I have a Studio 1557 laptop (purchased in late December 2009) that all of a sudden has lost wireless connection to the internet.  Went to use it last night (Thursday) for normal use and no wireless connection at all.  Before this issue, there were no problems connecting thru wireless at all...in fact used it Wednesday evening for work/surfing and no problems whatsoever.  We are using a Linksys 160N router...have 2 other computers and 2 iPod Touches that are connecting just fine, absolutely no problems.  It can connect thru a wired connection with no problems but nothing thru wireless...this is a fairly new router, about 10 days old, but haven't had any issues with it since set-up.

Wanted to see if there might be any suggestions or thoughts before I delve into this over the weekend...didn't have much of a chance to do anything about this last night or this morning.  I really don't want to bother calling Dell Support either...as that has never been a positive experience in the past.

Thanks for any possible help...JL
