• Dell Latitude E6400 power button and wireless not working or only working intermittently

  - by Droid

  The power button on the laptop stopped working randomly as of a day or two ago. I can only power the laptop on if its attached to a docking station, on which I can use the power button to turn on/off the laptop. Today the wireless card stopped working (the wifi light does not turn on, even after I turn on the wireless switch). What is the problem and how can I fix it? The laptop is about 1 year old. I have not dropped it, but do carry it around a good amount, including docking it/undocking it frequently.

• set tap0 using virt-manager for bridged wireless

  - by DaveO

  After 3 days I finally have kvm guests working on the network via wireless (link below - thanks!): My network is 192.168.1.0/24 on the host: sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward" sudo tunctl -t tap0 sudo ip link set tap0 up sudo ip addr add 192.168.1.25/24 dev tap0 sudo route add -host 192.168.1.30 dev tap0 sudo parprouted wlan0 tap0 on the guest: auto eth0 iface eth0 inet static address 192.168.1.30 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.25 and start the guest: sudo kvm /path/to/guest.img -net nic,macaddr=DE:AD:BE:EF:90:26 -net tap,ifname=tap0,script=no This works great and I can ping the local network and the internet back and forth between the guest. But how do I add these settings to the guest's xml config so I can start the guest via virt-manager with the same nic settings? ref: http://www.linuxquestions.org/questions/debian-26/kvm-wireless-bridge-network-691953/

• Setting a wireless access point on Ubuntu server 11.10

  - by Solignis

  I am trying to setup a wifi access point with my Ubuntu server. I have managed to get my phone to connect the wireless and now it get a DHCP lease. Though it still cannot ping out or get pinged by anything on my network. I am prety sure my problem is iptables, but I not sure what would be wrong. Here is what my rules look like. (The ones pertaining to the bridge interface) # Allow traffic to / from wireless bridge interface iptables -A INPUT -i br0 -j ACCEPT iptables -A OUTPUT -o br0 -j ACCEPT I am guessing my rules are a little lean, the bridge exists on the same subnet as everything else on my network, I am using a 10.0.0.0/24 subnet. EDIT Oh yeah I should mention also, when I do a ping test, I get Destination Host Unreachable as the error.

• I have a wireless Canon P560 and my computer can't find it

  - by ed

  The printer is wireless and I haven't connected it via USB. I set the configurations for the Wi-Fi access point in the printer and it connected to my Wi-Fi. I have AT&T as the service provider and the 2Wire router. When I access the router in the browser I see that the printer is connected but when I run the software to detect the printer the computer can't find it. I have a Mac with Snow Leopard. I tried to detect the printer with another device and it can't find it. Is there a port that needs to be open for wireless printers? Because I tried putting the routers firewall settings for the device to its lowest and the computer still can't find it. Let me know. Thnx.

• Internet wireless connected with limited access, windows vista

  - by Wawa wiya

  Hello I had some malware in my computer so I did a bit of manual work to remove it including resetting TCP/IP. Now the malware is gone. I can see my home wireless network and I can get connected to it but when connected I get the Internet wireless connected with limited access message. When I go to the IE I cannot browse. When I tried to ping 192.168.1.1 I got an Error Code 1231 Unconnected Network Problem. I have deactivated my Windows firewall as I thought it could be hyperactive security. Still no luck. I have Norton but it is not active, I have also Avast and AVG installed but they are not active. Any ideas?

• is there a way to prevent network manager from storing the password for a wireless network

  - by tolomea

  Our corporate wireless network uses continuously changing passwords with RSA tokens. So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked. Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked. Is there some way to prevent it from storing my password for that network? Or perhaps someway to get the gnome keyring to not store it?

• Keeping the wireless connected.

  - by casr

  I’m running OpenBSD on a computer which is connected via wireless to the network. It is a well supported NIC and I’ve had no problems with it from a hardware perspective. Unfortunately my wireless access point occasionally loves to forget it’s settings. I then have to help it remember. However, in this intervening time my OpenBSD box drops the connection and then does not automatically reconnect. I have alleviated my problems by running this simple script in the background: #!/bin/sh while [ 1 ] do ping -c1 192.168.1.254 > /dev/null if [ $? = 1 ] then sh /etc/netstart ral0 > /dev/null fi sleep 30 done [Ping the access point. If there is no response attempt to reconnect.] It seems to me to be a very suboptimal solution. Has anyone else come across a better way?

• VMware Fusion on MacBook Pro running Vista, not working after installing a wireless card

  - by Shelley

  A tech friend installed VMware on my Mac so I could use my Windows programs as well. It worked great until I inserted my Sierra 881 USB wireless card while in VMware trying to get to the internet while on the road. It worked briefly, then the AT&T Communication manager won't respond when you click on the icon, I can't open Network and Sharing center, I can't sync my palm - shows it can't connect. Looks like it messed up several things, along with not being able to connect to the internet while in windows. This wireless cards works directly from the Mac - but I need internet while in Windows for some work I am doing. How do I uninstall this - when I try - it just gives me an endless reloading circle - not doing anything. I really need to sync my palm and get back to the way it was. I don't know much about VMware at all and I don't have access to my friend right now to get help.

• What is causing my wireless problems?

  - by user34629

  I have a Dell XPS M1330, since I moved to my new house, the wireless barely works on it, my housemates report no problems, so I guess it's something to do with my laptop. It's eratic in normal mode, sometimes not working for days, usually working on-and-off, forcing me to reload pages a few times before they work, etc. It works perfectly in safe mode, the driver I'm using is the Intel PRO/Wireless 3945ABG Network Connection, version 12.4.4.5, with a date at 26/10/2009, the most recent one I could find, bluetooth is not enabled, and I'm running Vista 32-bit Home Premium, which it shipped with. I also tried disabling IPv6 and resetting the IP stack, both to no avail. Can anybody help me?

• Remote Desktop connection breaks the wireless connection

  - by Michal Talaga

  When I connect to my Windows 8 Professional machine via Remote Desktop (RDP) I almost always get my WiFi connection broken. The setup: T61P Lenovo Laptop + W8 at home Wireless Router with NAT forwards connections to that machine Windows 7 laptop at work connecting to the home laptop When I connect, very often I get to login and suddenly connection is lost and I cannot reconnect again. When I get home I find my WiFi connection is still connected to the Access Point but does not function. Can't even ping the router. What is strange is that disabling wireless with the hardware switch and enabling it again doesn't help. The only way to make it works again: - Reboot - Disable wifi with hardware switch AND disable the network card in Device Manager, then enable both I did not have this problem on the very same laptop when it was running Windows 7. Any hint how can I find where the problem is?

• Windows 7 computer apparently connected to working wireless network but can't access router page or internet

  - by Hemmer

  I can consistently connect successfully to both the router and the internet using both my phone and two different computers which strongly suggests that the issue is at the desktop end. Only my Windows 7 desktop machine has stopped getting internet connectivity. It manages to connect to the router's network using the Windows 7 wireless dialog, but can't access either the router configuration page (192.168.1.1) or the internet in general once connected. The strange thing is the wireless network icon in the notification bar shows a full strength signal, sometimes with the yellow warning triangle. The output of ipconfig /all is: Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Broadcom 802.11g Network Adapter Physical Address. . . . . . . . . : 00-12-17-94-98-90 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.102(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 08 June 2011 10:32:16 Lease Expires . . . . . . . . . . : 08 June 2011 12:32:16 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 194.168.4.100 194.168.8.100 NetBIOS over Tcpip. . . . . . . . : Enabled I've tried renewing DCHP settings disabling IPv6 resetting TCP stack uninstalling and reinstalling WLAN card drivers I've not installed anything new or made any changes to my knowledge, this just happened out of the blue.

• Can I set up a 2nd home wireless router, with router2 connecting to the internet through a desktop which is wirelessly connected to router1?

  - by gil b.

  Hi, I apologize for the crudeness of my MSPaint drawing, but please view my diagram of what I'd like to accomplish: Proposed home network architecture Currently, all devices are connected to 1 wireless router. I would like to make my own subnet, with a box in-between my subnet and the shared wireless router, so that I can learn about IDS, traffic analysis, etc. I was also given a cisco PIX firewall to play around with, and it'd be an added bonus if I could incorporate that into my network. The reason for this proposed architecture is so that I can monitor all MY traffic, without seeing anything going on with my roommates' traffic. my MAIN Question is, is it possible to have my desktop connect to the wireless router with internet via wireless card AND share that connection via the ethernet card, hooked to wireless router 2? cable modem - wireless router - desktop pc connected wirelessly - wireless router 2 getting internet from wired connection to desktop pc - laptops connected wirelessly The PIX can be left out for now, but I'm wondering if it could eventually be incorporated? THANKS!

