Based on your info and the fact that I see no problems in the pingplotter results, there must be some type of Mediacom channel bonding problem in your area.]]> http://www.dslreports.com/forum/Re-MN-Slow-Downstream-Upstream-Ok-27964781 Thu, 31 Jan 2013 10:17:47 EDT Re: [MN] Slow Downstream, Upstream Ok? http://www.dslreports.com/forum/Re-MN-Slow-Downstream-Upstream-Ok-27963856 IP: 64.30.224.58

All started out with bad signal levels, yesterday they replaced my drop, they got the signal levels where they should be and the connection hasn't dropped.

Motorola SB6180 DOCSIS 3.0

Downstream Value
Frequency 111000000 Hz
Signal To Noise Ratio 38.9 dB
Power Level 2.9 dBmV

Upstream Value
Channel ID 2
Frequency 32000000 Hz
Power 40.7 dBmV

I have two of this model modem, i have swapped them, no change. Also other customers in this community, eight of which i have seen in person, are also getting slow speeds. The DOCSIS 2.0 modem owners are getting around .3-.5mbps downstream, the DOCSIS 3.0 users are getting around 2-3mbps thanks to channel bonding.

I even went so far as to go to a friends house and swap their RCA DCM425 with my spare SB6180, their speed jumped from .3-.5mbps up to around 2mbps. I then swapped back to their modem and their speed dropped back down to .3-.5mbps. So its easily replicated.

Here is some of my latest speed tests.

[att=1]

[att=2]

The Upstream seems to be ok, its supposed to be 2.5mbps up, and i generally meet that number or even better no problem. The downstream on the other hand sucks. I am paying for 30mbps and i'm getting a tenth of what i should have. If i was at least averaging 20mbps i would be satisfied, but at these speeds the local DSL provider is faster, and thats saying something!!!
