To use a telephone call analogy, in the first instance it looks like the line went dead. In the second instance does "terminated by peer" mean that Plusnet did the broadband equivalent of putting the phone down on you?

ReedRichards is on the money above^
They're both nothing really to worry about, the first was probably caused by routine BT maintenance tbh (seen as its between 00:00 and 03:00) -- although the connection came back very quickly (could of been just a random blip though)
the second was probably either the same as above - or:
a) pn maintenance
b) DLM changing your profile/line settings
c)pn changing your ip/traffic management profile
d) completely random one-off event
I certainly wouldnt be too concerned, around 1 month uptime is absolutely fantastic tbh.

I've checked our connection logs for your line and the amount and frequency of disconnections are nothing to worry at the moment. See below:
Certainly monitor this however and let us know if they continue/get worse.

Thanks for the replies, 25 days is a record my previous best IIRC is around 8 days.
The only moan I have about the 7800N is the log only appears to hold around 4 days entries, records a --mark-- every hour and theres no way to have it send a email if there is a disconnect, unless anyone knows otherwise?
Thanks
Steve

This means that you can get it to send those "logs" to another machine (provided the receiving machine is on of course!) which will add the lines to a database (dependant on what software you use)
This means you can scroll through the logs, and see "what happened" even if the router reboots unexpectedly!

Can anyone recommend software to use with the syslog function that Matt_2k34 mentions?
I was hoping for something similar to my old Netgear DG834N which could be setup to email the logs hourly/daily or if the 7800N had a option to choose what entries are made to the log would have been ideal.
By the way I'm running 1.06b firmware, didn't see any real need to update - if it ain't broke don't fix it.

You need a syslog server, just google it and you'll see various ones available for free depending on which OS you use.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
