I have 2 computers hooked up to my router after a while my main computer cannot connect to the internet but but my all of my games stays connected online and if their was something open before the problem it will stay up. After a little while I can connect to the internet again. After a while of being able to connect I can't connect anymore. Dunno whats wrong I have replaced the router, the ethernet cables, I can still ping every PC on my LAN. I tried calling my ISP but they just told me that it was either the ethernet cable or the router.
