I getting tired of this message and I am so close to switching to Fiber internet.

when i first moved to my new place, the internet was perfectly fine for about 1 year and then more drops during internet usage. My upload power dropped from 38dBmV to 26dBmV. So I did some research like anyone would and bought a 8Db attenuator Pad on amazon and it seemed to help a bit but I'm still having issues with xbox online gameplay. As much as xfinity promotes gaming online, from my experience I think its terrible. Most of my friends that I play with all have fiber optic internet and they seems to be enjoying their xbox, as for my xbox its just a paper weight doing nothing. 

I have good download and upload speeds, and never really drop connection. The only problem I have is playing my Xbox online with friends. During online gameplay my upload speeds are terrible 1-5mbs. I have updated my firmware on my modem ran speed tests and a ping test and my power levels are in range after the fact I installed the 8Db Pad. As a customer should never go through this, especially since we are paying customers. For example your cell phone provider starts dropping more and more calls, you're going to switch to a new provider, right? Well that's how I am feeling right now.

I don't know what is causing this error that I'm getting "Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;

I have googled it and I see other people with the same issues and heard of stories where xfinity tech don't really solve anything, so xfinity customers are stuck with this issue for months on end. Does anyone have any recommendations for this issue? Thanks in advance!!
