Suddenly, I cannot get out through my laptop.  I was on the Internet the night before, and the next morning I was not able to connect to my network.  I have tried several different things, including setting up a new router, thinking that it could be the router.  That did not work.  I got some kind of message like, "cannot connect to the Internet." I can connect directly to the modem, and that works fine.  I am going to try to connect using a different wireless network tomorrow, but I am looking for more suggestions about what could be wrong.  I have an Inspiron E1505, using XP with a Linksys G router.  Any help would be appreciated.  Thanks.
