Even at that my speeds are only a little better than they were with ISP Channel. For the first month download and upload speeds were great then they fell off a cliff. That is ISP Channel speed. In response to SB TTR, those speeds look good. Stev32, that is the good thing about DSL, consistency.
Some cable companies seem to be faster but they are subject to loosing the speeds at peak times.
One thing I do like it the higher upload speeds. The only thing for sure is we all have Mediacom. Just keep posting and let us know how your getting along. I also have the Motorola 4100. In response to SB welp I've tried numerous RWIN and MTU suggestions that were given here, but to no avail.
