• Setting reply priority on Wifi network with QoS?

  - by Omega

  When using a Station and Access Point that support QoS over Wifi, is it possible to set the priority (= Traffic Identifier = TID = QoS channel) of the reply? For example when sending a ICMP ping request using a high priority (= QoS channel), is it possible to force the station to use that same priority (= QoS channel) when sending the reply? A related question: Is it possible to force the station into using a different QoS channel?

• How do I get more information on a potential network freeloader?

  - by Dov

  I have a home network set up, complete with a relatively good password. I'm in Mac OS X 10.6 (Snow Leopard) and have been noticing, on occasion, a computer showing up in my Finder's Shared section, that is not one of my own (the "pe-xpjalle" box pictured below). He has a tendency to come and go. How can I figure out his MAC address or something, so I can block him? I checked my "Logs and Statistics" in the Airport Utility, and didn't see that computer under DHCP clients. I'd rather not change my password, since I have quite a few devices I'd have to update. Is there any other reason he's show up on my network besides having guessed my password? Update: I fixed the Dropbox URL above (how embarrassing, I'm new to Dropbox. Thanks for the heads up, Doug.) Update 2: I tried clicking on "Connect as..." just for the hell of it, and got the dialog below. Now I have even less an idea what's going on than before. I don't have Parallels of VMware running, just the following: Transmission, NetNewsWire, Mail, Things, Safari, iTunes, Photoshop, Pages, Yojimbo, Preferences, AppleScript Editor, Software Update, Airport Utility, and Terminal. I don't think any of those create a virtual network machine, right? And no VMware machine of mine has ever had a name resembling "pe-xpjalle". Update 3: I just changed my passwords on both my N- and G-only networks, and I'm still seeing this, so I highly doubt that it's someone who's figured out my password (twice now). I'm really stumped.

• How to install Archlinux on a acer emachines em350 ?

  - by zillion

  Do a 64 bits version will work better if the cpu is 64 bits capable ? Can I remove all added stuffs on Archbang or CTKArchLive to return to plain Archlinux with openbox that I can configure myself easily, so I can install Archlinux faster ? I tried and installed Arch properly but I need to install the broadcom bcm 4727 driver (b43,wl,sta,open source), which driver do I need and how can I install it by my usb on Archlinux CLI made with base, sudo and wireless_tools only ?

• iPod touch has extremely slow wifi, drops packets - only on my router

  - by mskfisher

  I just purchased an iPod Touch. I am having a lot of trouble with its speeds on my Tenda W311R, but it has no speed problems on my neighbor's Netgear router. It will connect and authenticate to my network, but the Speed Test app from speedtest.net shows rates near 20-50 kbps. If I run the speed test immediately after powering the iPod on, it will get speeds of 10-20 Mbps, like it should - but the speeds slow down to the kbps range abut 10-15 seconds afterward. I get the same behavior with encryption and without encryption, and regardless of N, G, or B compatibility settings in the router. I've tried rebooting the iPod and resetting the network settings, but it's still slow. I've tried pinging the iPod from another computer, and it shows about 40% packet loss: $ ping 192.168.0.111 PING 192.168.0.111 (192.168.0.111): 56 data bytes 64 bytes from 192.168.0.111: icmp_seq=0 ttl=64 time=14.188 ms 64 bytes from 192.168.0.111: icmp_seq=1 ttl=64 time=11.556 ms 64 bytes from 192.168.0.111: icmp_seq=2 ttl=64 time=5.675 ms 64 bytes from 192.168.0.111: icmp_seq=3 ttl=64 time=5.721 ms Request timeout for icmp_seq 4 64 bytes from 192.168.0.111: icmp_seq=5 ttl=64 time=6.491 ms Request timeout for icmp_seq 6 64 bytes from 192.168.0.111: icmp_seq=7 ttl=64 time=8.065 ms Request timeout for icmp_seq 8 Request timeout for icmp_seq 9 Request timeout for icmp_seq 10 64 bytes from 192.168.0.111: icmp_seq=11 ttl=64 time=9.605 ms Signal strength is good - I'm never more than 20 feet from my access point, and it exhibits the same behavior if I'm standing next to the router. It works just well enough to receive text, but videos don't work at all. App downloads are hit and miss. I've tweaked just about all of the settings I can see to tweak, and I'm at a loss. I have also been searching Google for the past three days, all to no avail. Any suggestions?

