CHAP authentication failed - wotsit telling us?

A friend of mine has lost his broadband connection. He has recently been
upgraded from 0.5Mbps to 2Mbps on demon ADSL. Perhaps these 2 things are
related?
I don't know which particular tariff he is on. He does have a static IP
address.
He has a Netgear DG824W router - yes 824 whatever that is (or was). In
order to try to eliminate possible problem with his router I substituted my
DG834 and tried connecting through it.

It was from the DG834 that I got the "CHAP authentication failed" message.
I assume this indicates we have an error in the name/password combination
for logging on to demon. Is this correct? (If it is it must have been
changed - we have quadruple checked our settings.)

Demon technical support wanted to keep me waiting on the phone for 20
minutes - apparently quite normal practice with them, hence this posting
which could save us time.

You might want to try connecting briefly with user "(E-Mail Removed)"
and then putting the old details back in. I've been told before that
sometimes something somewhere (vague I know, but it was DSL tech speak) goes
"stale" and the above procedure somehow fixes it.

Yes that would certainly seem to point to the username and password.

(Assuming everything else is working that is, a big assumption <g> )

I tried using this username and a blank password on my own (working) router
but it failed with an invalid IP address? Is that the correct name above?

Cut & pasted from a working script, so it should be correct.
What was the IP address?
Did you get back online after putting back the correct username/password?

I would persist with the ISP. I recently had problem which eventually
was because CHAP authentication failed. I had (a few days earlier)
asked the ISP to confirm everything was in order at their end and was
told "All OK problem at your end".

After days of trying all sorts of solutions I (thinking it was the
equipment or existing Network settings) I went through the log for the
modem and saw the CHAP message. Contacting the ISP again with this
more definite indication of password/username conflict I got an
immediate response confirming the error was with them. They didn't
tell me what the error was but from then everything was OK.

What am I doing wrong? I entered bt_test<at-sign>startup_domain as the
login name with a blank password and still get "Invalid IP address" -
nothing further to help. I leave the ADSL settings as they are for my ISP -
I am with zen and on 0.5Mbps supply.

so you are using a known working router from another line, it has ADSL
sync and the bt_test login doesn't work on a line setup for Demon ADSL
??
