Are you getting the message 'Concentrator unreachable'?

FYI: Yesterday, 10//6/13 at about 2pm I replaced the plusnet TG582n router with my own new TP-LINK TL-WDR3600 dual band router to determine if the two plusnet routers I have used are the cause of the problem. I had an outage this morning 11/6/13 at about 00:30 but I believe that was because of PlusNet maintenance. The new router has been working OK but it's too early to say whether that has fixed the issue. If I get the problem again I will then swap to the modem the engineer left.

@GrahamClark
If at some point you go to swap the Modem, I'd do it when you can leave it off for an hour ( in the daytime as well), so the DLM doesn't see it as a dropped sync, because you have no engineer around to organise a reset if DLM makes a mess of things. Plusnet may have some difficulty persuading OR to do a reset as well, as it means someone going to the Cab IIRC.

Yes I noticed that as well on reading through the thread, and I think it could have some significance to what is going on.
I'd make sure that you put that section of log entries onto your Fault ticket and highlight those time differences. Whether this has any bearing on -
a) the cause of the drop in the first place or b) the session time-out - is anyone's guess.

Now I have my own TP-LINK router connected it'll be interesting to see what happens over the next days. One thing of note is that this router is issuing PPP info messages every two mins. I have no idea why and have asked TP-LINK why. These messages are
Jun 11 03:32:23 PPP INFO send_phase 2098 pppd_phase = 0xd
Jun 11 03:32:23 PPP INFO In pppd the httpd-id is 669, set link phase is 0xd
Jun 11 03:34:23 PPP INFO send_phase 2098 pppd_phase = 0xd
Jun 11 03:34:23 PPP INFO In pppd the httpd-id is 669, set link phase is 0xd
Jun 11 03:36:24 PPP INFO send_phase 2098 pppd_phase = 0xd
Jun 11 03:36:24 PPP INFO In pppd the httpd-id is 669, set link phase is 0xd
Look like some form of PPP keep alive to me but they could be anything. Anyone know?

As you mentioned it's stable for the last 8 days that the connection graph goes back but is happening every 10 days or so.
I'd suggest raising a fault at http://faults.plus.net and add the information regarding Concentrator unreachable, as you shouldn't be seeing downtime for a long period.