• USB Wifi will not connect on Windows 7 (Even though the driver installs OK)

  - by Pete Roberts

  Windows 7 will not connect to a WiFi Netowrk using a USB Network Adapter. I have 3 adapters, A Senoa SUB 364 (EXT), a Repeatit SU2410 USB V2 and a ZYXEL G202. All of these devices install OK on Windows 7 Home Premium on my Destop PC (64 bit) and on my Asus Wii Netbook (32 bit). In each case the adapter can be enabled/disabled and the driver properties says it is working correctly. When I try and connect to a network Windows 7 behaves as though the adapter does not exist and reports no networks. The Wii has an integrated adapter which works perfectly under Windows and connects to either of the 3 networks available to me. I have done all the checks I can on the configuration. What seems odd to me is that it happens to all 3 devices on 2 different windows 7 PCs both of which are working perfectly in any other respect. This suggests the common denominator is me and I must be doing something wrong.. what's also strange is that I cannot find any similar problems being reported on any of the forums. From what reading I've been able to do it seems like the new wifi virtualisation thingy in W7 is not recognising the adapters which suggests I', missing a configuration option somewhere. Looking forward to finding out if I'm not alone or just being stupid. Pete

• Wifi Drops Connections with WPA2-PSK

  - by graf_ignotiev

  I run a small computer lab made up of 10 computers of identical hardware and software (Dell Latitudes with Windows 7 x64 Enterprise) and I use a ZyWALL 2WG as a router/firewall. Nine of the computers connect to the router over wifi using WPA2-PSK encryption while the last one is connected by ethernet cable. I'm having a problem where any computer connected to the wi-fi occasionally drops off the network (it cannot be pinged and the client cannot ping the gateway). It only happens on the wifi side and only when the encryption is WPA2-PSK or WPA-PSK. I tried using another router with a different make and model and had no problems. Thinking it could be a software error, I reset the router to factory defaults and installed the newest firmware (V4.04(AQI.8) | 04/09/2010), but still have the problem. The 802.1X log gives the following error User logout because of user disassociation. with this note WPA2-PSK:00242c582ece:logout where 00242c582ece is the mac address of the device. At this point I'm out of things to try and leads to follow. It looks like this user had the same or similar problem, but none of those proposed solutions work for me.

• Internet speed is suddenly slow only on my laptop, but it's normal in other devices

  - by Wael

  I have a TP-Link router connected to a ZTE modem, with 2 laptops, a tablet, 2 phones connected via the router's WiFi, and an additional desktop connected via ethernet to the router. Today, my laptop started to have a very slow connection to the internet, which at first I thought it was the operator's problem to find out later on that it works fine on other devices. I tried to connect directly via WiFi to the modem, but it was as slow. I cannot access facebook at all, google takes forever to do a search, and youtube barely works. The weird thing though, is that when youtube does work, the streaming is full speed. This happens also when I download a file! My browse is Firefox, but I used Chrome and IE9 with the same results. I work on Windows 7 Thanks for any advices.

• Delayed startup of network icon (wi-fi)

  - by Michael Dy

  When my Windows 7 Starter netbook boots up and after everything is loaded, it takes about five minutes before the network icon near the clock becomes functional. When there's an available wi-fi signal (which automatically connects to my netbook as preconfigured) after the boot, my netbook seamlessly connects to it even if the network icon cannot be clicked or accessed. (The icon is shown to be loading for about five minutes.) During this time, when I go to Network and Sharing Center, it takes the same time to load. So even while the icon and the Center cannot be accessed, I can surf the Internet. When my netbook was still new, it didn't have this issue. How do I fix this?

• Issues with ForceBindIP on Windows 7 (x64)

  - by Craig

  I am desperately needing a solution to binding certain applications to specific network interfaces. ForceBindIP seems to be my only solution. Although the website claims it works up to XP, Google says that many users running 7 have had it work successfully. I have UAC disabled, yet still: Does anyone know why this is happening? If not, does anyone know a viable alternative to ForceBindIP? I'm a gamer and I'm addictively trying to torrent on a secondary connection while playing games online.

• Dual NIC internet access

  - by JavaRocky

  Q1. If a computer had two NICs, lets say windows, on which interface would HTTP traffic (or any for that matter) go out on. Not sure how the routes table would look like. Q2. If one of the NICs link becomes unresponsive, would traffic be automatically routed to the other NIC? Thanks.

