Is it my line or my Router?

Hi
On ADSL Max and connection around 7500-8000bps. However, monitoring the
router it initially connects with a 6dB noise margin but then quickly
(5-10sec) drops to 1 or 2 and then connection drops sometime in next 15
mins. It only happens in evenings; Sat & Sunday it holds on all day.
BT have said there is nothing wrong with line and will not adjust BRAS
profile to make it connect at a lower rate. They just say every time it
drops I should reboot modem.

What I don't understand is when the connection comes back up it usually
results in an increase of downstream rate. It does something like
7900,8000,8064,7900 etc. I would have thought it would keep going down if
connection is continually dropped?

Modem/Router is Zyxel 660HW-61 with latest firmware , though previous
versions are the same.

So is it a line or router problem I should hassle/investigate further?

thanks

Paul

can go either way, if interference takes out some frequencies it may
use others to the same or better effect.

If it flaps enough it'll get a higher SNR margin target.
