Apex does not want to DHCP

[Mr31415]

I have just purchased a new Apex unit, configured it for DHCP On and restarted it using the Restart command. My previous Apex would acquire a DHCP lease without issue. This new device is stuck at 192.168.1.50, the statically configured IP. My DHCP server even shows that it tried to acquire a lease, but it is like the controller discarded the result:

Jan 4 20:07:35 dhcpd: DHCPOFFER on 192.168.1.35 to 00:1c:11:22:1d:49 via em1
Jan 4 20:07:35 dhcpd: DHCPDISCOVER from 00:1c:11:22:1d:49 via em1

Did you actually reboot the Apex, or just do the network restart?

Is that the whole transaction? No DHCPREQUEST packets logged?

Interesting... the OUI part of the MAC address you listed is registered to Motorola. My Apex's MAC OUI is registered to Nippon Dempa. What is in the path between the Apex and the system running the DHCP daemon?

 

[Mr31415]

Network restart. No DHCPREQUEST, thus the offer got ignored. No I fiddled with the MAC address for my own paranoia.

The Apex is connected via an Airport Express which is joined to my wireless network.

LOL! Well, that explains the single character difference.

Reboot the whole darn thing and see what happens.

Completely turned off power to everything, then restarted it - no network access at all. Had to go in the display and do a network restart again before I had access on the 192.168.1.50 IP again. No DHCP DISCOVER messages this time - nada.

Remove the Airport Express from the picture by connecting the Apex directly to your router or switch (I just have a hunch that you might have a switch in addition to the router ).

I doubt that the Express is the problem, but it's a logical next troubleshooting step.

If you still have the DHCP issue, reload the Apex firmware while you still have it wired directly.

Yeah that was my next step. I am sure it is the Airport Express as it is in bridge mode. Think it does not relay the DHCP requests from the ethernet port properly. Ah well I will just use it in static IP mode for now. Thanks!
