I thought you said earlier that you normally plugged the router in via an 
extension (ie the "home wiring"). When you say "that's the only way it will 
work at all" do you mean during tests today, or that this is how you normally 
have it plugged in?

Kitz reckons that the Netgear DG834 is one that can keep the connection well, 
even with interference problems.

This sounds like a classic case of interference. It could be almost anything - 
from the Ionosphere (remember getting AM transmissions from europe in the 
evenings?), water in joints in the BT line, or other people turning on their 
modems.

At least your WiFi part seems to be working fine.

A little, but you are probably going to get numbers on this, so we can see the 
actual state of the line as far as the router/modem sees it.

Probably the best thing you could do is to leave the modem/router plugged into 
the test socket at the back of the master, and run a program to monitor the 
line statistics. If you have the right kind of modem, you might find 
"RouterStats" useful:

The graphs might give you an idea of whether you are suffering from occasional 
bursts of interference, or whether it is a constant problem.

Almost certainly no improvement in reliability. At least not if the phone 
connection stays with BT, as the problem is probably to do with the line to 
your house.

You might find another ISP more responsive to your plight than AOL, but I have 
no experience of whether they are good or bad. I've found that you can get a 
decent response from PlusNet provided you go via the forum rather than the 
normal support desk, and even then it can take some perseverance. Especially if 
BT need to be called out.

Being remote shouldn't affect your share of the bandwidth from the exchange to 
the rest of the world. 

Your main limitation will probably be that the length of your line leaves your 
modem syncing to the exchange at a relatively low speed level. Your current 
problem is *probably* that interference causes the sync to keep dropping, and 
forcing the mode to resync with the exchange. When the sync goes, your browsing 
experience will tend to show as pages that fail to load, or downloads that are 
extremely slow.

There are a few things that BT and your ISP can do to the line to try to make 
it more reliable, such as turning on interleaving, or increasing the noise 
margin. Both will tend to make your connection slower - but the exchange has 
probably already tried these out for you.
