No Ranging Response received - T3 time-out

I had a tech out a few months ago after upgrading my Internet speeds and not being able to obtain promised upload speeds. He voluntarily replaced one of the outside lines and coax splitters. Then, suddenly there were frequent announcements that work was being done in town that lasted over an week, no explanation given.

Unfortunately, family emergencies kept me at a hospital. Back at home I still wasn’t receiving advertised upload speeds. Things have finally calmed down and I went to take a closer look at what was going on because we have been receiving intermittent disconnects.

Two days ago, I went crazy speaking with online outsourced tech support and got nowhere. I even posted some of my modem’s logs for them to see the disconnects and errors. When one rep found out I had been using my own modem, he simply stated I needed to rent one from you which is ridiculous. I’ve had my own modems for over 15 years without any issues like this. In fact, the modem was working fine prior to the speed upgrade and also the original person updating my modem’s bootfile.

I can’t afford to have these intermittent connections, so I replaced my 1 year-old supported Motorola Docsis 3.1 modem with a newer Arris S34 last night and provisioned it. 

Lo and behold, I’ve gone up from ~45 mbps upload speeds to around 340 mbps speeds. 

It would have nice if your techs were knowledgeable/trained enough from the start to let me know that the poor upload speeds could have been resolved with a newer modem that had more upload channels. It would have saved everyone a lot of time.

This aside, I’m still getting some critical errors that I’m monitoring closely. I’ve checked my connections and the coax is a home run. The connections are all tight, even the new ones on the outside. No splitters. T3 critical errors indicate that the problem is a CMTS communication issue back Xfinity, with the intermittent problem likely at the street. I don’t know if you have a newer bootfile for this brand new model (also recently released) that could address these errors.

It’s a new modem, and I was having issues with the previous one as well so I’m ruling out these supported modems as a culprit. I don’t want to be held random to your modems as a “solution” either.

Please address this without giving me the run around over and over again. Thank you.
