Ubuntu Networking :: Natty Lost My Wifi Card / What To Do?
Apr 29, 2011
Reading recent posts, it seems that 11.04 has seriously screwed wifi.
I have an Advent QRC430 laptop which worked perfectly until I upgraded to Natty. Now wifi is broken. The wifi driver is rt73usb.
When I run lspci in terminal, no wifi card is listed. Running rfkill shows wifi hard blocked, but the switch on laptop makes no difference.
I've installed and run Hardware Lister - this shows wireless interface "has been disabled"
After being prompted by UpdateManager, I upgraded my Compaq Presario CQ71 from 10.10 to 11.04 yesterday. Most things seem fine, except that my wifi is disabled (it was working fine in 10.10).
Our Acer 5820T handles Natty nicely in all respects except for the wifi not working. It was fine under 10.10. It uses the Atheros ath9k driver ... details:

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:
Code:
I notived the following problems in /var/log/kern.log
I have a Broadcom BCM4318 that isn't working with the B43 or the other (I tried installing both and while they supposedly installed successfully, neither shows up in the Additional Drivers tab for me to enable.) I tried using both sets of directions stickied up at the top of this forum. Neither seems to be working for me (no guarantees on whether I did it right) though the B43 is apparently the one I need.Disclaimer: I'm a total newbie to using command line and a new convert from Windows so I'm rusty at navigating and making things work, though things are finally starting to make a little sense after two days of hacking at it.
I have just upgrade to natty from maverick and my usb wifi dongle doesn't want to work. The usb wifi adapter i use is a Thonsom Speedtouch 121g. When using ubuntu 10.10 it work's fine after installing the package linux-firmware-nonfree, but after upgrading to natty it has stop working (the linux-firmware-nonfree package is installed [don't know if is the same version or an upgraded one]).
The network manager doesn't display available wifi nets. The output for lsusb is:
Bus 001 Device 004: ID 06b9:0121 Alcatel Telecom SpeedTouch 121g Wireless Dongle
I've had recurring problems with Ubuntu wifi on my Thinkpad before. Usually powering down and toggling the physical wifi switch off, then toggling wifi on again after the system has booted would solve the problem. This time that isn't working. Wireless is completely absent from the network-manager applet. Wireless works for me 99% of the time for me, but every few months will "disappear" for some reason. Does anyone have any advice or know a thread they can point me to? I've posted the results for 'lspci -k', iwconfig and 'lshw -C network' bellow:
I was happily running Ubuntu 9 but since I cannot get security updates for it anymore I had to upgrade to 11. Now I'm on Natty, and the "NetworkManager" apparently cannot deal with my latop's wifi card which worked fine for years under ubuntu 9. The laptop is a Dell latitude D610 and the card is an intel ipw2200 minipci. I used to just run /etc/init.d/network restart after I logged in to get the wireless to come up, if it failed by itself, but now I get a message that that's deprecated. Nice.
I'm running WPA. If I don't create a wireless configuration in the network manager, wireless never connects. Ever. If I do create a configuration, the connection comes up for about a minute, and then drops. And then comes up. And then drops. And then comes up. And then drops. It's insane. Also, I get a series of "Auto <ssid>" entries in the NM settings area.I dug around in /var/log, but all of the wpa_supplicant logs are of size 0, except the gzipped backups, which are all size 20. Go gzip. The syslog has some messages in it about 4-way handshake failed, and association taking too long, but since the laptop has no network connection I don't have an easy way to post those here.I just want the wireless to come up, by itself, when I turn on the laptop like it used to. I don't want to have to deal with retyping the (long and complicated) WPA password every time I wake up the machine, nor deal with the "keychain." How do I get there?
I was running a patch of my wifi connection and now i have NO wifi at all. I am totally lost right now. i have been running throught all the threads but nothing is really working. Is there a way do a full system restore (like windows) that will undo all my mistakes? my wifi has always worked until i screwed something up!
i have a acer aspire one (zg5) with a 2 week old installation of unr. shortly but not immediately following my last update my wifi no longer functions. when i go to the network connections tab in my toolbar it does not list available wifi networks. does not apparently recognize wifi capability at all. but the wifi worked right off the rip on new install.
I turned down my txpower with the command: sudo iwconfig wlan0 txpower 3 Which works to fine turn down my broadcast power from the default value of 15 dBm to 3 dBm. But it is reset every time I restart Ubuntu 11.04 to the default value of 15 dBm. How do I save my modified txpower settings so they don't reset after a restart? It is really annoying having to re-enter the command every time I reboot my computer!
I am running Ubuntu 10.10 Netbook Remix on a Toshiba Netbook NB300. After performing an upgrade I find myself unable to connect to my wirless network and have lost the wifi icon in the task bar. Ethernet connectivity is however working.
iwconfig shows: wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off ifconfig shows
[Code]...
I need to take to bring back wireless connectivity to my netbook and restore the wifi icon to the task bar.
I suppose this was caused by an update, I don't know. I just know that my wireless card is no longer seen by my Ubuntu 8.1. Maybe I should be in the newbie area. Isn't there a way I can wake it up with modprobe?
Ubuntu 9.04 running on a Dell C640 with a Dell TrueMobile 1150 wireless card. Works perfectly under XP. Ubuntu can't find it. Wired networking finds the internet perfectly (though I'm still working on getting samba set up correctly for file/print sharing on my XP LAN).
