ARRIS WBM-760A finally shows all-green in southern Prince George's County, MD (yes - Accokeek, MD - 20607). I already had four-channel downstream - I now have three-channel upstream (two-channel D2 ATDMA and one DOCSIS 1.x TDMA - likely CMTS issues) as well. Given that I have Performance (not Blast or Ultra) I refuse to quibble.
