I downloaded and installed a driver for my wireless usb dongle as it wasn't detected by linux (KDE). I wasn't very sure which model it was but apparently it is a Ralink RT2870 (Brand name IPTime N150UA). I downloaded the driver, patched a file to make it compatible with my new kernel version (3 and above) following this page and finally installed it like shown in the page. Then My wifi dongle was detected and I could connect to the network. The problem is, as soon as I do ssh or open the router's webpage my whole computer freezes and I have to shut it down. Now I want to delete this driver, I searched on internet but couldn't find anything helpful. When I run lshw I get for my wireless driver:
description: Wireless interface
physical id: 1
logical name: ra0
capabilities: ethernet physical wireless
configuration: broadcast=yes driver=RALINK WLAN ip=192.168.1.8 multicast=yes wireless=Ralink STA
That is a very weird driver name with a space in the middle. I can't even follow some tutorials about how to get more information about a driver because when I input RALINK WLAN it thinks it is two different driver names. What should I do?
