Router continuously drops signal for macbook, apple tv and iphone. Android device fares better - signal is generally fine on Windows laptop.
I have contacted Xfinity support numerous times via phone. They reset the signal, see that its working, and think the problem is solved. Sometimes it works for a week or so - then WiFi starts dropping again.
Router and download speed are below:
Router - Technicolor CGM4140COM | Model number: CGM4140COM
Download Speed - Up to 1000 Mbps
If you are not using any Xfi Pods, you can try separating the 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;
