You may need a new router.  What router do you have currently?

Very very unlikely a phone extension will be on CAT5 cable, it's usually
just the cheap telephone extension cable stuff which isn't suitable for
networking (well not Ethernet anyway).  Saying that, it might be possible
to replace this cable with some CAT5 cable and have the modem downstairs
and the router upstairs, you may be able to persuade the BT engineer to do
this for you as part of the install maybe.

IIRC the modem is wall mountable and it's not that big.

Ahh yeah just mentioned about that above. :-)

Ahh it's not that complicated really.  What is complicated is getting
cables to where you want them for a nice fast stable connection while also
taking into consideration the Wife Acceptance Factor (WAF).  My ex-wife
wasn't so convinced about me replacing a coax TV connection with CAT5
cable.  Luckily when we split up I got the CAT5 cable back (which is now
running through a hole outside the house cable tied to the drain pipe and
back in to the upstairs bedroom where the other cable TV connection comes
in :-) (oh and I don't currently have a significant other to please, just a
couple of daughters who would be more upset if we didn't have internet).
