I went to a coffee wifi place and returned home and began having having problems connecting to my Linksys. I have gone through all of the directions, relisted my ip address and key #, and yet I cannot connect to Mozilla, Comcast, Explorer, or get help from Toshiba or Circuit City. They say it is a soft ware problem and I can't find it. Does anyone have ideas?
