I made a big mistake after trying to install wireless drivers through Windows Wireless drivers on Linux Mint 15

The Wireless interface was working properly before that, but it was working on wi-fi G 54 Mbit/s standard instead of N on 150-300 Mbit/s.
Here is some output which I think it can be helpful for resolving the issue:
