If you post your line stats people will be able to be more specific about what you might be able to get out of it.
If you have extension wiring in your house one of those BT iplate things might be worth a punt too, at £10 it is probably worth a shot.
In your Be user area you have some options too, the ones you are interested in are:
Optimise for speed = lower target SNR to 3dB (higher sync rate / less stable)
Gaming mode = fastpath on (i.e. no interleaving - lower pings / less stable possibly).
Also you could use something like DMT tool to tweak the SNR if your router supports this, I generally always found my Netgear DG834N syncs a good 2mbit higher than the Speedtouch too, so you could think about picking up an old DG834GT from the bay for a tenner and giving that a go.
cheers for your help, after making those changes in the members secction, it now syncs a couple meg higher
