The downstream levels could be slightly better, they are -5dB ideal 0dB, but nothing to worry about, SNR good. Upsteam transmit good at 44dB

By any chance are you using wireless? Wireless G is only capable of around 20Mbps, so that would explain it.

Try testing using wired. If you want better wireless speeds, try using a wireless N card.

still on QAM64, less bandwidth available on the network and probably causing high downstream utilisation

lazy rollout in your area, just flicking the config upgrade switch without adequate infrastructure in place.

Try and get tech support to realise QAM64 downstreams are wrong.
