I understand that T3 time-out errors are common and typically can go unnoticed unless they appear often. I have seen anywhere between 10-15 T3 time-out events per day over the past few weeks, and while power-cycling our modem does fix these issues for the time being, we still lose connection 3-4 times a day because of this. I have chatted with many agents and done every troubleshooting step they have asked (and some that I have read on the forums/online) to try and solve these issues, but am always met with "your modem seems to have a few errors, would you like me to send a refresh signal?"
Today, 6/25/2020 I have tried to contact Comcast through phone calls (it wont allow me to move past the refresh signal, the callback feature is not working - it says 'There is an issue connecting you to an agent right now'. I have tried DM'ing them on twitter and have not received a response after ~30 minutes, so now I'm trying here. I'm supposed to have a technician scheduled to come out via a chat with an xfinity agent yesterday, but there are 0 scheduled appointments for me.
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 ?
I believe that's supposed to be under the diagnostics tab once I've signed into my modem, but I don't see the stats for any of the things you mentioned. I've gone through each of the different tabs and couldn't find anything
Hmmmm..... Well if you can't find them a Comcast phone rep can give them to you . 1800comcast.
