New to forum. I have several computers in my house online with my cable company as ISP, via a Belkin router. No problems getting online with any of the PC's, either hardwired or by wireless connection, except one PC which happens to be via an ethernet cable. Cannot get online at all either via internet explorer or by trying to log onto AOL--I am not sure if this is any internet explorer problem, since aol uses this as their browser, or something more intrinsic to the computer. I did a Norton virus scan, ad ware scan, checked my cable connections, ran a scan on the hard drive, checked the driver for the modem and all appears to be functioning but I cannot get online (needless to say, I am posting this from another PC). The only thing that seemed to work was running a system restore to a date about 10 days earlier; it got me back on line but a day or two later I was back into the same problem all over again. The unit in question is an HP pavilion a250y running Windows Xp. Anyone have any suggestions?
