    After updating, wireless no longer shows

    I recently updated to Elementary OS 0.2 and after the update my wireless just cut out and doesn't show anymore. I have an HP Pavilion g7.

    lo no wireless extensions.




    I figured it was my wireless driver, so I followed the tutorial here:

    but after I restarted still nothing happened. In my network center it doesn't show any network connections. Please, any help is much appreciated.

    Re: After updating, wireless no longer shows

    Thank you the wireless works now. However, every time I open an application while connected to wireless, I get a kernel panic. Could this possibly be due to compiling an old kernel with the other tutorial I used?

    Why did you install the mainline kernel? Any possibility for kernel 3.5 regularly?
