wireless doesn't work after upgrade from 11.04 to 11.10

[blubuzo]

I've upgraded my ubuntu from 11.04 to 11.10. After that, my wireless card wasn't recognized and no wireless options were shown in Network Manager. I have an intel wireless card and i suppose there is a problem with iwlagn

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the release candidate kernel versus the daily build. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[blubuzo (segudt)]

I'm using this as my main machine, does that cause instability?

You can boot back to your original kernel, using the grub menu, once you test the mainline kernel.

[blubuzo (segudt)]

I've used the latest 3.0.4 and 3.0.6 kernels, with no positive results

[blubuzo (segudt)]

tested latest 3.0.4 and 3.0.6 with same problems

[Tim Gardner (timg-tpi)]

This is simply bizarre. You should be running the iwl4965 driver, e.g.,

rtg@xps1710:~/proj/ubuntu-oneiric$ lsmod|grep iwl
iwl4965 132375 0
iwl_legacy 83487 1 iwl4965
mac80211 310872 2 iwl4965,iwl_legacy
cfg80211 199587 3 iwl4965,iwl_legacy,mac80211

yet it appears you have installed the iwlagn driver. Perhaps you could try:

sudo modprobe -r iwlagn
sudo modprobe iwl4965

I find wireless is working, it is just not initializing correctly with saved information like SSID & WPA2 keys (in my case). Once the information is provided, wifi does connect.

This is a major annoyance, however, because it means re-configuring wireless after every suspend.

[blubuzo (segudt)]

Hi, in my case the solution worked. I've added to my /etc/modules list and now the wireless card works :)

I don't know about the network list, but did you made the change permanent (added to modules) or are you using the two commands provided?

[blubuzo (segudt)]

The problem seems fixed for me, thank you Tim.

Marking invalid based on original reporter feedback.

Wireless still doesn't work for me after upgrade to 11.10.
