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.

Yes, I will.  I have not reviewed the page yet.  Just for information coax connects to cable modem (Xfinity supplied), cat 7 from cable modem to Linksys 4200 Velop.  

Thanks for taking the time to respond.

user_noname,

I did try this by using a wireless connection from desktop, all I am getting is a connection timeout. I dont receive a login page.  

I then did a modem restart in the Xfinity app and entered 192.168.0.1 again and it is receiving a connection timeout also.

So in either attempt I fail on step 2 in the article as I am not reaching the modem.

((Correction to my note above it is not Xfinity supplied it is the purchased SB8200, trying to do too many things at once.))

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

I tried that but was still unable to get to the Login page.  Like the article states, I wonder if has to do with the firmware version.  On my label the default firmware is not indicated.

At this point, I am withdrawing this posting as I am no longer having the issue.

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.

I am no longer having intermittent issues.  I will try the solution you offered when I have time to investigate further.  I feel if I could get to the login page it would be more straightforward.  In my original post, I indicated Gbps it should be Mbps obviously, sorry for the confusion.

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.
