The last two mornings I've woken up to find my network not working. I use a router, a gentoo box for file/mail/web/DHCP etc server, and several windows boxes. Resetting the router has restored things, but I've seen huge numbers of these messages in my log:

When I restart the router I get the expected response: | Quote: |

I have the DHCP server function disabled on my router.
Can somebody explain what's happening? |

I also once had such messages until I found my network switch was defect.

| I'd more or less come to the same conclusion. I changed some of the settings on my Linksys router/switch (access control) and that fixed it. Looks like the firmware is suspect . . . A lot of these gadgets seem to have problems. |
