I have looked through all the logs I can find, and as far as I see, it was happily renewing IP addresses via DHCP and logging firewall events up to about 04:34 but can see nothing beyond that. When I discovered the fault, I found that my iPod would not go online, and my laptop (which was on) had lost contact with the default gateway (the plug) so it seems the newtork services had hung or something, although all leds seemed to be blinking away as normal. I did first reset my router - daft I know because by then I had realised that I could not ping the local address. Then i had no choice but to reboot the plug by pulling the power cord. It came right back up and seems to be ticking along fine.
Can anyone give me some troubleshooting tips to see what happened, as I say the logs aren't that enlightening - as an example a snip of the syslog:
