Ubuntu Networking :: Wlan Card Is Not Working Any More
Dec 25, 2010
I'm a new user of Ubuntu and I think I need some help but let me mention before that I got this up working on a Debian system.My current kernel version is $ uname -r 2.6.32-27-generic.The problem is that my wlan card is not working any more such that my system freezes every time I enable networking with the hardware switch on my laptop.Therefore I bought a USB - WLAN stick and try to get this working.
Network Manager has the option "enable wireless" greyed out if I disable the hardware switch.If I enable the hardware switch and remove the module of my wlan CARD before (modprobe -r iwl3945) it says "wireless disconnected" for all networks.
I'm using Ubuntu 9.10 on a Lenovo ThinkPad T61 using an Intel PRO/Wireless 3945ABG. My laptop's ability to connect to a wireless network stopped last night, and I'm not sure why. It's definitely something on my end, as my roommate can connect to the internet on a Windows box. I can wire in without a problem, but that's a pain and my Ethernet cable got lost in the shuffle when I moved back to school. I've been able to get into this network before and nothing about it has changed. I've been able to hibernate and restart and such and nothing has ever needed to be reset.
The router's a D-Link WBR-2310. Wicd and Network Manager see the network (I'm back to using wicd) , but wicd appears to get stuck at "Obtaining IP address..." and says "Unable to connect: Cannot obtain IP address". I know my password is correct (I set up the router and I'm the CS undergrad in the apartment so I manage it), lspci sees the wireless card, ifconfig and iwconfig return information about the interface, dmesg|grep wlan0 doesn't seem to have anything terribly out of the ordinary, but here's that output:
Code: allyanncah@taliesin:~% dmesg | grep wlan0 [ 23.514202] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 36.609016] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 38.756143] wlan0: direct probe to AP 00:24:01:cb:4e:7e (try 1) [ 38.758791] wlan0: direct probe responded [ 38.758796] wlan0: authenticate with AP 00:24:01:cb:4e:7e (try 1) [ 38.760587] wlan0: authenticated [ 38.760609] wlan0: associate with AP 00:24:01:cb:4e:7e (try 1) [ 38.763318] wlan0: RX AssocResp from 00:24:01:cb:4e:7e (capab=0x431 status=0 aid=1) [ 38.763322] wlan0: associated [ 38.765502] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready .....
I've tried: - reinstalling wicd - uninstalling wicd and installing network-manager - restarting - shutting down and booting back up - restarting the router - sudo /etc/init.d/networking restart - taking the interface down and back up with ifconfig
I haven't changed anything recently in regards to my wireless card, and all the fixes I've tried are things I've done before without an issue. The only thing I'm wondering about is if doing a hard reset might have broken something (I know this is a cardinal sin, but there's a whole 'nother problem I haven't been able to fix with the OS hanging every once in a while over a VPN daemon when it tries to shut down or restart -- I've left it for hours to see if it actually gets anywhere and no luck, won't do a soft reset). I'm nervous about reinstalling the driver just because I've never had to do it and drivers are a finicky business. I imagine there's a config error somewhere?
I have a Dell Inspiron 1525 laptop using Dell Wireless 1395 WLAN Mini-card (This is what Windows Vista says I have). I have installed Ubuntu as dual boot with existing Windows Vista. Wireless is not working in Ubuntu but working flawlessly in Windows.

specific Ubuntu supported WLAN PCI-cards? This link shows a list of supported PCI-cards, but which is best: [URL] And the installation needs to be easy! I�ve tried installing these PCI-cards in my computer, useing Linux drivers, NdisWrapper, etc. Unforutately without any success:
- DWL-G510, Ralink Chipset, Ralink RT2561/RT61
- Realtek Semiconductor, RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller
I have bought a new laptop with win7 on it , I delete win7 and install ubuntu64 everything is ok but my wireless card won't work ( it is recognized) and even I can connect to INTERNET but nothing is download or upload so I have bought another usb wireless card but now when I connect this new card to my laptop it still tries to use the old one and so I could not connect to internet
Am having intermittent connectivity issues with my stock Atheros AR5212 on my Thinkpad X61 using Ubuntu 10.04. Am wondering if there is a known to be good b/g min-PCIe card that I can replace my AR5212 with that would be more solid in Ubuntu?
I have been using FC10, it works well with wlan for sometime and goes inactive after some time and hence network goes unavailable. Even after few attempts to reconnect doesn't help. Rebooting helps in bringing it back temporarily.
