Q:

How do I speed up my Internet?

My Ubuntu machine's internet is relatively slow  in comparison to the rest of my family's windows machines which almost always have internet at full bars.(mine is normally 2 of 4)

A:

Moving closer to the WiFi access point may help.  If you are certain its not a WiFi issue I found setting my DNS to either Google DNS or OpenDNS made a difference in my case.
