Arris Router Restarts constantly (2024)

Is the connection dropping? Or is the modem rebooting? If the connection is dropping, then going off the readings you are giving, its your ISP. Keep in mind there can be internet outages with perfect upstream and downstream, all those readings are is your connection rate to the ISP.

If the modem is rebooting thats on your side. You can tell its rebooting because lights will be flashing when you lose internet. When it does it check to see if the unit is warm, overheating can make it do that. Something may have shifted in the house, or the heater from winter may be heating it up somehow. Make sure its not buried, lack of airflow may cause it to overheat even if the outside isnt warm. If you can rule out overheating then onto troubleshooting.

This doesnt happen often, but sometimes and ISP will update something on their end that will conflict with a modem running old firmware. If this is the case then when you log into your router there will be a notice at the top of the screen asking if you want to update the software, or firmware. Do so if there is one.

To me, with the hours you say its fine, an when it starts it either sounds like the heater is kicking on cause its cold outside and warming the router up....or your ISP is having a flood of users come on just getting off work. It could be your ISP has some equipment down that isnt allowing them to handle the load as well as normal, so if the first 2 things I said to check dont pan out call tech support and tell them whats happening. Most of the time if you ask for a lvl 2 tech you dont have to go through the annoying "unplug/replug" crap.

If your ISP says it isnt them, that its on your end chances are theyll want to replace your router, an problem solved. If you own it, an they wont take responsibility, then come back and there is other things to try.

Ok, this is going to sound like a stupid question....but when you get the power surges like that is your modem just recycling? (trying to connect) Or does the router reboot all together? Well hit on that part after you check.

First thing to check is your connections, Im sure you did but dont forget your connections outside the house. Weather can loosen connection at the box, or at the pole. If your in the US then ISP junctions (the box on your house) is your property, so you can go inside and check connections. There isnt anything in there you can tamper with anyways. Try to follow the line from your house to their pole, or wherever it comes from. See if the line is hanging lower than it should, or if its swaying (believe it or not that can cause problems). Look at the line to see if its cracked....this can be hard depending on where it is, an often times doing it at night with a flashlight helps because exposed lines will reflect.

Chances are, because of the times its dropping, that your ISP is overloaded. The stuff I told you to check with the lines is just standard, chances are theres nothing wrong but you never know. What the router is doing when it drops is key, if the router maintains its composure during the drop then its not you. If the router is rebooting then that could explain the readings your seeing as the router is forcing a reconnect and making sense of the data its seeing.

Every ISP is different, and there certainly are some crappy ones out there, but generally if you threaten to leave them and go to another then theyll hop right to you. If they dont help you when you threaten to leave its a very good sign that they are over-crowded.

I feel your pain, I was in the same boat a few years ago with ISPs.

Do you know anyone else with your ISP? Do they have the same issue? Since the router is rebooting and not recycling it could be an external factor effecting the router. If you do know someone who has your ISP an they arent having problems can you hijack their modem for a night to see if it does it?

Im still leaning towards ISP overload, specially after what you just said. But since the router is rebooting all together it could be a hardware issue.
