Yes, and I just replace the ER7206 beta with the official firmware ER7206(UN)_V1_1.2.1 Build 20221026.

Dear @crrodriguez,

Note this firmware does not appear to support the newer features of the 5.6.x controller, for example "The gateway does not support mDNS" is shown when you attempt to enable it.

 

Please ensure that both your controller and gateway have been upgraded to the controller v5.6 firmware.

 

Note:

The official firmware ER7206(UN)_V1_1.2.1 Build 20221026 is adpated to controller v5.6 and fixed the DHCP issues.

  @Fae 

 

Think i found a bug with the 20221025 and 20221026 ER7206 firmwares (1.2.2 beta and 1.2.1 official)

 

L2TP VPNs work for resource access work fine, but if the VPN is set to use the remote gateway to tunnel traffic - they fail and there is no traffic.  Flashing back to Sept 2nd 1.2.2 beta immediately resolves the problem

 

 

EDIT: resolved this with a factory reset and reconfig

  @Fae  Hello! Isn't the new firmware immediately available via the Omada-Update? I have a ER7206 V1 (Germany) and it says that the firmware is up to date (1.2.1 Build 20220512 Rel.77113).

 

My OC200 has v5.6.4.

@Fae I have major issues today with ER605(UN)_v1_1.2.2_Build 20221015 (Beta), after running my weekly schedule reset the ER605 didn't want to provide IP address to my client, I could see then connected buy IP address were either blank or invalid range 169.X.X.X. 

 

I tried to do a factory reset 3 times, and after adopting it still same behavior or get stuck in configuring step. 

 

I connected a cable directly to the ER605 after a 4th time factory reset and before trying to adopt it in Omada and it worked fine, I was able to login, get IP and internet to that PC that I connected directly.

 

I had to go back to 1.2.2 Build 20220902 Rel.35926 and I was the only way to get it adopted again by Omada and working fine.

 

I am running the latest firmware 5.6.4 in my OC200 v1.20.1 Build 20220921 Rel.35880

  @Fae Major problem. After upgrade to Nov 2nd beta firmware (ER605 v1) 24 clients from 79 didn't get IP. I try to reboot, forget, renew, set the lease time to 2 min but no IP by DHCP. Er605 reboot 3 times, power off and on no luck. Try to power cycle devices some get IP some no. I have to downgrade once more to solve the problem.
