My internet service has been going down at least 10 times per day. I observed the problem started around the same time my speeds were increased from 75 to 100Mbps on 12/23/2017. My modem shows these service interruptions as T3 timeouts - when the modem does not receive a response within a specified time from the CMTS to a RNG-REQ message, it reboots itself. I have contacted Xfinity support twice but their Tier-1 staff is limited in the services they can perform. The first time they performed a "health check" and of course everything looked fine from their end. The second time they suggested dispatching a tech but I am not convinced the problem is related to my home equipment. If anyone reading this can provide expertise - PLEASE help. Thanks.
Solved! Go to Solution.
What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?
Hope things hold up for you. Good luck !
