I recently decided to make the plunge and install ubuntu 11.10 (32 bit) on my desktop. All went smoothly except for one bug: I couldn’t get Internet.
I use a wireless USB stick by edimax (it is called IEEE802.11b/g/n nano USB adapter or also EW-7811Un). The problem was that Ubuntu seems to be able to use the USB to see the networks around me, but when I tried to connect to my network (either when the router had the password on or off) – it just kept trying and failing to connect.
This is apparently a known bug which can be resolved after following some good leads from ubuntuforums (thanks the user “praseodym” for your help) and askubuntu (thank you user Engels Peralta for your help).
Bellow are the steps I needed to take in order to solve the problem in the smoothest fashion – I hope others might benefit from it in the future.