• Is is possible to change MAC address of a WiMAX USB adapter?

  - by Salman A

  Wondering if it is possible to change the MAC address of a WiMAX USB adapter (read WiMAX, not Wi-Fi) manufactured by Motorola, ZTE, Intel etc. I've tried a few tools that did changed the MAC address of the adapter to another valid MAC address (that I coped from another equipment made by same company) but then I was not able to connect to the network, the connection software took long time stating "obtaining IP address"; then few seconds after it got one said "lost IP address". Wondering if changing MAC address of such devices actually work.

• Why does my internet connection get cut off and is slow sometimes?

  - by user3716773

  When I first set up my internet connection it was all good and fast but after 2 months the connection started to be slow sometimes and sometimes there is no connection until i turn off my wifi then turn it on again on the laptop. And sometimes I have to restart the router. I don't know what's wrong. I think there is something wrong with the router because this problem happens with my brother's laptop and my phone too.

• Is there any way to abstract IP address during ssh?

  - by Vivek V K

  I have a server which is in the middle of a forest. It is connected to the Internet via a microwave link and an ADSL link.Hence it has two different static IP addresses. Now if there is heavy rain, the microwave link breaks and I should use the much slower ADSL link. And I ping the microwave ip time to time to check if it is up again . But at times, I end up using the very slow ADSL link even if the microwave link is back up. Hence I need a way to automate this in the following way. 1.I need to abstract the IP address of the machine with some other name which when I use ssh or sftp, will poll both the IP and connect me to the best one. so for eg: if I say ssh -Y name@server, It should first try to connect to the microwave link if it cant, then connect to ADSL. 2.Suppose the first time I connect, the microwave link is down so it connects to ADSL, I need it to dynamically change to the microwave link once it is working again. Is this even possible?

• ZigBee Maximum Bandwidth

  - by Kris

  What is the maximum rated bandwidth for ZigBee? I can't seem to find this information anywhere, not even on the ZigBee Alliance website at http://www.zigbee.org/ I did find some information elsewhere, but it dated back to 2004, so I'm guessing it's different now that it was 5 years ago. Thanks!

• How could Google Latitude find my exact PC location with no GPS or public wifi?

  - by Mike

  I found a similar question here but I still don't get it. You see, I live in a small town and every time I check my IP location via online services or speed test websites, my location appears to be my ISP server location (which in my case is 250 miles away). But when I tried Google latitude, it pinpointed my exact location within less than 100 meters! I use Windows Vista, Google Chrome, and when I got the message that "Google is trying to locate you", I agreed just to check what the result will be. It was scary, very scary! What I've come up after reading the above link is that Google have a kind of extensive WiFi database locations. That could be understandable with the case of public and open WiFis that are used with a lot of people. Some of them might be using applications that could gather location data and somehow this information ends up in giant Google databases. From those, Google could pinpoint a WiFi location based on its MAC address along with these bits of info that have been gathered via various sources. The issue here is that my WiFi is private, I don't even broadcast my WiFi name. So how on earth did Google find my exact PC location? Please break down the answer in layman's terms as possible.

• How can I stream audio signals from various devices/computers to my home server?

  - by Breakthrough

  I currently have a headless home server set up (running Ubuntu 12.04 server edition) running a simple Apache HTTP server. The server is near an audio receiver, which controls a set of indoor and outdoor speakers in my home. Recently, my father purchased a Bluetooth adapter, which our various laptops and cellphones can connect to, outputting the music to the speakers. I was hoping to find a solution that worked over Wi-Fi, namely because it won't cost anything (I already have a server with an audio card), and it doesn't depend on Bluetooth. Is there any cross-platform (preferably free and open-source) solution that I can use which will allow me to stream audio to my home server, over my home network, from a wide variety of devices (laptops running Windows/Linux or cellphones running Android/BB/iOS)? I need something that works at least with Windows and Android. Also, just to clairfy, I want something that simply allows devices to connect to my server and output an audio signal without any action on the server end (since it's a server hidden away near my receiver). Any subsequent connection attempt should be dropped, so only one device can be in control of the stereo at once.