I'm thinking I need a driver, maybe? Can't seem to locate one.
i just thought the last few days about trying Ubuntu. so i did. i got a nice and fresh copy of Ubuntu Desktop version and installed it, everything worked great except my wireless usb 2.0 card. the only internet connection i have under windows is Wifi and i hoped that my dongle will be recognized by Ubuntu automatically...(naturally, it wasn't the case.)
so my adapter looks exactly like this one here, except for the color, it's white and it has my WISP's name written on it (i got it from them, along with a cd that offers win xp/98/me drivers...)
so even everest sees it's atheros and it's the Atheros AR5523 chipset.
i also have windows 7 64bit drivers if they help...
anyway, i can't get it to work and cannot access the internet any other way when on Ubuntu, so i have to use an already-saved driver..
I have downloaded the driver installed it, and it works fine. But i can't get to turn it off. I do have the ability to unload the driver's kernel modules and the sysyem does not see my card after that. That's ok, but i'm thinking it still uses my battery power. The wifi led is always on no matter what i do. The fn+<wifi key> doesn't to anything.
i installed ubuntu on my friends laptop but when he tries to connect to his network and enters his wep key the box disappears for a few second and comes back again...The card is Atheros on a Toshiba laptop and it is detected , it finds the networks but the wep key is rejected every time without a error
I've just installed Ubuntu 10.04 on my old X30 alongside my fully working 8.04 and have strange wifi problems under 10.04 (under 8.04 it worked out of the box): - no available networks are shown - running "sudo iwlist scanning" results in "eth1 Interface doesn't support scanning : Device or resource busy" - without any wireless configuration from my side I get this: sudo iwconfig eth1 eth1 IEEE 802.11b ESSID:"gxC6isQxFFJxEC)xCDxBAxAB xF2xFBxE3F|xC2TxF8x1BxE8xE7x8DvZ.c3x9FxC 9x9A" Mode:Managed Frequency:2.467 GHz Access Point: None Bit Rate:11 Mb/s Sensitivity:1/0 Retry short limit:8 RTS thrff Fragment thrff Encryption keyff Power Managementff Link Quality=90/70 Signal level=-8 dBm Noise level=-147 dBm Rx invalid nwid:0 Rx invalid crypt:63 Rx invalid frag:0 Tx excessive retries:1 Invalid misc:0 Missed beacon:0 A very strange ESSID there appearing out of nowhere...
This is the issue, and I have had this happen with a few card readers. I have a Alfa Usb Wifi adapter model number AWUS036H using the rtl8187 Chipset. It works fine, unless I plug in my flash card reader directly to the board. If I plug it in to a hub it works fine until I put a card in, I was also having the same issues using a USB Video Capture unit by the name of EASYCAP. This was also happening in XP. Must be some driver conflict of sorts.
Im looking for a pci wifi card for my media pc, I would prefer wired, but we are moving soon , so i dont want to take the time to run a wire through the house. Im looking for one that will work out of the box with Ubuntu.
so I had to reinstall Ubuntu.But now my Wireless card won't work. It used to work before (plug and play), and I have no problem with it when I boot from the CD.I cannot use my cable connection because as soon as I plug my computer in, the network crashes, the router doesn't respond, gets hot and refuses to work until I unplug it and let it cool off for 2 minutes.I'm using Ubuntu 10.10, Desktop PC.

I have discovered the world of freewares not long ago and it surprised me! To go a bit further, I have installed Lubuntu 10.4 LTS on an old laptop: HP Pavilion zv5326 with 256 Mo RAM.
Everything works fine except the wifi.
iwconfig returns for wlan0: IEEE 802.11b ESSID:"Livebox-afe5" Mode: Managed Access Point: Not-Associated Tx-Power=0 dBm Retry Long Limit:7 RTS thrff Fragment thrff Power Managementff
Ifconfig returns nothing for wlan0
From what I understand, my wifi card is recognized so I do not need to install a driver with ndiswrapper, right?
What should I do then? Is there a solution at all?
(Livebox-afe5 is the wifi connection I use with my other laptop.)
i m using backtrack 4 in vmware.i want to use my laptop in built wireless card to search for the near by wifi access point which it is not doing,, my wifi card is " Intel(R) PRO/Wireless 3945ABG Network Connection"
I got a new EDUP Wireless Lan PCMCIA Adapter to replace a busted SMC wifi card. I am running Ubuntu 9.10 on a Dell laptop. The OS will not recognize the new card. Here is some output code...
Finally took the plunge and upgraded my ubuntu studio to karmic from jaunty. I seem to be experiencing a problem many have, being that my wifi card (edimax) which worked on my previous distro is now not working at all. I've done a lot of research and found the problem seems to mainly be with broadcom cards, and have tried a number of things relating to those that have worked for others, with no luck.
My problem seems to be not that the drivers wont activate or anything like that, my problem is that under hardware drivers nothing appears at all. I have no drivers present, where most people are talking of 3. i have not found anyone else with this problem. My problem is compounded in addition by not being about to use a wire connection at all.
I just purchased a RALINK WIRELESS G PCMCIA WIFI CARD VISTA/LINUX (UBUNTU). It is supposed to be UBUNTU plug and play out of the box with no driver downloads needed.
I installed it but could not find a way to search the active Wi-Fi networks available like on my Actiontec card on windows xp. The wireless router/ethernet I have is an Actiontec setup for Qwest-DSL and Actiontec is the name of the wireless network.
Strangely I tried to choose setup a "new network" and entered Actiontec as the network name and it found the network and said it was connected to it. However the internet still is not working?
