I have installed Ubuntu 12.04 LTS and my Airlive WL1700USB wireless card connects ok to access points, but there are big variations in speed. Sometimes it is 200Kb/s then again only 10b/s and so on. I'm using college internet with no key set on AP (open connection).
They have 10Mb/s speed and on win7 my internet is very fast but on Ubuntu it just doesn't work correctly. I tried it at home too and same problem.
Could it be a driver problem?
