Until couple of years ago, our wiring had a drop cable going to a GPO
lozenge box from which two round white cables went, one to a socket
downstairs and one to a socket upstairs. The sockets were marked British
Telecom, with the original dots-and-dashes logo immediately
post-privatisation. That dates the sockets to the early 80s, though the
wiring may have been done before that, feeding hard-wired GPO telephones
originally.
We had good ADSL to the upstairs socket from which I fed a fairly crappy
ribbon cable extension lead to the bedroom where the router lives. It
gradually increased over the years to about 7.5 Mbps.
Then very suddenly ADSL became atrocious: the router would lose sync for
hours at a time and when it did synchronise it was at a wide variety of
rates. Things were always worse after heavy rain, which suggests water in a
joint somewhere.
BT OR (requested by my ISP, Plusnet) attended twice. The first time they
replaced the upstairs socket by a modern non-faceplate socket, correcting a
wiring fault at the same time. The second time they replaced the BT lozenge
with a faceplate master socket and connected the existing two cable runs to
the faceplate in such a way that they were isolated from each other and
didn't constitute "star wiring" which apparently is the cause of many ADSL
problems.
Even at the master test socket, with the house wiring disconnected, ADSL was
still poor compared with what it had been until a few months before. We were
going to get BT out again, but we decided to treat ourselves to "fibre". The
reduced cable length to our cabinet and maybe the switch to VDSL which may
or may be more resilient to bad joints seem to have eliminated the fault.
At the master socket, with the house wiring unplugged, we got about 30 Mbps.
With it connected and the router still in the master socket, it dropped to
about 25. But it was a hassle having to use Homeplug to get Ethernet from
beside the front door up to my study, so I tried the router in its original
location, using all the dubious ribbon cable. That reduced the sync speed to
about 20 which I decided was tolerable (especially given the bigger benefit
of increased upload speed from 0.5 to 7 Mbps) given that the router was
where I really needed it to be so it was a) next to the computers that
needed 100% reliable connection (I don't trust wifi to work 24x7 without
needing occasional manual intervention and reboots of router or PCs), and b)
higher up, giving wider wifi coverage for laptops and mobile phones.
The moral of this is that sometimes BT OR don't fully investigate faults
that may be outside the house, instead concentrating on wiring "faults"
(usually obsolete wiring standards), and that sometimes it is better to
suffer a slight reduction from the very best that you can get if it gives
you a router where you really need it.
It also highlighted that BT OR engineers are not always up-to-date with
policies. Until literally a week before I first called BT OR (via my ISP),
BT OR would relocate a master socket to where you needed it (within x metres
of the original location, to avoid people taking the piss) and both BT OR
engineers urged me to request my ISP to commission BT OR to do this, which
was my right to do. But they were out of date in their recommendation. I was
just too late, so I'd have had to pay them £150 for them to install a data
socket (filtered) where I wanted it, so I chose to use the amateur method of
achieving this, given that the penalty was not a *dramatic* reduction in
speed.
