A few of you have been witness to my connection problems, especially to Aion, the past couple weeks. It seems part of the solution was an upgrade to my cable modem. I went out and bought one and just had them (Comcast) provision it over the phone. Took about 5 minutes. It's fast, stable, and can handle DOCSIS 3.0 cable data standards (up to 150 Mbps).
