The Motorola bsr's only have three downstream channels where the Cisco ubr's have 4.

Your power levels are in range, but your snr's are borderline

Universal Broadband Router by Cisco use 3 downstreams.

Broadband Service Router by Motorola use 4 downstreams.

Just 2 different makes of Cable Modem Termination Systems.

No doubt explains why my upload is crap and download fluctuates by the minute.

The plooperhub has a problem with Motorola BSR's which VM admit.
