Constant Random Disconnects- T3 error

I have spoken with a rep already who stated that Xfinity would only send a tech out if I paid for it, which is ludicrous. I have checked my modem stats and every time i lose connection i get a T3 time-out error. I lose connection on all devices both wired and wireless. I work from home and can not keep having these interruptions. I have had a tech out 3 separate times for different issues and we always start with the power cycling, checking coax cables, etc. Every single time i have provided xfinity with my modem logs because it has never once been my equipment causing the issues (I am not tech illiterate. I troubleshoot my equipment before i call with issues). I have tested with different modems and routers on more than one occasion with the same results. I have no splitters in my line, my cables are fine, and my equipment is made to handle more bandwidth than I pay for. Arris S33 modem and Nighthawk RAX30.

Secondly, My plan is supposed to be 1.2gbps down and 200mbps up and I am only receiving at most 950 mbps down and less than 10 mbps up. Again, all equipment can handle the speeds i pay for and I have speed tested on MULTIPLE devices. My PC is wired in, my husbands PC is wired in, and i have tried with a phone and my work laptop which are both on the WiFi.

The below is the error i receive every single time i disconnect (with MAC redacted):

Started Unicast Maintenance Ranging - No Response received - T3 time-out

The below is the status on my modem:
