There are several reasons that this may be happening only a small subset
will be down to line quality or internal wiring. Are you sure that it is
synchronisation with the dslam that is being lost? If that is so is that
a known issue with the routers that you are using?

I'm having a running battle with BT at the moment with the home phone
where they claim all is ok but the ADSL is down more than up and even
the phone is unusable most of the time!

The links I have found useful so far are as follows.

* Has rudimentary testing.

Can you move the Router and microfilter to plug directly into the BT
master socked and disconnect every other extension? If the problems
persist they are not related to your clients home wiring.
