I'm pretty new to Ubuntu, but I previously had Ubuntu 11.10 on my Dell Inspiron 1545. After recently performing a system upgrade to version 12.04, I have been having trouble with my wireless connection. I have been googling my specific problems looking for an answer and have tried some things. Here are some outputs I've seen can be relevant:

A connection is made, but when I open firefox the display page that says "Server Not Found" usually appears. Sometimes after connecting the browser will work properly for about a minute and then trying to view new web pages just gives me the "Server Not Found" display. Thanks for answering and any help you may be able to provide me.
