Sorry Bob, not sure what you mean?

AFAIK my PPP sessions don't "expire", they just get disconnected... and all I can get from the router is the time of disconnection (but not the cause) and the time when authorisation is successful and I'm back in business (usually takes about 70 seconds or so).

does the PPP session uptime tend to match the DSL uptime or can you not see the latter as its on the Openreach modem ? I think I would be buying my own VDSL router to learn about it, when FTTC comes here in 2020

In reply to a post by yarwell:

There are three LEDs on the modem, one of which is for power. If I can't get the information from them, I can't get it at all


eta- if I happen to be at or near the computer when the link goes down I can see the DSL LED flashing as it retrains, of these occasions (maybe 70% of the times it drops) I think only once have lost it without a retrain, ie just a PPP drop.

Ah right . Sorry about that.

I was thinking of it in ADSL router terms, where you can see the PPP session start time and expected expiry time. So knowing those you would know what the lease length was and if the next session start time was earlier than expiry due time it is some at the moment unknown trigger.

On O2 with Netgear routers there used to be a problem where the lease did not renew when it should. the result was that the PPP session dropped and that was the end of things, although there was still sync with the exchange.

With what yarwell came up with, about the new profile update method and the 20-second trigger on the PPP ... and so on and so on. Just looking for seemingly unrelated events that might add up to something.

Wouldn't that lease time refer to a dynamic IP address? I'm on a static IP.

Admittedly that doesn't stop it having a lease period, but I've never seen any evidence of it- these things usually show as a brief spike of lost packets on the BQM and I've had weeks go by on occasion with nary a spike.

it wasn't a lease time it was a PPP timeout - making sure it was short enough to catch a resync and renegotiate, rather than keeping the PPP session up.

Ah, OK, thanks... I can't now be certain, but I don't recall any of the ADSL routers I've had giving that information anyway
