After upgrading the EAP670 from 1.1.1 to 1.3.6 (with OMADA 6.2.0.17) I did lose the AP.

 

After seraching I captured the trafic and find out that the AP use the default IP (192.168.0.254) and don't use the one from the DHCP server.

 

before:

the AP did the following request:

DHCP discover

the dhcp server reply with DHCP offer

the AP issue DHCP request

and the server reply with DHCP ack

 

after:

the AP did the following request:

DHCP discover

the dhcp server reply with DHCP offer

 

and loop on that!

 

I did try a factory reset and it did not change the behavior.

Updated to the 1.3.7 firmware with a laptop on the same ip range (192.168.0.1) but this don't change anything.

 

in all case it send up broadcast on UDP port 29810 with this content (with 1.3.6 firmware):

        }
    }
}

 

A laptop on the same switch port get a correct DHCP IP.

 

What could be wrong ? And how tp downgrade to version 1.1.1 ?

Regards

 

Omada and AP are not in the same vlan. I use dhcp option 138 to allow adoption.
