EAP225 V3 - No DHCP after openWRT 24.10 upgrade

Installing and Using OpenWrt
1

Hello folks,

Hope you can help me out. I just got a tp-link EAP225 V3, stock firmware was working fine. I then followed instructions on the wiki to upgrade to openWRT firmware; it all seem to go in order.

However, since upgrading to openWRT, I am unable to reach the AP. It doesn't assign an IP to a laptop when connected; there is no SSID broadcasted. I've tried setting the laptop to static IP (192.168.1.100, 192.168.0.66) but I cannot find the AP (192.168.1.1, 192.168.0.1). The LED sequence when booting up seems to be as expected: blink orange briefly, then solid green for ~5 seconds, then blink green really fast, then blink green slow, then solid green.

Router Details OEM
Type: Tp-Link 225 V3 with stock FW version 5.1.10

OpenWRT Details
Uploaded FW version file name: openwrt-24.10.0-ath79-generic-tplink_eap225-v3-squashfs-factory.bin via the web interface.

Would appreciate any / all advice. Thank you very much

It is normal default post-install state that all radio is off unless you set the country code and enable the,m The only ethernet port is "LAN" which runs dhcp on 192.168.1.1
Do you need help with steps?

Hi,

Thank you responding. Understand that the radio's are off by default when first upgrading to openWRT. However, the issue I have is that I am unable to reach the AP, from a laptop running Linux configured in different ways (below).

Attempts:

  • Connect laptop set to automatic IP (i.e. receive IP from AP DHCP): FAIL, the laptop never receives an IP
  • Set laptop to static IP (192.168.1.100), then
  • Ping 192.168.1.1 : FAIL, unable to reach destination
  • ssh root@192.168.1.1.: Fail, unable to reach destination
  • Set laptop to static IP (192.168.0.66), then
  • Ping 192.168.0.1 (or .254) : FAIL, unable to reach destination
  • ssh root@192.168.0.1 (or 254): FAIL, unable to reach destination

I don't know what else I can do to reach the AP. I've tried power cycling the AP, tried pressing reset for > 5 seconds. The LED sequence during boot up seems to indicate the AP is booting up correctly (orange blink, solid green, fast blink green, slow green blink, solid green), however, I am unable to reach it.

Any help would be much appreciated!

Try to press reset button when the "really fast" happens.

Hi,

Where can I find instructions on the type of serial (not sure if it requires soldering), baud rate, parity, etc ...? Thank you

Hello,

Thank you everyone for the help offered. I figured out the problem: I was using the openWRT factory image for V3 of the router, but it turns out it was V4 :person_facepalming: . Was able to upgrade FW to openWRT successfully on a different unit (the other one is bricked, didn’t attempt to recover) once I had the correct version.
