Its all about the bottle neck. It doesn't matter if you had a Billion Mbps transfer rate to the router, if your connection rate from the modem to XBL is only 5 or 10Mbps, it would make anything worse. And given the transfer-rate controls the way the data is transferred, it could actually make it worst. If your streaming from your PC to the Xbox, then yes, look into what Furry is talking about. If your just trying to get a better connection to Xbox live, go wired. And go wired to the modem first. Your not going to get any faster then that. Period. Unless your having problems at the ISP level or you can upgrade your service with them.
