Ubuntu Networking :: Wireless Gone After Kernel Upgrade?
Jan 20, 2010
I am writing this using the 2.6.31-17 generic kernel after rebooting and selecting NOT to use the 2.6.31-18 kernel which was just installed. The newer kernel would not recognize/activate my Atheros AR2418 wireless adapter and, when I connected to the ethernet and did updates, there were no hardware drivers available. I haven't needed proprietary drivers since I upgraded to 9.04 and 9.10 works fine with older kernel.

I upgraded from kernel-2.6.38.6-27.fc15.x86_64 to kernel-2.6.38.7-30.fc15.x86_64. After the upgrade I no longer have a wireless interface in Network Management. I have a broadcom BCM4312, booting the previous kernel solves this problem.

Recently, I installed a fresh 64bit Lucid Lynx on my Lenovo B450 laptop (previously on Mint8 64bit, based on Karmic). It's been really nice and speedy except for one thing - USB transfers to thumb drives and external hard drives were really slow (just like in the older Ubuntu releases). I had found some forum discussions on a fix to this by way of a kernel upgrade so I decided to go for it.
Went ahead and downloaded the kernel DEBs from [URL] and installed them. Voila! USB speed issue was fixed! Everything else seemed to work fine, except for some minor troubles with burning CDs and DVDs (I think I need to upgrade the drive's firmware - pretty bad situation as the update only runs on Windows).
However, the one 'bug' or 'annoyance' I noticed straight away was that my wireless wouldn't autostart after booting into the OS with the new 2.6.34-020634-generic (x86_64) kernel. I'd have to right-click on the NetworkManager icon on the notification tray and left-click '[ ] Enable Wireless' to flag the checkbox and my wireless would come right up and work ok (WPA2 at home, WEP at the office). Not a major problem, but this has been pretty irritating to say the least.

This is my first post here. I'm using Opensuse 11.2 (Gnome)and the inbuilt kernel is 2.6.31.xx. My laptop is having bcm4312 (14e4 : 4315 id)chipset for wireless. (0e:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) 0e:00.0 0280: 14e4:4315 (rev 01) ) I have read multiple times here in some threads that this kernel will require Broadcom-wl drivers(Tried ,No success with this) And If I want to use b43 drivers , then I need to go for the 2.6.32 kernel (stable one from this release). I've done the same exactly given in some other link -
Steps-
make mrproper
make menuconfig
make dep
make clean
make bzImage
make modules
make modules_install
After rebooting it's not showing anything new.Just the boot menu with the older one. Experts, Kindly let me know what I'm missing?

I have changed kernel to 2.6.33. After that ifconfig command shows only my ethernet card, wireless card have disappeared. What is wrong. In the old kernel everything works fine. I am sure that i have installed wi-fi stuff with kernel.

Testing distribution. Installed Linux 3.0 but left 2.6.32 on as backup. When I boot into the old kernel, wireless mostly works OK, but never when I boot with the new kernel.
Results of dmesg|grep wlan0 on 2.6:
[ 22.005102] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.196774] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.644779] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 30.688053] wlan0: direct probe to AP 00:19:5b:06:9f:ba (try 1)
[ 30.694053] wlan0: direct probe responded
[Code]...
Noticing the Access Point looked like it needed the MAC address, I ran iwconfig wlan0 ap <MACADDRESS> and sometimes it will work, and wicd can connect to the access point. But sometimes the command fails to run.

No wireless after upgrading to linux kernel 3.0 in opensuse 11.4. I'm using Kde and gnome 3, everything was working fine under the 2.6.39 kernel, but now both only detects my wired connection. Any help resolving this would be greatly appreciated. I have a Netgear WNDA3100 adapter that uses the Atheros drivers. It also is no longer detected in my Fedora 15 after upgrading the kernel, but it still works in Mint 11 with the 2.6.38.8 kernel.

