After installing kernel upgrade from 3.2 to 3.5 wifi does not work. I have intel wireless. Wireless adapter isn't shown in network settings. How can I enable wifi?

There is a reason the mainline kernels are meant for debugging and testing purposes only. See the below question for more details -- it explicitly warns you may lose wireless:

Should I upgrade to the "mainline" kernels?

I recommend you go back to the official Ubuntu kernel. The mainline kernels, or kernels you build yourself are not supported and often result in problems with graphics and/or wireless. While the Intel wireless drivers are in-kernel, there is no guarantee they will always work on a non-official kernel.

If you were having problems that required you to try upgrading to a mainline kernel, please open a question about that problem and we can try to help you resolve it with the existing kernel.

I had this bug too. Try to find more info about your wifi driver with modinfo. In my case is modinfo brcmsmac. If that's the case, you can follow instructions from here to re compile the driver (isn't that difficult).

  • The question says "I have Intel wireless". brcmsmac and your link refer to Broadcom adapters, not Intel. – ish Jul 31 '12 at 21:38
