I placed this piece of excrement in the round file that Comcast almost forces us to use (returned it), and went out and bought my own modem for $60 on 7/25/2014. I haven't had any drops, lag, jitters, latency, and I am now getting the bandwidth that I’ve been paying for since since 12/01/2013. Fix your excrement Comcast!!!

I'm having the same issues, my xfinity modem is connected to my Netgear Nighthawk X6 AC3200 Tri-Band WiFi Router 802.11ac Tri-Band Gigabit (R8000) ( www.netgear.com/R8000) 3 rooms over, in a single story house. with the Nighthawk i have full bars at all times, but my internet connection drops every few min for some reason. Comcast suport says it is my Nighthawk, but i took it with me to work and tested it out and it works flawlessly over a distance 3 times what i have here. So i know it's not my router. i just wished that comcast would get rid of ARRIS and either go with Cisco or Netgear, then all our issues would go bye-bye. With six high-performance antennas and three network bands, one 2.4GHz and two 5GHz, the Nighthawk X6 delivers the industry's fastest combined WiFi speed, up to 3.2 Gbps* (1300+1300+600 Mbps*). It balances the network load to ensure the best WiFi performance for each device and deliver the maximum wireless range available today.
