7800N DHCP server not serving

Post by PDilly » Sat Oct 31, 2015 2:15 pm

For the first time ever my 7800N lost the plot during the night.
I found that my NAS drive had booted up with an IP address putting it on a non-existent subnet
There were no entries on the DHCP table.
Rebooting the router and restarting the NAS drive put things right and populated the table.

Is this a sign of failing router?

Regards
Pete

Have been on 1.06h dt2 for some months.

Prior to that, although DHCP table wasn't populating, I've never ever had any device show up with same subnet address and IP address before.
It should have been 192.168.1.108 & 255.255.255.0 (still within lease) but both address and subnet were 192.168.1.168

It was LAN connected NAS drive. Neither LAN connected PC had wrong numbers that morning.

Yes it's really odd. I've never seen anything like it.
You might get the odd duplicate IP conflict but never a spurious subnet.
It's been ok since
Might be the NAS drive has been working hard recently transferring files back to my iMac following getting shot of a woefull El Capitan install!
