Web traffic keeps failing intermittently.
Over the past few months our internet connection has been unstable. We contacted Xfinity, followed all troubleshooting steps, replaced the modem, and it worked until three months later when the problem returned. It worsened progressively until we experienced two consecutive days without internet. A service rep visited but the issue repeated shortly after. Another representative suggested a faulty Ethernet cable, so I powered off the Wi-Fi modem to see if the problem reappeared. That led us to get a third-party Netgear modem, which we installed and completed activation. Now the outage occurs every 20 minutes. I suspect the issue might be related to the router, so I checked its settings—each time it reports disconnection and the ISP’s DHCP isn’t working properly. My Asus AC3100 router is still functional, but I’m feeling frustrated and unsure what to do next.
You're a Xfinity customer. Have you verified your modem settings? Access them via 192.168.100.1. Review your connection here: https://www.dslreports.com/faq/16085. If your signals fall outside the recommended range or are near the limit, that’s likely why you’re losing service. Frequent non-repairable errors may also be the cause. When multiple modems fail, the problem probably lies with the signal itself. Also, if possible, try connecting the modem in a different location outside your home—if it works there, the issue is likely with your home wiring. To be clear, Xfinity usually won’t assist if the wiring is the problem, though running coax can be straightforward.
Thanks for the feedback. I initially changed the DNS servers to Google's, but after about half a day the issue persisted. After checking the modem and signal strength, everything seems to be within normal ranges. Right now I'm weighing whether the problem lies with the router or if I should try working with the coaxial cable instead, since I haven't done that before.
I'm experiencing the same problem right now... it seems the router is getting too hot and turning off.
