Adding support for TPLink EAP-230 Wall

wahlfisch · February 22, 2026, 8:35pm

Hi,
I am absolutely not happy with the stock fw of the eap-230 Wall (rev 1.0), so i was looking for a OpenWRT build for the device.
sadly there is none / found none.

Is there any chance to build one? - i am ready for some testing, flashing, etc.
The device is based on Mediatek. A connection via ssh, and a "dmesg" in the shell shows many messages beginning with "MT7603"...

I was already in contact with tplink support because of some various issues.
They added Firmware signing in their newest firmwares (at least i think so), so you can't get back to older ones. i had problems with their newer firmwares, so they made me some unofficial firmware release to get back to the older ones.

If this unofficial release helps any developer for debuging or building, please feel free to contact me

Seems almost identical to https://firmware-selector.openwrt.org/?version=24.10.5&target=ramips%2Fmt7621&id=tplink_eap235-wall-v1
OEM:

SupportList:
EAP235-Wall(TP-Link|UN|AC1200-D):1.0
EAP230-Wall(TP-Link|UN|AC1200-D):1.0

Might need loader patch to load via web ui

Can you open it (phillips n1 screw near eth port, pcb comes out like a matchbox) and see if there is visible 4-pin ttl header....

I disassembled the EAP - no screws at all
Everything was clipped in the plastic housing.

Looks like that there are some ttl pins on the backside of the upper pcb.
Sadly no through hole connectors - so i have to stable my usb-ttl adapter pins somehow....

So microscopic...

OEM FW os same as 235 wall...
Basic course of action
1/ netboot 235 openwrt initramfs (this needs serial)
2/ apply any minor changes to make it work (presumably none, but you can not tell unless you check)
3/ alter safeloader to add 230 and flash via web

okay - i will try that....will take some time...have to build some kind of pin header mount for placing my ttl -> usb pins on the pcb

any chance to get openwrt via stock fw gui upload?

You'll be the person adding the support, you'll have the opportunity to find out.

Sadly, i have to quit.
the serial pin headers on the pcb are too small.
i've tried to print some kind of clamp to hold the pins on the pads, but my printer is not able to print this tiny holes and so on.
the second difficulty is that the second pcb is blocking this pads on the main pcb. i need the second pcb, otherwise i have no rj45 jack for tftp

if somebody has some better Autodesk Fusion skills or some better ideas, feel free to contact me - i can send the f3d file