• Thinking of Powerline adapters for networking

  - by Henderson McCoy

  will powerline work as good as wifi I am now in a large house (renting a room) and the router is in the front of the house and I am in the back. Don't know if wifi will have the range and stability so I am looking at all the alternatives from running a long cable to powerline. looks like a powerline adapter set will cost about $50 http://www.bestbuy.com/site/Actiontec---500-Mbps-Powerline-Home-Theater-Network-Adapter-Kit/5215483.p?id=1218625358741&skuId=5215483 has anyone use these or other powerline adapters? how is powerlines speed? Are they more stable then wifi? powerline cost is good i am just currious about the performance

• Wifi network undetectable on a Lenovo G470

  - by Rex

  I have a WPA2 secured network with a visible SSID at home that works perfectly fine with a Dell laptop,a HP netbook and sundry mobile phones. When I try connecting my sister's Lenovo G470, it refuses to detect the wifi network no matter what, but shows up the neighbors' networks. The Lenovo also works correctly at her office. Both laptops run Windows 7. Already tried/checked the following: Manually configure wifi network settings (copied over from the Dell) Ensure there is no MAC address filtering on the router. Ensure router DHCP server is not running out of addresses to assign (I have set it to allocate upto 10). Reboot laptop, router etc. Is this a known problem, and is there anything else one could try? Update - The problematic Lenovo uses Windows 7 Home Basic while the Dell that works uses Home Premium and the HP netbook uses Starter edition - if that makes any difference. Further update - It is able to connect if I reboot into safe mode with networking. However in 'normal' mode it shows up the network sporadically, and then says there was an error connecting to it. All the network parameters, password, encryption, etc etc are EXACTLY the same as they are on the Dell.

• Cannot access SMC8014WG-SI provided by TimeWarner/RoadRunner administrative interface...

  - by Matt Rogish

  I just received installation of RoadRunner internet/TV/Voice and I was given a wi-fi router from the TimeWarner folks. The model is a SMC SMC8014WG-SI. Unfortunately, the password it uses is WEP and that is, as we all know, completely insecure. The tech that was here didn't know how to change it to something like WPA2 w/TKIP, and I was on hold for 20 minutes with the TimeWarner folks before I gave up. My problem is that the default web interface (http://192.168.0.1) isn't responding. I can ping it, I can access the internet through it, but I can't get to the admin interface. I did a "hard reset" of the device but still no dice. My suspicion is that the wi-fi admin interface is disabled (a common setting) but the wired interface isn't working on either of my two laptops (I've tried two laptops with two different cables, no link light activated). Am I SOL? Did they lock this down so I can't do what I want to do? Worst-case is I just hook up my go-to WRT54G router to the other modem and leave this one turned off, but I'd rather use their hardware to avoid any "It's not our problem" in the future. Any thoughts? Thanks!!

• What is a reasonable range for signal strength when next to my router?

  - by Jeff

  I know that these things depend largely on specific hardware but I don't even know if I am in the neighborhood. What would a reasonable range of signal strength be when my device is less than 5 feet from my router? House3 is my main router at 61% strength and that seems very low! Repeater is my... repeater which is 50' away in the next room. I'm not terribly concerned with the Repeater until I get my main router settled.

• Shareing two internet connections on my laptop running Windows XP

  - by ashwnacharya

  I have two internet connections, one is internet via our organization's corporate LAN network, and the other one is mobile broadband via a USB modem Is there anyway I can share internet connections and use them simultaneously? I want to use the corporate LAN network for normal browsing and connecting my email client, and I want to use the USB modem for establishing a VPN connection. Will I be able to maintain both the connections simultaneously? Can I have parallel downloads, one using our corporate network, and the other one using the mobile broadband? Will I be able to switch my browser between these two connections? My laptop runs Windows XP Service Pack 2.

• Wi-Fi performance in Windows 8 RP on a MacBook Air (mid 2011)

  - by Steven Lu

  I was able to install the Boot Camp Windows software using the executable that it provided, and there are no unrecognized or unknown devices in Device Manager. Wi-Fi works but it seems to be limited to an extremely slow 1.5Mbits. Network Center reports an 802.11n connection (at 65Mbps usually) but transfers never reach above about 200kB/s. Being limited to 1/20th of the connection speed of my internet service is quite frustrating. Does anybody experience the same issue? I have been trying to identify the Broadcom Wi-Fi chipset and a driver that I could try to upgrade to but I have made very little progress on Google on this front.
