Lost Wireless UPLINK

Hello,
I have a mixed EAP610 V1 (2 devices) and EAP 225 Outdoor (4 Devices).
First EAP610 is connected wired to the OMADA OC200 controller.
Other EAP are connected Wireless
Last week, the Omada Controller prompted me to upgrade the firmware from version 1.4.2 to 1.4.3. However, after the upgrade, I started experiencing continuous disconnections between other EAPs and the main uplink
Now I downgrade to version 1.4.2 and seems to be more stable .
Now I have
- EAP 610 with firmware 1.4.2
- EAP 225 with firmware 5.1.11
What is wrong ? This version have problems ?
In the past I get some disconnections only between the 2 EAP 610 normally the EAP 225 stay connected.

As MR.S mentioned, the mesh signal is really weak. Given the weak mesh signal strength, the situation you reported are completely normal and practically unavoidable.
Having one uplink EAP support four mesh EAPs is pushing the limits. That's exactly why I recommend finding ways to install additional Ethernet cables.
In the meantime, you may consider:
1) Move the Mesh EAP closer to the uplink EAP;
2) Avoid obstacles and wireless interference between the uplink EAP and mesh EAP;
3) Change the channel of the uplink EAP, please test on different channels;
Can I use this firmware ?
This firmware is not the latest, you can update to the 5.15.24.

Do you have one wired EAP and 5 wireless EAP meshed to the EAP610-outdoor? Would you please share a screenshot of the topology of your network?
If possible, please try to use Ethernet cable to wired connect to one or two EAP units to make the mesh system more stable.
BTW, here is an pre-release version for EAP610-outdoor, you may update and see if it helps:

Hello I Have a OC200 as controller and seems that have Omada V 5.15
Can I use this firmware ?
yes I have 5 Meshed AP and I cannot pass cables between the structures.
Now I reach a stability with firmware 1.4.2 on 610-Outdoor and this configuration but One ap result offline and I must go to remote structure to reboot it.
Before I Set a preferred Uplink to NibliExt for some AP but Yesterday was not stable.
The NibliInt is Wired Connected to NibliExt

All EAP225-Outdoor access points have too weak a signal, it's almost strange that it works at all.
The only Access point with acceptable signals is the EAP610-Outdoor

Thanks for support.
This is a public park and I cannot pass ethernet cables, I hope in the future, but for now no.
With this situation (Firmware version 1.4.2 on 610) seems to be stable
Next time I go to the park I try to upgrade Omada Firmware (from remote seems not work).
I change some uplink and now is that

You may want to take a look at the following outdoor Wi-Fi solution. Hope it can give you some hints to optimize the installation:
