[FL] Internet speeds down the drain

So ive had mediacom for 2 weeks now the first week I was getting great speeds 30+. As of last week tho my speed has been horrible 0.80 - 10 range. Mediacom shows nothing wrong in the area but says my power ranges might be out of spec. I was also told my a tech that my docsis 3.0 modem could be the reason becuase its only taking in 1.1 speeds ???. I have a dedicated rg6Q cable from the outside of the house to my modem. Here are specs and stats from modem. please let me know if anything looks out of wack

I wish my upstream was in the 30's...

I am having some major issues here for the last week, though they claim the signals have only been bad for a few days. My downstream is -11dBmV and my upstream is 58.2dBmV and so i wait for my fourth or is it fifth tech visit.. Ugh...

Anyway, as for yours, the Upstream looks great. The Downstream the receive levels are VERY hot... 0dBmV is the best, too high or too low and your going to be having problems. The max is a range of -15 to +15 on most of the modems i have looked at the specs for, most websites seem to claim you should be between -12 to +12, your signals are a bit high, too much is not a good thing.

You said its a dedicated cable from the outside of the house, do you have a splitter out there to send another cable off to the tv's or do you just have internet service? If you don't have any splitters inline i would put one in just to get that 3.5dB drop from the splitter. Your modem is a transceiver, the receive level can be so high as to overdrive the modems receive. I wish i had your problem!

thanks for the help I got my downstream down to 5.8, 5.6,5.2 but my upstream jumped to 43.2 is that still within a good limit? hope you can get your problem figured out, i guess its a good thig i was on the high side easy fix.

Anything in the 30's and 40's is fine, my upstream was 43.7dBmV for almost six years, then suddenly bam it went through the roof.

I know they still have a connection to fix somewhere.