I have 2 wlan cards. wlan0 and wlan1. wlan0 is in AP mode(Master mode) using hostap. wlan1 is connected to another wireless network and is in Managed mode. Now I want to make a bridge between wlan0 and wlan1. I do it like that:
I upgraded Ubuntu to 11.04 I can NO longer connect wirelessly using my BCM4312 WLAN Card. It connected with no problems before dist upgrade using Ubuntu 10.04. Im really not sure why I cannot connect. I cannot even see my router in edit wireless connections settings. I can however see my neighbours routers who are using WPA2 encryption. But I cannot see my router.
I have uninstalled and reinstalled The Broadcom STA proprietry wireless driver several times using Additional drivers. This did not fix my issue.
I am connected by ethernet at the moment so I do have internet connection.
I'm having trouble setting up new Alix URL... system with a wireless card. I got the card from an old working Buffalo AirStation router. The card is a WLI-MPCI-G54 and is using Broadcom BCM4306 chip. I've installed Debian on the system.My goal is to make a wireless access point by using hostapd authentication service. I thought it might be a good idea to verify that the wlan-card is working properly first, but it can't seem to detect my local wlan.
I have a Dell WLAN 1397 Half Minicard, 802.11 b/g card in my laptop, and I can't seem to get ubuntu to work with it. I tried this method:
1. Synaptic Pack Manager 2. Check "Install from Boot Disc" 3. Reload 4. Install and apply bcmwl-kernel-source 5. Reboot
This didn't work for me, so I tried entering sudo apt-get install bcmwl-kernel-source and that also didn't work. Another thing I tried is formatting my Ubuntu partition and reinstalling, and retrying both of those methods. The ethernet port does work, however.
I've just got a TP-Link wn-851n PCI WLAN card, and the problem is that ubuntu can search for the network, but I can't join into the network after typing the password. I'm sure that it is correct as m Windows notebook is also using that network.
Taking a look in dmesg, and it start to loop this message after I joined the network.
I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.
I have a Dell Latitude D800 with a Dell Wireless 1350 (802.11b/g) WLAN miniPCI Card. I need to install wireless on this laptop but I see no wireless card when I know I have the above wireless card. Here are some commands that I ran that I might prove useful:
Inspiron 1525 - Wireless 1395 WLAN Mini-Card I passed two days browsing the net looking for a solution to my problem but no way.. Im running ubuntu 10.10 in my inspiron via VirtualBox and my wireless card is not detected by ubuntu.. I installed the bcmwl6.inf driver with the wrapper and it show me in wireless window that the hardware is not present.. So checked that in the terminal by typing :
I have just installed Ubuntu 9.10 on an Acer TravelMate 290E. I've got internet connection through the Ehternet Cable, but when I plug in the D-Link WLAN USB device, although the system recognises it, it is disconnected. How can I connect the WLAN USB device adn get it to work?
I have a desktop and laptop both running ubuntu 10.04. I have them going through a wireless router, the desktop is wired of coarse. I installed just about all the samba packages in synaptic that have the little ubuntu symbol next to them on both desktop and laptop except the Kde and document packages. I installed the two necessary packages to enable personal file sharing to work. But I can't seem to access files back and forth from these computers.
Installed F14 on my daughters HP Pavilion a131On. I rebooted multiple times. Do I need to activate something? I'm new to all of this but read through many threads to do as much as I could myself. I used the GUI to load the rt3070 drivers rather than rpm. The GUI is easier I think and should be equivalent. Please let me know what else I need to do. Fedora has been great on my Lenovo but this usb wlan stuff has been a pain.
I'm running Fedora 15 KDE on a Sony Vaio VPCS13V9E. No problems in connecting to the wlan. Today I upgraded the system. There was an upgrade for Network Manager. After the upgrade the system is not able to connect to the modem - router (Linksys WAG320N) any more. Network manager keeps on crashing and sends messages like "network disabled" or "connection failed". Kde demon is reporting errors too. I guess the new version of Network Manager is bugged, because before the upgrade it did work well ... (unbelievable!).
I have a Dell XPS M1330. I installed Fedora 10 on a separate partition and left Vista on the first. It was working just fine and for some reason all of the sudden it is not recognizing the Wireless controller. Vista is still working fine although I did get a couple of "WLAN controller has stopped working" errors. I suspect I may have a physical problem with the controller but I'm confused as to why Vista is still using it but Linux is not. The actual physicall "WIFI" light on the laptop does not even illuminate when I boot Linux. No wireless networks appear in the network list under Linux. Particularly since it WAS working fine for months...
