I'm having troubles with my internet connection in ubuntu right now. Well, a few actually.
First, when I compare my speeds between ubuntu and Windows, I'm getting double my link speed on Windows than on ubuntu.
Second, my internet connection periodically drops. Usually when I'm downloading a large file or putting a large load on my connection. I can't connect to the internet for a few seconds and then my connection just drops and tries to reconnect (which is does after a few seconds).
I've tried a few fixes I've found around Google but none of them have helped me. My wired connection is perfectly fine but my router is in a place where I can't use wired as my default connection. My wireless connection is the one with the problems.
