xfi gateway (xfinity modem/router) rebooting multiple times/day

My xfi  gateway (xfinity modem/router) reboots itself several times during the night and sometimes during the day. Rebooted twice tonight within 30min.  I am a late nighter and early riser so it really annoys me. Not all my apps restart themselves. I have manually hard booted router and laptop and moved gateway to another cable outlet. I have xfinity cable but I haven't used the TV box yet. I stream 24/7.

I have searched the forums and there are several posts about my problem and several solutions. It may well be my signal. I have outlets in two rooms and assume there is a splitter somewhere and I am going to put another one before the gateway. Could someone guide to what I should check next? I would like someone to come out and check my wiring. Maybe a separate line feeding the router?

Lenovo Yoga 131KB

Win10 64bit version 20H2tlet. 

xfinity/comcast modem and router

Start with the modem's signal stats. Perhaps they already are, or they are close to being out of spec and intermittently they go completely of spec. Try getting them here http://192.168.100.1 or here http://10.0.0.1 


Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

@EG  Thanks man.  While I dig that out have a look at this. I just bought this place. I think the orang is fiber? I know there's fiber to home here. I think my 5yr old niece could do a better job. The coax has been cut and left.

It looks like temporary coax cable. It goes into a filter or a grounding block (can't see it well) and then a 2-way coax splitter.

@EG Thanks for looking at that man. I'm somewhat just venting here LOL. The black coax is the original service cable. A local service provider ran the fiber. They just cut the coax and left it laying and didn't even secure the orange cable. I started to cut the coax off, but I'm gonna wait. And yeah the orange goes to an ?adapter? to the white coax which is split into two for my wired rooms. The also is blue network cable (cat5?)  which is very interesting depending on where it goes but it is not connected.

OK now I feel like an dope. I can't get logged on to the gateway. "admin" is the user but "password" is not correct. I don't think I changed it, I haven't even logged on to the gateway before. The login keeps locking me out after 3 tries.

If you hard reset it to factory defaults by pressing and holding in the recessed reset button on the rear for 30 seconds, the password will again become the default of password. You will lose any customized settings if you do that and they will need to be re-configured from scratch.

@EG Something told me you were gonna say that. I did customize the router when I installed. Give me a bit to think and look for my installation notes I took.

@EG Was thinking... If I reset the gateway it will clear the logs. So I will reset it and then wait for a few reboots then get the logs. Maybe a week or so. Should I post them here?

The reason I am hesitant is seems like every time I reset a device to factory defaults it is difficult to recover. I still have the same issue and now other problems. Any way I will. I wish there was a password reset from a wired device. If security is the concern, if someone can cable into my gateway, they could just as easily reset it. Just my opinion.

Post the signal stats as I requested earlier in this thread. There is no need to wait.

@EG Apparently this has fixed itself. I've looked back at my logs and reboot happens about 1/wk now. I can handle that. Thanks again for the help.

You're welcome but you never posted the signal stats so I can't advise if they are o/k or borderline. It could be a problem just waiting to surface again.
