Non-Stop RCS Partial Service/Lost MDD Timeout Errors

I'm getting to the end of my rope with the tech service support I have so far received. I have intermittent service drops and modem resets. After being told the issue was my previous Arris SB6141, I went out and bought a new Arris SB6190. Still having the same issues. So I called back to then try and schedule a service tech. After a couple of hours of holding, explaining, re-explaining, and being patient I finally had a service ticket open. So this morning the tech showed up and he replaced some connectors, reinstalled a ground wire, and replaced the jack in the wall. After that my internet was even slower! I was getting 3mb down and .5mb up. He then told me that another ticket was created and said I might hear something in a week. So after a couple more hard resets, I was able to get my internet speeds back to normal. But this evening, another modem reset. This is unacceptable, I am a fulltime student and desperately need the internet to perform all of my online classes.

What is the most frustrating is, I do know enough to look into the error logs for both my modem and my router. Looking through these specifically on the modem, I can see that every 15 seconds I am receiving RCS Partial Service/Lost MDD Timeout errors. So I obviously brought this up to everyone I have spoken to and it has blatantly ignored.  Prior to today, I was also regularly receiving TLV-11, T3 Timeout, and T4 Timeout errors as well.

Re: Non-Stop RCS Partial Service/Lost MDD Timeout Errors

The downstream power is too low / out of spec. Please also post the upstream power level numbers.
