Only 4 downstream channels with sb6183.

Upgraded from the 6141 today to the 6183 and am only getting 4 downstream channels and slower speeds than before.

I chatted with a support rep online and talked to two reps on the phone that weren't able to help but I see that some of the mods here have been able to fix the issue.

Before you ask, you can reset my modem at any time. ;)

Thanks in advance for the help.
