I did use Ubuntu 10.10 for a long time, and now I replaced it with Ubuntu 12.10, every thing works great, but I do have one little problem, which is with my wireless card.
On Ubuntu 10.10, it worked PERFECTLY, and it even worked better than in windows 7, so I was very happy with Ubuntu 10.10, but, like I said, after installing 12.10, my wireless card doesn't work any more, so I heard that KERNELS are the reason for that.
Are kernels the reason for my wireless not working now? If yes then please teach me how to remove my current kernels and install 10.10 kernels.
I went to -Additional Drivers- and i found something very weird i took picture and this is what it look like
"apply changes" Button NOT active so i can't install driver :(
anyway... my Wireless card is WL-138g v2 (remember on Ubuntu 10.10 it was WORKING 100% normally and FREE i did NOT pay for it driver)
so... now what shall i do ? it is saying in picture // Using Non-Free firmware for linux kernel drivers from linux-firmware-nonfree (proprietary) //
BTW i did "rfkill list" but NO-thing appear under that command.