• Why do I have inconsistent network issues with my laptop's wireless?

  - by Jason

  I'm having trouble with my laptop Internet connection. It's patchy at best and resets or freezes a lot. The signal strength is also random. I thought it might be a driver issue but now I don't know. Three other computers using the same wireless network run well. I've switched out wireless routers so I don't think it's the router. I thought it might be the laptop's internal wireless card but I just bought an external USB network card and I'm still having problems. Specs Lenovo T-60p Windows 7 Ultimate Edition Patches/drivers are up to date I only use one of the below at a time, disabling the other: Intel PRO/Wireless 3945ABG v. 13.3.0.137 (Internal wireless) Medialink Wireless-N USB 2.0 Adapter (USB wireless) Any ideas on what might be the problem?

• I have a problem with a AE1200 Cisco/Linksys Wireless-N USB adapter having stopped working after I ran the update manager in Ubuntu 12.04

  - by user69670

  Here is the problem, I use a Cisco/Linksys AE1200 wireless network adapter to connect my desktop to a public wifi internet connection. I use ndiswrapper to use the windows driver and it had been working fine for me untill I ran the update manager overnight a few days ago. When I woke up it was asking for the normal computer restart to implement the changes but after rebooting the computer, the wireless adapter did not work, the status light on the adapter did not light up even though ubuntu recognizes it is there and according to ndiswrapper the drivers are loaded and the hardware is present. the grep command is being a bitch for some unknown reason today so this will be long sorry Output from "lspci": 00:00.0 Host bridge: Advanced Micro Devices [AMD] nee ATI Radeon Xpress 200 Host Bridge (rev 01) 00:01.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RS480 PCI Bridge 00:12.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB600 Non-Raid-5 SATA 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI0) 00:13.1 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI1) 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI2) 00:13.3 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI3) 00:13.4 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI4) 00:13.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB Controller (EHCI) 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 13) 00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI SB600 IDE 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB600 PCI to LPC Bridge 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RC410 [Radeon Xpress 200] 02:02.0 Communication controller: Conexant Systems, Inc.

• Intel Wireless 4965AGN not achieving N throughput when connected to an Airport Express N network

  - by BenA

  I have an Intel Wireless WiFi Link 4965AGN adaptor in my laptop (HP Pavillion dv2000 series) which is connecting to a 5Ghz-only 802.11n network provided by an Apple Airport Express. The network is using WPA2 encryption. My desktop is also connected the Airport, via a Linksys WUSB600N USB adaptor. Both are running with the latest drivers, and the Airport is running the latest firmware. The Airport is also configured to use wide channels. The problem I have is that I never get throughput above 4MB/s when transferring files between the two machines. Even a pessimistic calculation shows a 270Mbps network as being capable of transfer rates at well above 10MB/s. I'm pretty sure I've isolated the issue to being the Intel adaptor, as wiring the desktop to the AP, and using the Linksys adaptor on the laptop immediately yielded speeds limited by the 100MB/s ethernet connection. I know that 802.11n is still a draft standard, and so mixing kit from different manufacturers can easily lead to poor results, but I was just wondering if anybody else out there has had success with this Intel adaptor on an N network? Or even better, connecting it to an Airport Express? Can anybody give me any advice on how to troubleshoot this issue? I should also mention that the Airport Express doesn't allow you to manually specify channels when running in N mode, and that I've been able to rule out interference from other Wireless LANs by scanning. There aren't any other 5GHz networks in my area. All ideas welcome! Update: A while later, I've just updated to the most recent drivers for both the Intel chip in the laptop, and the USB adaptor. Unfortunately this hasn't improved things :(. If anybody has any advice it would be be gratefully received.

