Hello,

I have a Latitude E6400 on which I have been connecting to a private wireless at the home of the family with whom I am living.  Until two weeks ago (or so), I never had a problem with the connection.  Then it started to get a little spotty, and I wasn't able to connect every now and then.  I thought that it was just a problem with their signal, not my computer.  However, the signal there is fine--strong--but my computer refuses to connect to the internet anywhere (their house, other places with wireless networks/wireless hotspots).... In some places I have "local access," but when I open the browser, I only get an error message.

The wireless connection switch is on, and I've looked around online, but I can't figure out what is wrong with my computer or find any solutions to the problem....

I know very little about computers, but if anyone has any suggestions, I can answer questions and follow directions.  I am living in a foreign country for the next several months, and thus am unable to easily call Dell support.  Thank you in advance for any help!
