Random router reboots

I'm on a 1.2 gig plan and my router was shipped, new, to me less than a month ago.  Speeds are fantastic, but in the last week or two it's been randomly rebooting, which is a pain.  I haven't yet found a pattern to the reboots (time of day, uptime, etc), but when it comes back, the connection time to the Xfinity network is definitely starting at 0h 0m 0s.  

Logging on the device is so limited that I cannot do substantial troubleshooting.  Below are the connection metrics shortly after the latest reboot:

The upstream power is borderline high and it may be intermittently fluctuating even higher to out-of-spec levels. The downstream power is on the weak side as well. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In an effort to try to obtain better connectivity / more wiggle room, check to see if there are any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage from Home Depot, Target, Wal-Mart, etc. Splitters should be swapped with known to be good / new ones to test.

Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Good luck !

It's been very easy for me to avoid looking into this in more detail and to just start swearing at it when it resets, but I did just move the router to a different location in the house, closer to the house feed.  I'll see if I can identify the cable routing and any splitters, eventually, but at a glance, here are the metrics at the new location.  The connection speed is fantastic, clocking 1298 Mbps down and 41 up through speedtest.net.

It's a bit better but the upstream power is still marginal. Not much wiggle room there.

I had to step out for a few hours, but as I look now, the uptime is 1h 50m, so it clearly reset.

Guess I'll have to actually dig into this.

Please revisit my earlier *things to try* post. If it turns out that there is nothing more that can be done to improve the connection quality, then you'll need a tech visit as stated. 


Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it up to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.


Good luck !

Appreciate the input.  I'll definitely be working through your post.  Just need to carve out some time.

Ok, so I checked the external setup.  Looking past a lot of "legacy" cabling, the current setup seems to be the lead to the house, run through a multi-room filter, a 12ish inch output from that to a 3-way SV-3BG Commscope splitter.  Each output on the splitter says -5.5dB.

The room I moved my router to yesterday was the closest, most direct connection.  However, as I have no need for coax connections in any other room, I took the splitter out of the sequence and took the cable to that room and ran it directly into the filter.  I don't know if the filter can come off if we're not using multi-room, but was reluctant to try it as it say, pretty clearly, do not remove.  Obviously that's subjective, but input on this would be great.

I can't tell the quality of the cable from there to the room.  It's been painted over and I'm not seeing any writing on the jacket.  It appears to be a heavier grade than some of the older, unused coax around the house.

I've reset my router and here's what I'm getting now.

Everything is much better now / well within spec. Is there a make and model number on the "multi-room filter" ? The bottom line is to live with it for a while now and see if the problem is gone.

It seems to be an MoCA POE filter.  Here's an amazon link to one which looks pretty much the same, but may not be the exact part number.  (My photo makes it hard for me to get the exact part and it's dark, so I'll have to take a better photo tomorrow.)

https://www.amazon.com/GLP-1G70CWWS-Filter-Eliminate-Multi-Room-Interference/dp/B08HJ4F4D4

The bad news is, even with the improved numbers, the connection has reset several times in the last 30 hours.  Sigh.

I can remove it, but not sure whether that'll do much.  I can also test it right at the line to the house, removing the cable into the room.  Not confident of either, but those are the obvious troubleshooting steps before I have a tech come out.

Try doing both for a test. But put the filter back afterwards, or replace it if it appears to be malfunctioning.

Sorry, took me a while to get around to this.  

I've done several tests.  The upstream on all of them seemed to be the same across the board, at 42.3, 42.3, 42.8, 43.3, 43.3 and 43.3 dBmV.

The downstream on channel 41 varied based on the conditions.  The SNR was 39.2 or 39.3 consistently.  The power broke down like this:

Upstairs, filtered:  4.4 dBmV

Upstairs, unfiltered: 5.2 dBmV

Directly on the line, filtered: 5.7 dBmV

Directly on the line, unfiltered: 6.0 dBmV

So clearly I've got some reduction on the line running upstairs and clearly the filter has an impact as well.

Right now I'm setup with Upstairs, unfiltered at 5.2.  I don't especially want to run for any length on the direct connection as that involves leaving hardware outside, or wrangling with windows and screens.  (Though I CAN do this if we get to that point.)

The filter in question has a sticker on it which says "Required for Multi-room DVR - Do Not Remove".  I don't have any DVR, so I don't think I really need that.  The engraved coding on the side says:

GLP-1G70CWWS

PPC 3321A

Anything after the S on the first line will be hidden by the sticker.  

So my plan is to run on the 5.2 dBmV connection for a bit to see how it behaves.  I'll then setup for a direct connection at 6.0 dBmV.  Anything further probably exceeds my troubleshooting ability, barring additional instructions.

Let me know what you think, and thanks again for your help.

Made it about 30 hours before it crashed.  Sigh.

Ok, I've setup a direct connection from the Comcast lead to the router.  Fingers crossed, but not optimistic.  This will be my last possible troubleshooting step before I have to have them out.

Uptime is 52 hours and counting, which is encouraging.  It's possible that the older cabling in this place is the problem.

So my question is, can Comcast set me up with an appropriate, modern cable to a central room?  My external hookup is very kludgy and definitely not a good permanent solution.

I'm renting this place if that matters.

Let me know, please.

@Bierp, just to make sure we are on the same page, are you asking if we can provide a modem for you and connect it to an outlet in a different location within the residence?

No, I have the Xfinity modem/router already.  It seems that the existing cabling between the Xfinity drop at the side of the house and the rooms inside the house is insufficient to prevent constant rebooting of that device.  In my testing, I've arranged to have my device connected directly to the drop, but that's really only viable as a temporary solution for the purposes of troubleshooting.  I need to relocate that device to a central room in the house, but I need adequate coax to make that happen without a repeat of this issue.

Generally, with a new service (I started this service in Jan), I'd expect Comcast to run the necessary cables to the target room.  Judging by the cable on the outside of this house, that's likely been done several times over the years, but clearly that old cable cannot provide adequate connectivity to the current generation of hardware, so I need to have something modern connected from the drop to a central room where I can place the router.

Does that make sense?

@Bierp Gotcha, thank you for clarifying :). Our technicians can replace outside wiring and in my experience, will be happy to cut a longer length of coax cable if you need to place equipment further away from your exterior walls. They are not permitted to do any type of wall fishing work, so they will not be able to install a new coax outlet on an interior wall of the home. If you require wall fishing, I'd recommend hiring a contractor.

Please send a direct message by clicking the chat icon in the upper right corner of the page, click on the pen and paper icon, then enter “Xfinity Support” in the “To” section. Please include your name and address and I can help you set up an appointment with a technician to replace your outside wiring.
