It's funny because about 10 minutes after I got back from BestBuy a customer service rep from Cisco called me to follow up on the call I put into them yesterday for one last round of troubleshooting. They were disappoint when I said I returned the E3000 and went with a different brand. It was $100 cheaper, so it'll be nice to get that put back on my Amex card in a few days.
Setup my PS3 and am about to setup my 360 and test it now. Just need to assign a static IP on it and forward a few ports first.
Already got a jump in connection performance on the PS3 when doing the Internet Connection Test from the XMB.
