internet connected, but no access

I was playing a WoW when out of nowhere i hit a bunch of lag and i was booted off the server, my computer popped up w/ the limited or no connectivity message, however it also showed that i was connected w/ excellent signal strength. I live in a house w/ another guy and he's accessing the internet fine. What should i do??

Thanks!

Probably overloaded connection.

I would recommend to "port" the connection, to avoid overload.

I think it's malware. I'm WOW player too
