Connectivity issues; Started Unicast Maintenance Ranging - No Response received - T3 time-out

About 35/37 days ago i started having issues with the internet. I could not get on Xbox Live for a multi player game so i ran a speed test and saw that the downlink speed was normal but the uplink speed had slowed to a crawl and i was now having 2%-8% packet loss each time i ran the test & the only other sign of any issue was the error log in my SB6183 modem which read: Connectivity issues; Started Unicast Maintenance Ranging - No Response received - T3 time-out.
Over the next week made multiple calls to Comcast customer support and as a result ended up replacing the modem, the router, ran brand new RG6 COAX inside as well as made brand new CAT6 jumpers. I literally changed 100% of my hardware, cables, & connectors.
However none of that made the slightest bit of difference. Over a week later I was at my wits end then 25 days ago i arrived home from work and saw a message on my pc stating that the service was out that mantinance was being done that affected me yadda yadda. When it was completed and i had service again everything was working 100% perfectly.
That lasted for 25 days then last night at 10:04 pm i got kicked off of xbox live. I ran a speed test and was disappointed to see that I am right back to square 1. I checked all of my equipment and everything is fine on my end but I'm having less than 1% of my normal uplink speed with packet loss and again the only other indication of anything is the log on my modem which states Connectivity issues; Started Unicast Maintenance Ranging - No Response received - T3 time-out.
One more thing to note it was extremely nasty and windy outside last night so I don't know if maybe some water got into something outside or what but Please help.

Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers as well as the error log entries in their entirety.

 

What is the exact make and model number of the modem ?

The downstream power is a bit high. Is there a drop amplifier on the coax line leading to the modem ? If so, try bypassing it and see.
