I posted on this subject back in February, recap:

Thanks for the many suggestions and comments, after trying many of these I
have been able to rule out most of the potential culprits - progress to
date:
€ I have had the same problem at three widely different locations:
- at home in Albany where maximum connection speed can 48000 but is
often less generally >33k but once yesterday was 9600
- at a house in Claremont with a PC accessing net with no
disconnections (connection speed here can be higher than in Albany but also
varies)
- at a bush location where max connection speed was generally 14k
at each location drop-outs are very variable - sometimes get long trouble
free connections at other times there can be drop-outs every few minutes.
Because the problem spans different locations (and a PC at one location is
not having the problems) I am assuming that the problems are not down to the
Telstra lines
€ I have tried using different cables from the computer to the wall socket
(including the one from the trouble-free PC) to no effect, so I have ruled
out a faulty cable.
€ I do not have call waiting activated and I have disconnected all other
phones/faxes - but the disconnections still occur.
€ I have tried letting the applications (outlook &/or explorer) initiate
the connection and also used Remote Access to connect prior to firing up the
applications - there did not seem to be any difference with either approach.
€ Sometimes the problem occurs during connection - remote access reports
connection at (speed varies) gets to 'starting PPP' and then hangs, finally
giving the error message: 'The remote side is not responding correctly.
Check the configuration of your control panels and try again'

The one suggestion that I haven't tried (because I don't know how) is to
limit the connection speed. I obviously don't fully understand this because
I thought the fact that remote access shows the computer connecting at
different speeds at different times meant that it could automatically detect
the appropriate speed to connect at. On re-reading some of the
comments/postings however I get the impression that once a connection speed
is automatically chosen, the computer tries to maintain this speed and if it
can't then disconnections will happen - if so then it may be worth trying to
limit the max connection speed to see if this is the case.

My question is how do I do this - the modem control panel allows me to
select a modem [ I haven't changed this - currently apple internal 56k
(v90)] but not that I can see to change the connection rate. I found a
folder with modem scripts in it but double clicking a script gives a message
that they can't be opened.

Also once I find a way to do this (and assuming it works) how do I pick a
speed that I can use at various places without slowing browsing to a crawl?

Any feedback from someone who has encountered and beaten this problem would
be greatly appreciated.

TIA
