In a nutshell, improve what you can in your own wiring.
1. If you have extension wiring, remove it if it is unnecessary.
2. Replace internal extension cables with CAT5
3. Filter as close to the master socket as you can
4. Place the router nearer the master socket
5. Remove the ring wire from the extension cabling
6. Rearrange or shorten cabling
7. Disconnect your sky box from the telephone line
8. Replace your filters
9. Get a new router
Rationale
1. Unused extension wiring provides a length of cable through which noise can
enter the circuit.
2. Non-twisted-pair cable picks up far more noise than CAT5. For CAT5, read
CAT5e, CAT6, or similar solid-core cable
3. Less unfiltered wire means less noise
4. If you only need a phone line near the PC for broadband, consider replacing
the phone line with ethernet, and moving the router, = shorter cable, see 1,3
5. The phone line is a pair of wires, the ring wire is just one wire, and is not
needed if all analogue equipment is filtered (filters regenerate ring signals).
The signal pair should be two wires from the same pair in any twisted pair
arrangement (if they aren't, your speed suffers bigtime)
6. See 1,3. Consider RJ11 to BT431A leads to plug router direct into socket if
a telephone is not needed at that location. Avoid running cable next to
electrically noisy equipment.
7. Some models of sky boxes can be problematic, but the jury is still out.
8. Filters decay over time; cheap filters decay faster.
9. Similarly to filters, components in routers can decay, and power supply
components in particular; an old power supply may be introducing noise. You may
also find fitting RF chokes on power leads may help in a small way.

BT's stats are, atleast in my case, pessimistic, they suggest 2Mb, but I get 6
to 7. However, I have done 3,4,6,7,8,9 in the list above, and will shortly do 1.
