mrsd...is his computer made by sony? you don't have to answer...but if it is..any part of it...att&t has a compatabilty problem. there are fixes for it, but the yahoo type of software that att&t uses will cause fatal errors and eventually fry it.
we can take this to pm if you want.
oh.....att&t has new upgraded routers. if that is the problem, they should give you a new one. i have the model numbers for the old and the new.
dang..i'm sorry this is all happening.