I have just built a PC based around an i7-860 and Asus P7P55D mobo. It was running fine until the big update that happened today and now the internet is like treacle. I did the same update to my other (different hardware) PC and all is fine with it.
When I load the earlier 2.6.32-21 kernel instead of 2.6.32-24, the new system works as it should and the Internet is very fast. This suggests to me that the kernel update is the problem, most likely the NIC driver. This motherboard has a Realtek 8112L NIC fitted.
Has anyone else had this issue and what is the best way around it other than loading the older kernel and hoping that the next update will fix it?

I hate kernel upgrades, at least on my laptop. Every time I upgrade, I have to recompile the driver for my Linksys WUSB600N adapter or it doesn't work. Usually, this is no problem, as I have the driver saved in a .tar file and all I have to do is 'make' and 'make install' and it works. BUT... This time, I tried that, and I get this:
Code:
doug@dh-laptop:~/LOCAL/Software/RT3572_Linux_STA_v2.4.0.2$ make
make -C tools
make[1]: Entering directory `/home/doug/LOCAL/Software/RT3572_Linux_STA_v2.4.0.2/tools'
gcc -g bin2h.c -o bin2h
make[1]: Leaving directory `/home/doug/LOCAL/Software/RT3572_Linux_STA_v2.4.0.2/tools'
/home/doug/LOCAL/Software/RT3572_Linux_STA_v2.4.0.2/tools/bin2h

after upgrading to kernel 2.6.34.6 I have two issues which I don't know how to solve. First and more important is an issue with boot process. The boot is ok until it is supposed to switch to gnome desktop. Then suddenly the graphics become a weird line pattern with no discernible features. Only a rectangle which moves upon moving the mouse. This can be resolved by switching to a console, logging in there and killing the gnome-session. (with kill -9) Then, instantly the desktop appears as usual, the background is loaded, the panels come up and all seems well.
I have no clue what causes this. I thought there's a display driver problem but since I can actually get back to the normal graphics state I'm confused. Also glxinfo says:
Code:
[Me@Plato ~]$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI R600 (RV620 95C4) 20090101 TCL DRI2
Secondly the nm-applet doesn't work until restartet. Normally I expect to see an authorization request window, prompting for my passwd to start wireless networking, and the little icon in the panel. Both don't show up until I kill the nm-applet process and restart it. After I do this everything is back to normal and working as expected.
I assume if problem one is solved, two won't be a problem anymore because I expect the password dialog hidden somewhere in the background when the graphics is all garbled..
Edit: Failed to mention thath my graphics card is ATI3470 as shown in the signature...

Im on 9.04 and i upgraded to the latest kernel. Pretty much a default .config for a kernel few things here and there removed. When i boot into the kernel and go to connect to the wifi it shows enable wireless grayed out and enable networking checked.

I recently upgraded the kernel in 9.10 to fix a problem of no sound on my laptop but this killed wireless However I could still boot into the previous kernel to use wireless (albeit without sound). I found a fix for this problem on the forums: [URL]... but It didn't work so well in my case. Specifically after executing the command

If anyone knows how to undo the rmmod dell_laptop command or has some insight into what I might be able to do let me know

A quick note for other frustrated Ubuntu users out there. I have a D-Link DWA-510 PCI wireless card (RT61) that just stopped working. After wasting hours searching posts and asking for help, I've determined that there's a problem in the latest Kernel to be rolled out.
I have now installed StartUp-Manager, and used it to boot into the old 2.6.31-22 kernel still on the machine and, hey presto, wireless is working again. It seems like the simplest fix by far.

How can I get information similar to proc/net/wireless but for more than just the wireless router I'm connected to. I know there has to be a way because when I'm disconnected from all routers the network manager shows signal strength of all available routers.

I'v tried to uninstall and reinstall wubbi 4 times already. Before the OS even start up it says that it cannot find the wireless kernel and then it boots me up into that start up with the *configuration wizard* and that fails as well and asks me to reboot.How can i get my wireless transfered to Ubuntu without using a flash drive or CD? I thought that Ubuntu would automatically detect my wireless but i see no options as such.

