Hi
I thought the logs were non-volatile and remained after a reboot.
I'm on 80 days sync so far with mine, it's constantly getting polled on Telnet to get stats, but it is in modem only mode and I rarely log into the Web UI. Will be interesting to see if it survives the next few weeks as I get 100 plus days up time.
The firmware has never been 100% reliable, and it will be some type of memory leak triggered in certain circumstances, and they probably couldn't track it down without more effort than they are willing to put into it.
Regards
Phil
