Internet intermittent, from overnight, restart modem each morning 5 am
I have Xfinity internet (800 Gbps plan), customer equipment (Arris SB8200). Usually no connection overnight, upstream / downstream lights amber on cable modem (downstream usually amber/yellow or blue, but always lit). I power cycle modem each morning at 5 am, then reconnects, power off router, then power on router. All then works. Have been doing this routine since approximately 2/10/2024. Before then was more available without cycling.
I have reviewed internet connection troubleshooting:
1) am unable to get response on http://192.168.100.1 or here http://10.0.0.1. I need someone from customer service to obtain for me. I have no idea of *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers. In July/August 2023, (I believe) Xfinity checked due to local area internet connectivity issue and informed me downstream/snr/upstream were within range.
2) I am aware of the limitation of this model only being able to support approx 900 Gbps or less.
3) For speed I am satisfied with PC/iphone to router of 400-500 Gbps usually.
Please advise.

Are you getting an error message when you try to browse to those two addresses ?

Have you tried hard resetting the 8200 to factory defaults by pressing and holding in the recessed reset button on the rear for 25-30 seconds. This can sometimes clear up some weird behavior issues. YMMV. Then use http://192.168.100.1 with a computer that is hardwired directly to it.

As of Saturday, February 24, 2024, I am no longer having the intermittent connection issues. Bandwidth does vary from 300 Mbps - 700 Mbps but is overwise stable. I will reply to the users who tried to assist below.