  I installed ubuntu-server 12.04 on my PC , and I use an usb wireless card to join the network. It works ok when I boot up my PC , but the wireless disconnects after a while. I pkill wpa_supplicant and reload the driver rtl8192cu , then it works a again. Then it disconnect again after about a random minutes. Here is the syslog: 22384 May 29 21:49:27 homecenter kernel: [ 6450.459313] wlan1: authenticated 22385 May 29 21:49:27 homecenter kernel: [ 6450.459535] wlan1: associate with f4:ec:38:45:62:74 (try 1) 22386 May 29 21:49:27 homecenter kernel: [ 6450.469080] wlan1: RX AssocResp from f4:ec:38:45:62:74 (capab=0 x431 status=0 aid=3) 22387 May 29 21:49:27 homecenter kernel: [ 6450.469085] wlan1: associated 22388 May 29 21:49:27 homecenter wpa_supplicant[2342]: Associated with f4:ec:38:45:62:74 22389 May 29 21:49:27 homecenter kernel: [ 6450.481933] ADDRCONF(NETDEV_CHANGE): wlan1: link becomes ready 22390 May 29 21:49:27 homecenter wpa_supplicant[2342]: WPA: Key negotiation completed with f4:ec:38:45:62:7 4 [PTK=CCMP GTK=CCMP] 22391 May 29 21:49:27 homecenter wpa_supplicant[2342]: CTRL-EVENT-CONNECTED - Connection to f4:ec:38:45:62: 74 completed (auth) [id=0 id_str=] 22392 May 29 21:49:38 homecenter kernel: [ 6461.472014] wlan1: no IPv6 routers present 22393 May 29 21:49:38 homecenter ntpdate[2263]: step time server 91.189.94.4 offset 0.012758 sec 22394 May 29 21:49:51 homecenter ntpdate[2404]: step time server 91.189.94.4 offset -0.001190 sec 22395 May 29 21:54:38 homecenter kernel: [ 6762.052030] wlan1: deauthenticated from f4:ec:38:45:62:74 (Reas on: 2) 22396 May 29 21:54:38 homecenter wpa_supplicant[2342]: CTRL-EVENT-DISCONNECTED bssid=f4:ec:38:45:62:74 reas on=2 22397 May 29 21:54:38 homecenter kernel: [ 6762.064744] cfg80211: All devices are disconnected, going to re store regulatory settings 22398 May 29 21:54:38 homecenter kernel: [ 6762.064752] cfg80211: Restoring regulatory settings 22399 May 29 21:54:38 homecenter kernel: [ 6762.064757] cfg80211: Calling CRDA to update world regulatory d omain 22400 May 29 21:54:38 homecenter kernel: [ 6762.069938] cfg80211: Ignoring regulatory request Set by core s ince the driver uses its own custom regulatory domain 22401 May 29 21:54:38 homecenter kernel: [ 6762.069943] cfg80211: World regulatory domain updated: 22402 May 29 21:54:38 homecenter kernel: [ 6762.069945] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) 22403 May 29 21:54:38 homecenter kernel: [ 6762.069949] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KH z), (300 mBi, 2000 mBm) 22404 May 29 21:54:38 homecenter kernel: [ 6762.069952] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KH z), (300 mBi, 2000 mBm) 22405 May 29 21:54:38 homecenter kernel: [ 6762.069956] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KH z), (300 mBi, 2000 mBm) 22406 May 29 21:54:38 homecenter kernel: [ 6762.069959] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KH z), (300 mBi, 2000 mBm) 22407 May 29 21:54:38 homecenter kernel: [ 6762.069962] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KH z), (300 mBi, 2000 mBm)

• Domain authentication over OPEN wireless pre-logon (Windows 7 Pro) - No logon servers avail

  - by Shadow00Caster

  I have a plethora of laptops that are joined to an AD domain. I have an enterprise wireless system setup, the users of these laptops will be using an OPEN unsecured SSID which will ultimately have a captive portal that uses Radius-AD auth and firewall rules to allow access pre-captive portal auth to the proper ip's/ports of DC's etc for auth etc. I already have other laptops/users connecting to another SSID with 802.11x and SSO, all works perfectly pre-logon etc. My problem is with this open network, for some reason I cannot get the machines to auth to AD. The laptops connect to the wireless network, I confirm this on the controller and can ping the laptop at startup. I sharked the wires on the 2 DC's that these machines auth to, I can see a DNS SOA update from a laptop im testing with and can ping that test laptop from both DC's. When I try to logon, "There are currently no logon servers available to service the logon request." The shark shows no incoming connections to either DC even though the laptop is connected and pingable. Any help is greatly appreciated.
