Model: EAP245  
Hardware Version: V3
Firmware Version: 2.2.0 Build 20190530 Rel. 56122

Setup: two EAP245 V3's and an EAP225-Wall V2 managed by a controller running 3.2.6.

One of the EAP245's has never been stable after updating the firmware. If I remember correctly it had 2.2.0 Build 20190530 Rel. 56122 out of the box and while another identical EAP245 bought at the same time has run several versions up to the current latest (2.4.0 Build 20200117 Rel. 39932) the problem unit can be upgraded but will drop wifi and not pass DHCP client requests (probably other network services are broken but it's connected so briefly that it's hard to tell).

Both EAP245's have exactly the same configuration.
I have tried factory resetting the problematic unit and re-adopting but it's still them same.

 

The firmware upgrade itself works fine. When it reboots clients will connect for a few seconds then drop. I can sometimes get a slightly more stable connection if I allocate a static IP address.

I've raised a ticket with TP-Link UK support but with the craziness going at at present I'm not sure when it will be answered so I thought I'd try the community for some ideas.

@sportq 

 

From the title and the description, I know your EAP is running the firmware 2.2.0 Build 20190530 when you bought it, and it can work well. After you upgraded the firmware, you found the clients connected to this AP cannot get IP address. But another EAP245 can work normally. Yes?

 

Did you set VLAN on your network? We have change the VLAN mechanism in the new firmware, it may have an effect on your network if you don't set the VLAN correctly, so please check it.

It would be better if you can tell us the network topology, which may be useful for us to troubleshoot your issue.

@forrest I have 3 VLAN's 1,20 (guest wifi) and 107 (IoT devices). All the EAP's are provisioned identically from the same controller. I've been through the settings for the both the EAP245's, the one that continues work after 2.2.0 and the one that doesn't, they are identical.