Anyone know of a good guide to use reinstalling a wireless driver using ndiswrapper after a kernel updates? I seem to have to do it a lot, and I'm looking for some good directions.

I was able to successfully install the drivers on the generic kernel, but I seem to be having a problem getting it done on the real time kernel I downloaded via the Ubuntu Software Center. Here's what shows up when I type in 'make' at the command line:

NOTE: My upgrade wasn't smooth. Now everything is extremely slow. However if I boot from the disc to try without installing, the connection problem is still there. There is an exclamation mark on the connection applet, right clicking shows that Enable Wireless is unchecked and unclickable. I've included outputs of common network commands which might prove to be useful.
Code:
[~] ifconfig
eth0 Link encap:Ethernet HWaddr 00:1e:33:60:f0:3c
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

I have a thinkpad using the iwl3945 driver (Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks).
This worked flawless until I upgraded to 10.04. Now after a while my connection drops. Syslog is appended.
May 10 20:16:04 gimli NetworkManager: <info> Activation (wlan0) starting connection 'Auto my-network'
May 10 20:16:04 gimli NetworkManager: <info> (wlan0): device state change: 3 -> 4 (reason 0)

I upgraded from 9.x to 10.10. Under 9.x my wireless usb dongle worked correctly. After upgrade it does not. I checked the dongle on another machine and it works correctly. I inserted a usb memory stick and the system found it as a drive correctly. I assume from this that both the dongle and usb port are ok. The wireless device is a D-Link G122 A2 which is on the supported list (it ran out of the box on 9.x). The link light did not even come on. So I installed ndiswrapper and the windows D-Link driver (note that this was not needed in 9.x). Now the link light comes on and the wireless router is found but the unit will still not connect.
The log file entries on dongle insertion are as follows:
It appears that the problem is with wlan0 not being ready. If this is the case how do I make it ready?

I have an out-of-the-box Belkin G wireless router. I also have a Linksys USB adapter on a particular box. When I run the Ubuntu 8.10 live CD on that box I can see the router's SSID, I supply the password, and all is fine. I think that rules out any problems with the router or the ISP.
When I run the Ubuntu 10.04 on that same box I can still see the SSID but when I try to connect to it the DHCP fails. Checking the system logs I see the DHCPDISCOVER entries but no corresponding DHCPOFFER responses. So this seems on the surface to be a DHCP problem. To get around this I tried to edit the connection to use manually supplied settings. On the 8.10 system I supplied:
Code:
IP=192.168.2.200,
Netmask=255.255.255.0
Gateway=192.168.2.1
DNS=192.168.2.1
and again all worked just fine. But when I supply the same values to the 10.04 system it does not work. Even attempts to ping the router (192.168.2.1) fail. So if this fails then perhaps the problem is more fundamental than DHCP? I have tried searching the net for quite a while and found a number of similar problems, but clear solutions seem to be lacking (or I haven't come across them). One common suggestion is to blacklist the ipv6 module. I tried that and it seemed to have no effect. Since this worked so well in 8.10 and doesn't work in 10.04.

After upgrading from 10.10 I now have no wireless activity. Everything was great with 10.10 by the way. I have a dell inspiron 1520 with a Dell wireless 1390 card and broadcom 440x integrated controller.
I have seen other threads that are to complicated for me to follow, I would just love for my wireless to work and can follow basic instructions if anyone can help.
I just spent the last 6 days in Florida on business while the tornadoes ravaged my homeland in Alabama and turned alot of people on to Ubuntu. Everyone that walked past my laptop wanted to play with it and asked what it was.

