Tags: #Network Connectivity #Firmware Update
Model: EAP223  
Hardware Version: V2
Firmware Version: EAP223(EU)_V2_5.1.10 Build 20241023

EAP223(EU)_V2_5.1.10 Build 20241023 (I believe) is the version and following the attempted update, the controller reported it had failed to reconnect. 
The EAP is crashing(?) cycling the LED: off,amber,off,green. Then after about 5 seconds repeat.  
It is not showing as a client on the gateway and there is no WiFi from it. I have no way to get to it to downgrade/reload. 
Is it bricked? Can it be reflashed?

Hi  @Mick3000 

 

It seems like the EAP is bricked.

You may contact your retailer to check the warranty.

Hi  @Mick3000 

 

To be more specific:

1. The EAP was using the firmware 5.1.10 Build 20241023, and the controller pushed a new firmware 5.1.11 available. Then, you click to update the firmware. Is this correct?

2. When updating the firmware, was there any power outage for the EAP? Or any other accident?

 

 

Please refer to the following guide to try to recover the firmware for the EAP and let us know if it helps.

1) I don't know the version before upgrading. It was the version shipped to me about a month ago and it was working fine. Yes, I selected to upgrade from the controller. 
2) There was no power loss or internet loss at the time. I had also updated 3 POE switches and two EAP235s without iss

  @Vincent-TP Hi

maybe I missed the recovery mode on the website. I tried to follow the downgrade instructions but that requires a connection via lan. But this is not getting seen on the LAN. It doesn't seem to get an IP address from DHCP on the gateway. 
I tried the 15second reset to factory but it carried on crashing through that
is there a lower level recovery mode?

Hi  @Mick3000 

 

EAP223 had a default IP adderss 192.168.0.254.

Please plug a PC into its LAN port (like below), and give the PC a static IP address 192.168.0.100, ping the IP address 192.168.0.254, see if it replies.

 

How to use the Ping command

 

If yes, please refer to the situation 2 to login the EAP's web interface:

How do I login to the web management page of the EAP Series products (Standalone mode)?

 

And try upload the latest firmware:

Thank you  @Vincent-TP 

Unfortunately, it is unreachable on a ping from the same subnet

Hi  @Mick3000 

 

Upgrading firmware is not a tech thing. Just make sure the power is stable during the update. 

 

This is a guide for your reference:
