Ubuntu: My WIFI connection randomly drops


My Wifi connections randomly stops working. And the only way to "bring it back", without a click on wifi icon, is to open the terminal and type sudo service network-manager restart then it's reconnecting to (same) wifi access point, and it's working again till next time.

I know that it's not a problem in my Router/Wifi AP, because I am using 3 different computers, and on other 2 it's working fine.

What can I do ?

This is report of sudo lshw -class network

I had the same issue, but my wireless is Realtek rather that Ralink. Nonetheless the fix is pretty much the same, the problem is caused by a driver issue.

Please see the below for instruction on how to install your wifi drivers.
