Re: My ping in games is around 800!
I have a question. If you disconnect your brother's PC from the router, does your ping time drop back down?
If so, try updating the NIC drivers on his machine. Scan for spyware and viruses and make sure it is clean. The machine may be storming the router with packets causing network traffic and bringing your ping time up.
