we just recently upgraded from Rogers Extreme to Extreme Plus. This required a new modem that's has a router built into it. We have that connected to our other router which is much better quality. Now we have the router disabled but that's only the WIFI part. I don't know if it's the entire thing or if it's even possible. My roomie has to reboot the non rogers (Asus RT-N16) router for my connection with the net to be stable. I can download it seems normally but when I try to play World of Warcraft and I'm getting kicked left right and center. I go on to the neighbors wifi and I'm stable. Not a single DC. I switch back to ours and it's DC after DC.

I even tried flushing my DNS which did not help at either.. Suggestions ?
