Things to try...
Power off the isp modem/router and your wireless router(if any). Wait 30 seconds, then turn on the ISP modem/router first, then wait 15 seconds and then turn on the wireless router.
Restart your computer and try to connect. Anything?
Try downloading and running WinSock XP Fix
. If you have to download and put on a flash drive, that will work.
Since I don't know if you have a 64-bit system or not, if you do, there are three versions of Internet Explorer. Start, in search, type, Internet. Use the Version that does not have (64-bit) after it. Internet Explorer (64-bit) does not support flash player.
Open Internet Explorer, click on tools, manage add-ons, enable or disable add-ons. Disable all the add-ons. Close Internet Explorer. Wait 30 seconds and then open Internet Explorer. Anything?
Did you try using Mozilla Firefox
