Hi tactilis,
as I started reading your thread, my thoughts turned to "internal wiring" and I see ejs also picked upon this possibility (mention of the bellwire in the context of BT speed estimates - quite correctly).
Well done for the pdf comparison, that immediately led me to a couple more thoughts, so a few questions to follow and checks for you to do.
But first, just a quick mention of Routerstats, I would start with
Routerstats Lite as it's Plug and Play without complex setup problems and only go to the full RouterStats if the situation merits it. (Download the zipped versions and install in your root directory - not Program Files)
Ok, Quiet Line Test already mentioned - keep an ear on it. It's also probable that your line is speed banded - likely due to drops/reboots and errors, but whether the line reset actually occurred and removed any banding will need CRT to check.
Whether or not it has, resolving an further issues/causes of the low speed would be best before any further reset action on the line is taken. ejs rightly mentioned the FTR. I've seen cases where lines have been fully reset under "faulty" conditions resulting in a lower FTR and hence defeating the whole object of the FTR in the first place.
OK, questions and checks.
Do you have a
Master Socket like the one on the left?
Do you have any extension phone sockets, and where are you currently plugged in?
Do all your
Microfilters look like this?
Are you using any extension leads either between a socket and filter, or between a filter and the Modem/Router?
If you have extension sockets, can you have a look at the wiring behind one of them (not the master or the one you have the Modem/Router connected to at this time) and tell us the colour of the wires and terminal numbers they are connected to?
In future, if you wish do do anything involving loss of sync (even a reboot situation), use the following Disconnect method -
Log in to the Modem/Router, in the Internet box, click Disconnect to drop the PPP Internet session (this is not the sync), wait about a minute and then power down the Modem/Router. After about another minute you can unplug it from the line.
Do whatever is needed, but stay offline for at least 10 minutes. When you re-connect and power up, Login to the Modem/Router and click Connect to establish a new PPP session.
Don't do this more than 5 times in an hour, then leave it for the rest of the day. This method is to help stop the Exchange DLM from thinking your sync loss was a dropped connection.
(Anyone with a modem/router that doesn't have an interface for you to drop the PPP session, should just pull the power plug and wait a minute or two before unplugging from the line).
One further point, especially applicable to long lines, you will get very small differences in sync speed every time you sync, so just because you get a
marginally better sync speed in one situation, it doesn't
necessarily mean that situation is better than another situation.
PS. You can do a Disconnect & Connect (without a power down) to Gateway hop.
HTH, I'll keep an eye open for your answers.
Edit: Do you have a (any) spare filters?
