I have been having strange connection issues lately on my Desktop. When I check the network, it says I'm connected to the internet, but when I try to access a webpage or connect to the net in anyway it times out. Troubleshooting the network always results in a "Cannot connect to DNS" error, and the connection error sign in the taskbar only appears when troubleshooting or connecting to the internet. However, I've noticed that I get small windows of internet access if I unplug from the router and then replug back in. Sometimes it only lasts a few seconds or a few minutes. But the weirdest thing is that I can maintain a stable connection with programs that require constant internet access. For example, MSN Messenger. I initially can not sign in to MSN Messenger, but in the small window of internet time I can. Eventually, when the problems return, I can still keep a connection with MSN Messenger, but still can't access webpages or establish a connection with programs. It's the same thing with online games, Steam, and even Teamspeak. So far, I've tried resetting the router, ipconfig /release and /renew, /flushdns, and updating network drivers, but nothing has changed. Oh, I should also mention that this problem is only happening on my computer. Everyone else on the network isn't having a problem. I also tried scanning with AVG and turned up nothing.