I just updated my work laptop to Natty: perfect. My home server: perfect. My oldish home laptop: no more wireless. [I use wicd instead of Knetwork (or whatever it's called) because I want a permanent connection no matter the user]
I have a D-Link DWA-645. I get the whole stage: connecting, authenticating, etc... and bad password at the end. The password is correct (hasn't changed during upgrade). I also tried disabling WPA and it still won't connect. That's wlan2.
I also tried with an older PCMCIA card that _used_ to work on ubuntu 9, but stopped on version 10: a D-LinkDWL-G650. It doesn't even show up as wlan0 as it used to. I also tried with a USB-wifi DWL-G122 which has always worked on every version of Ubuntu [I don't normally use it because it's not practical on a laptop]. I see it as wlan1, but same thing: won't connect. Note that like with wlan2 I can scan for networks and see several around. For instance:
Code:
$ iwconfig
IEEE 802.11bg
ESSID: off/any
Mode: managed
Access point: not associated
Tx power: 20 dBm
Retry long limit: 7
[Code]...
[Edit]
Some more info: the access point works fine, I can connect with another device. The driver in use by Ubuntu is ath9k. Using KnetworkManager instead of wicd doesn't change anything.

My Intel Corporation WiFi Link 1000 Series wireless card stopped working yesterday after I did an update via Update Manager.After the upgrade, wireless is disabled and the option to enable it in Network Manager is grayed out. I thought that it might be the new kernel, but changing back to the old kernel I still have the problem.

I just want to enable my wireless network card... how do I do that? It worked perfectly in Jaunty and it also worked when Jaunty was upgraded to Karmic, but in a fresh install of Karmic it is displayed as DISABLED:
sudo lshw | grep network:
*-network:0 DISABLED
I know this is not a bug in any kernel or anything. I now have Karmic on two identical laptops (Fujitsu Siemens AMILO, rt2500pci chipset) with the same kernel (2.6.31-22-generic). Wireless is enabled on one, disabled on the other. This is wearing me out... I am on the verge of buying Windows 7...

I have this weird issue which only appears when I am using 64 bit Ubuntu. Every now and then my laptop seems to go into a kernel panic (system unresponsive, numlock and scrollock lights flash repetitively) only when I am using the broadcom wireless. I can connect to my wireless router and use the internet and local network, but eventually, kablamo, crash, bang, boom. The only way out of the crash is to power off completely. After repowering, the wireless network is fine until the next crash. There does not seem to be a pattern or time period to cause this crash either. I have purged network manager(which I couldn't get to use my wireless) and am using wicd, which allows me to connect wirelessly.
Here is the details of my system:
Dell inspiron 1520
lspci (snipped)
0c:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

I just upgraded the kernel on my Ubuntu laptop from 2.6.32-24-generic to 2.6.32-25-generic (using the update manager under gnome). After the update, the wireless network controller shows up as UNCLAIMED when I do lshw -C network.When I try to install the driver with the commands sudo modprobe lib80211 sudo insmod wl.ko
i get this error message: insmod: error inserting 'wl.ko': -1 Invalid module format
I have compiled the driver using the 2.6.32-24 kernel. Do I have to re-compile with the new kernel?I'm a unix user, but not a kernel hacker, so I'm wondering if I will run into problems every time I get a kernel update? Or is this problem an exception?

I am having some issues getting the broadcom sta driver installed on Kernels 2.6.36 up through 2.6.38.
Before I continue, I'll list my specs
Release: Xubuntu 10.04.2 LTS (64-Bit)
Wireless Card: Broadcom BCM4328
Kernel: 2.6.38-x (Any version), and 2.6.36 and above
EDIT: Yes! Yes! I got it to work, for those that are having issues, install this packages. Disregard that it says that there is an older version available in a software. The bcmwl-kernel-source for Natty works on Lucid![URL]... Install one of these and check your Hardware Drivers, they will probably say that the Broadcom STA driver is installed but not in use. If you then proceed to restart it should be up and running, this way you can use kernels 2.6.36+ and still use the Broadcom STA driver!
