I use Debian 8 and tonight I tried to switch between the integrated wifi and an wifi usb key using online tutorial. It worked. I did this just to see if wireless connection was better, but it isn't.
Now I would like to switch back to my integrated wifi... I'm using an Acer Aspire 7715. I used "modprobe mt7601Usta" as last command to install/use the wifi usb key, but how can I switch/reinstall (to) my integrated wifi now ? I tried to find the name of my wifi module, using "sudo lshw -C network". I got "AR928X" as wireless product.
