I have this strange problem where for no reason what so ever I lose my internet connection and IE7 will not load any web pages. To fix the problem I have to reboot.
Its not my router as I still have a solid connection to the internet via wireless from my laptop.

It will happen all of a sudden and I havent been able to pinpoint it to anything in particular that Ive done. I have good Anti virus and spyware protection as well.

Any suggestions??
