Easy installation & start up once TWC loaded the modem's MAC address. It took about 5 minutes max and I was free of TWC's $10/month rental fee! Woo-woo! This modem is capable of much higher speeds than TWC's modem. I'm getting 36Mbps on my home Wifi from down in the basement. Typically I would only get 25-26 Mbps using the older TWC modem with the identical, WiFi setup. I'm happy as a clam!
