the wireless network from memory (it's not a protected network). Neither have worked.

• Network switches for LAN party

  - by guywhoneedsahand

  I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

• Wi-Fi won't automatically connect (box in Windows configuration gets unchecked)

  - by greg88

  The checkbox that says "Use windows to configure my wireless network settings" keeps getting unchecked (Wirless Network Connection - Change advanced settings - Wireless networks tab.) How do I stop that from happening? (So the wi-fi will reconnect.) When I manually re-check the box, it automatically connects.) I have a D-Link AirPremier DWL-G550 PCI adapter. I installed the newest driver, 5.3.0.46, and that didn't solve the problem. I took the "Atheros Client Utility" (the program window says "D-Link AirPremier Client Utility" when you run it) out of the start menu, rebooted, and that didn't solve the problem. (That utility puts a signal bar similiar to the one MS Windows puts there, and it's gone now.) The D-Link client utility has an option to automatically connect to preferred networks, but it is greyed out. It is also greyed out if I install the driver and utility right off the D-Link installation CD, so the problem isn't that the utility and driver are incompatible versions. I want to use Windows to handle the connection anyway, as the D-Link utility is garbage. Windows XP SP3 w/all current updates.

• MacMini transmit rate stuck at 11, every other device can connect at full 54Mbit/s?

  - by chum of chance

  I have a MacMini circa 2007 that's getting very low transmit rates via wifi, 8-11. I have other devices that are getting full 54, including a MacBook Air. With everything else off, the MacMini doesn't want to seem to go any faster. Since it has been previously connected to ethernet its entire life, I was wondering if there were some settings I can change to speed up the connection. Option-clicking the network icon gives this read out: PHY Mode: 802.11g Channel: 1 (2.4 Ghz) Security: WPA2 Personal RSSI: -73 Transmit Rate: 11 My new MacBook Air has the following readout: PHY Mode: 802.11n Channel: 1 (2.4 Ghz) Security: WPA2 Personal RSSI: -66 Transmit Rate: 79 Both have full bars and the wireless router is in the same room to eliminate any obstructions from the equation. Could the MacMini be connecting at an older protocol, like 802.11b and be reporting erroneously that it is connected at 802.11g? This would explain why I haven't seen a transmit rate above 11. Any further trouble shooting I can try before buying a new USB 802.11n device? The WiFi router is a DLink DIR-615. I can see other devices, and none, even the other g connected devices, are getting below 30-40 MBit/s. What's going on here?
