TP-Link EAP225 V3 not reachable after OpenWRT Install

Installing and Using OpenWrt
1

Hello,

I installed the latest OpenWrt firmware on my TP-Link EAP225 v3 using the TP-Link web interface. After the update, I am no longer able to access the device via web interface or SSH.

My setup / what I have tried:

  • Device: MacBook or Raspberry Pi 3B (Linux) (to cancel out problems with apple...)
  • Both are configured with static IP: 192.168.1.100/24 (but not connected at the same time)
  • Connection: PC → PoE injector (802.1af - included with AP) → Access Point (no other switch/router in between)

I cannot reach the AP at 192.168.1.1. I also connected the AP to a DHCP network but no address is assigned.

Additional observations:

  • Failsafe mode does seem to work but does not have any effect (LED blinks yellow very rapidly)
  • Normal boot sequence: blinking green → brief yellow → then solid green

At the moment, the AP ends up with a solid green LED, but remains unreachable.

Has anyone encountered this before or has suggestions on how to debug or recover the device?

Thanks in advance.

based the LED, it does sound like failsafe's been triggered - https://openwrt.org/docs/guide-user/troubleshooting/failsafe_and_factory_reset.

seems you're not the only one with Apple issues - Reset EAP255 v3 running OpenWRT? - #11 by yw71sovr (although the thread is about EAP255).

yep - exactly because of this I also use the raspberry pi 3B (seen this post ^^)

but even on the raspi it is not reachable.

if you're 100% certain your hw config is correct, try serial.

I tried but I can't find the RXD and TXD Pins on my board :confused:

I think my hardware is correct -

I have a TPLink V3, my network adapter is an Atheros AR8033-AL1A (not the one specified in the TP-Link EAP225 entry).
My firmware version was 5.1.1 (>5.0.3) and I have installed the openwrt-25.12.1-ath79-generic-tplink-eap225-v3-squashfs-factory.bin via the webinterface.
Befordehand I disabled the firmware check via ssh.

before flashing the firmware my managementport was on vlan 101 and I had configured multiple vlans - this can not interfere with the firmware flash or am i wrong?

whatever was configured, is now gone.
