Can any of the Draytek models be configured to support sppeds up to 300 bps? If so, which one? If not, when will Draytek relase such a model?

I have a 2820n and an AP 700 - and caanot see any relvant settings, and my clients all seem to connect at the one speed using one channel.

I have the same setup to you (the ap700 is wired to the 2820 used to be WDS but found that very unreliable) and i am getting up to 300 from either. My sttings are:-
Mode - g and n
2820 channel - 6
Ap700 channel - 12 (some macs cant see 13!)
Home plug wireless n extender channel - 1
(its important to separate the channels as far appart as possible, as n uses more than one channel, to get the best performance but also to take account of neighbours use of the channels)
Security must be - WPA2/PSK
operation mode - greenfield
channel bandwidth - 20/40
