I decided to future-proof my set-up and get the Netgear CM2000. Just activated it here, and I can't seem to get locked into any of the OFDM Channels. The downstream keeps blinking, and according to the manual it means it is still scanning for downstream channels.
On my SB8200, I was at least getting 1 D3.1/OFDM channel, but getting the same miserable 19 of (24 or 32?) D3.0 channels:
