I have some questions for you guys:
Do any of you guys have comcast internet that has a wired AND wireless connection?
What router do you use?
Was it provided by comcast?
I have a phone modem and a netgear 614 that they provide, but it severly lags when gaming and on wireless in general. (Speedtest says 30bps on my desktop and I get anywhere from 2-15 bps on my laptop and ps3.)
It might be your router or the laptop.
From the netgear model, it looks like the best it can do is 802.11g.
Does your laptop use 802.11 a/b/g/n?
