Router keeps restarting repeatedly.
Router keeps restarting repeatedly.
I purchased this router from Best Buy. https://www.bestbuy.com/site/netgear-nig...Id=4403100 When it functions properly, it's excellent, but occasionally it restarts unexpectedly. The internet goes down for a few minutes before returning to normal. Xfinity reported no problems with it. I've reset it to factory settings without success. There seems to be no regular timing—like it might restart at random times, possibly every few hours or even longer. Any suggestions?
Review the router/modem logs via the advanced settings menu. They are located under Administration > Logs. Are you noticing any unusual heat?
Are the timing consistent with the router's restart? I experienced a similar issue but used a different router and modem. The main concern was a damaged coax cable from my home to the street aggregation unit. Verify that the coax connection at the router's rear end is fully secured. Ensure all connections from the modem to the ISP entry point are secure. If any coax splitters exist along the path between the ISP entry and the modem, remove them temporarily to test.
I’ve also had someone from the neighborhood inspect the cables and they seemed fine. We even removed a splitter that was stored in our closet before. It appears things have deteriorated more since the pandemic started, though I’m not sure why.
The cables have not been inspected visually. The ISP technician should use a tester to check for noise on the line. In my situation, the damaged cable was in the street aggregation box, making it impossible to see the damage. If the line is faulty, it might be recent. To determine if the issue lies with your modem, you can purchase a used or new one, test it, and return it afterward.
The Xfinity Tech checked the signal and made some adjustments. It's unclear if it was tested for noise specifically. He tested throughout the process—from the device to the house, then outside to inside. I also purchased a new router from Best Buy today to verify and see how it performs. I'm just curious about this in general or for potential future problems.
I'm not completely clear on how modem/router combo units function. It seems uncertain whether one can restart separately from the other, or if they both need to restart together. The issue appears to be related to the modem side, so if only the modem restarts, your Wi-Fi network will remain available but you won't have internet access during that process.
