Slow Internet - Modem Event Log Shows Critial Errors
Hello, we have noticed a steep drop off in our internet speeds which began a couple weeks ago. Additionally, on at least 2 occasions, the modem appeared to restart (or crash?) on its own and took about 30 min to get back online.
I have a Netgear CM 500 modem that I have paired with a TP-Link Archer C50 router. Internet is provided by Xfinity (Comcast). We’re signed up for “speeds up to 100 Mbps,” however recent speed tests show our download speeds in the low teens and single digits, and upload speeds in the low single digits. I had an Xfinity tech come out to check the cable connections, and he said everything looked good on their end, and that the modem was likely to blame. After he left, I found the modem event log (see screenshot) and it’s showing almost constant “Critical” errors. Is there something I can do to resolve these errors? Would the issue be with Xfinity or the modem? Both modem and router are about 15 months old, had Xfinity the whole time with no real issues until about 2 weeks ago. Coax cable goes right from the wall to the modem, I’ve tightened everything I can and the modem/router have been restarted many times over the past couple weeks.
