Speedtouch sounds dirty. Anyway, I should be getting 24Meg and I'm only getting 11, which seems a bit shit.
I have the latest firmware, a decent Cat6 patch cable and plugged into the BT master. Be* profile is "standard" and "gaming mode on" (whatever the fuck that does). I'm about .... far from the exchange. Line attenuation is pretty average but I seem to be getting a fuck load of CRC errors (what are those?).
Anyone got any idea how I can improve things short of getting a new router?

That's what I get. I have mine optimised for speed with gaming mode on. Optimising for speed decreases the amount of frequencies that are ignored by the router, it'll increase speed but may reduce reliability. Gaming mode turns off various error correction stuff at Be's end which also increases speed but may reduce reliability.
My connection is 100% reliable with those settings but then my line attenuation is lower. CRC and HEC errors generally don't affect anything, I get loads as you can see. As Pete says, use decent quality cables and filters. You can also try removing the ring wire from the master socket which can reduce interference: http://www.kitz.co.uk/adsl/socket.htm
Well this is fun. Any ISP (including BT ironically) you contact about broadband speed degradation will suggest you plug into the Test socket on the BT master socket to eliminate any internal wiring issues from the equation. So far so normal. However, new houses like mine no longer have a test socket - BT Openreach in their infinite wisdom instead put an external XNTE test socket outside the house with a proprietry socket that the user has no way of plugging into (without getting funky with wiring and shit). Of course BT Openreach responsibility stops at the XNTE so any testing you ask them to do will cost you. Go figure.
Unfortunately this breaks the ISP support monkey-see-monkey-do flow chart and they go into an infinite feedback loop and explode.
So I'm back to square one: my ISP's support process doesn't accomodate the new BT Openreach XNTE test socket, so they can't tick the "Internal wiring" check box and won't progress the ticket to "give me a new fucking modem cos mine is borked".
