I bought this modem hoping to gain some performance and to clear up some desk space. I was happy with the performance of the hardware that was plugged into the modem but the wifi performance was terrible. The biggest problem I experienced was with streaming Netflix through my PS3. The playpack would stop every 10 min. or less because of lost connection and then you would have to wait to rebuffer again before proceding. I returned the unit and bought the SURFboard SB6121 modem and hooked it to my belkin router. This worked great and I can stream HD content thru the PS3 with absoluty no issues.
What's great about it: Clears up desk space and you can hardwire more than one item directly into the modem
What's not so great: If your planning to use the WiFi feature
