Unfortunately, though, there are currently only three customer-owned modems approved for higher upload speeds: the CODA and CODA 56 from Hitron and the CM2050V from Netgear. The first two are from a company noone has heard of, and the last one is $350 (!) and includes pointless phone support. None of the near hundred other DOCSIS 3.1 modems on the market are supported, for no apparent reason.