My problem with UBUNTU is that I can not use acer-wmi because I get this ERROR :
Code:
... so I can not use the acer_wmi . But this is not my only Problem :
It is most likely caused of the missing " Firmware " / Driver for my WLAN Card ( Internal ) . Currently I use Ubuntu 10.10 but I tested 10.04 too before 10.10 and it found my Card but not the Button .
So I want to know if there is any solution for my problem .
If it is important :
I use an Acer eMachines e525 with Windows Vista Home Basic ( Pimped up ) and Wubi . I saw a lot of people with simmilar problems they have it as only boot option .
I updated Ubuntu to 10.04 after which I noticed the wireless indicator lights on my HP laptop were continually flashing between blue and orange and network performance seemed slow. I did some searching and found and implemented the following change to stop the flashing:
gksudo gedit /etc/modprobe.d/wlan.conf
Copy and paste the below line:
options iwlcore led_mode=1
Since making this change the wireless connection is shut off and I can;t get it to work at all. I first tried simply to remove the change to get back wher I was, but I can;t do that. Can sopmebopdy toell me at least how to get rid of this wlan,conf file ( it was created by the above command) so I can start over?
Coincidentally since making this change my Windows Vista OS fails to start because of errors attributed to a software or hardware change, of which there were none other than the Ubuntu wlan.conf change. . It may be unrelated but I am suspicious of the coincidence. I am running Vista and Ubuntu in a dual boot configuration and all ha run very well until I did the Ubuntu wlan.conf change.
I am now attempting a complete recovery of my Vista system, since it seems irreparably broken. Again coincidence or not?
(For the record, I have already read the other threads. Either they don't work for me or are too difficult.) My laptop is an Acer TravelMate 250. I have installed Ubuntu 10.10 (2.6.35-28 generic i686) after erasing Windows 7. At first, the usb wireless adapter worked. Then, I restarted the PC because of some updates and it didn't work anymore. In "edit connections" I find "Auto SpeedTouch8350DB" which is the wireless connection (on my sis's computer it works). When it tries to connect, I'm asked the password but it doesn't work.
very much like everybody i am also waiting for centos 5.3, because 5.2 could not sit on my notebook due to obvious driver issues. would anybody tell if centos 5.3 support my x3100 graphics card and bcm 4311 wlan card?
I have an HP Pavilion notebook with a Broadcom WLANcard that had been working very nicely in Fedora Core 10 until this evening, when I took my notebook to a conference room where there was no internet access. (I tried to connect to wireless networks, but there were none in the area, as I discovered.) am now unable to connect to my local (home) wireless network as the device is now non-existent . Can someone please walk me through the steps to fix this or re-install it (I have tried reinstalling broadcom-wl, but that didn't help). My lspci listing is reproduced below:
Code: 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03)
I have a desktop that has a d-link DWL-520 wireless card, which was working under Windoze. Today I installed Centos 5.4 on the system , which went cleanly. I then used Network Configuration to set up the wireless card. I specified to use DHCP, set the SSID and authentication password. When I tried to activate the card I get these error messages
Error for wireless request "Set Mode" (8B06): SET failed on device wlan0 ; Operation not supported. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0.
The hardware manager seems to have correctly identified the card and chipset, (Intersil Prism 2.5) and installed driver hostap_pci which came with the distro. This web site seems to suggest that this is the correct driver: [URL] searching forums I've found a few references to these errors, but they were from several years ago, and for different distros and cards. I did find a reference to using Network Manager to configure the card instead of Network Configuration. I started the NM service and configured a connection using it instead, but still no luck.
I patched my wireless driver in order to support packet injection. Using this tutorial:
- Install the Firmware:
Code:
- Create new directory:
Code:
- Now disconnect Internet and unload all your driver (use rmmod command)
- Move/copy the Compat-Wireless patched in /usr/src/drivers directory and unpack the drivers:
Code:
Blacklist the wl driver: (STA driver)
Code:
Currently I'm running Ubuntu 10.10, Kernel 2.5.35-29-generic. I have a Broadcom 4318 for my WLAN and a Broadcom 4401-B0 for my ethernet. I followed the tutorial and I managed to get packet injection working on my WLAN; however, my ethernet connection isn't working. I tried sudo modeprobe b44, but I get the following message:
