C7000v2 - modem keeps working but router keeps rebooting

Question

I am having a lot of problems with the wireless router component of my C7000v2. &nbsp;The WiFi connection is lost several times a day for a couple minutes at a time. &nbsp;The modem itself is fine; the wired connection to my telephone stays online while the wireless router is resetting and taking my WiFi clients off line. &nbsp;The ISP in Spectrum cable and it says the firmware is up to date.
&nbsp;
I’m wondering if there are any things I can try or any way to diagnose.

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.Any Wifi Neighbors near by? If so, how many?

The channel does not seem to matter.&nbsp; I have people around me using 3, 8 and 11, with 3 and 8 being the most powerful outside of my own router signals.&nbsp; (Using 3 and 8 is no bueno since they overlap with two distinct channels -- whether I use 1, 6 or 11 there will be some issues because of it.)&nbsp; Acrylic tells me that I have the only 5 GHz network in range, but it goes down with the 2.4 GHz connections.&nbsp; All wifi clients go offline together.
On occasion the wired connection goes out, too, suggesting a full, spontaneous reboot of the unit.&nbsp; But it doesn't usually happen; usually only the wifi goes out.&nbsp;&nbsp;I've heard some say that if there are too many clients a router can get confused (we have about 16).&nbsp; Not sure if that is worth pursuing.&nbsp;&nbsp;

I would contact NG support and ask about this. The C7000 maybe faulty.&nbsp;

Thanks.&nbsp; We've not easily been able to troubleshoot this one.&nbsp; I've tried tweaking some modem settings but that seems to make little difference in quality, since it is now disconnecting and resyncing several times a day.&nbsp; That got me to thinking about my cable connection itself.&nbsp; Here is what is being reported (see attachment) -- I don't see anything out of spec here though the downstream power seems slightly higher than ideal.&nbsp; Does anyone see a problem here?&nbsp;&nbsp;The logs are seemingly of no help.&nbsp; I don't see any potentially problematic entries around the time the connection is dropping.&nbsp; (I see a few DoS warnings, but not many, and I think that's not unusual and the firewall is enabled.)

IF the modem is now becoming a problem, might have the ISP check signal levels up to the modem. If things are good here. Try a different modem combo unit.&nbsp;
