I've put cr9 back in, and changed only one thing. I did have a private range ip address set on the wan interface for connection with the modem (used to work flawlessly with cr8), I have removed that one now. Although there's no logging in the syslog about renewalls I still am online past the 4 hour mark now. So renewals take place, but do not get logged anymore I guess.
I think this could be the problem. Being the fact I hardly use the modem configuration website I have left it like this for now.
Hmmz, spoke too soon, just got disconnected. Unfortunately nothing is in the log that's out of the ordinary. I'll go back to cr8 now, can I mail the logging to you Oleg?
cheers,
Wiz
