    This modem is doing well so far. No complaints and haven't had to restart much at all. Once Comcast gets gigabit service, I am hoping it will perform even better.

    Ok modem. I get about 800-900 Mbps during speed tests on my gig internet plan so this modem is doing the job. I think I’m limited by my isp. If you want more LAN ports you can get an adapter or upgrade to another modem. I’m ok with one LAN going to my router than my router has more so I can hard wire Ethernet from there.

    After having so many problems with my WiFi, I decided to change providers. Instead of paying monthly charges to the new provider I purchased the equipment as guided by the provider and I am very satisfied with its' performance. It works well with my new Google WiFi equipment and I am once again pleased with using my Wifi.
