If cnet is the only site you are experiencing difficulties with then it's not on your end.Check the FORUM FEEDBACK,there are on going issues.
We have had a wireless network in our house for about 2 years now and had not had a problem, one day out of the blue the internet is going super slow, it took me about a minute th load cnet. I dont think i have a virus because i have run sweeps and nothing. I already unpluged it to see if that helped and nothing. any help would be very helpful (lol).
