EAP-225-outdoor v3

Hello, I'm new to this and have a problem. I have the EAP-225 v3 outdoor access point, and I don't know how to install the OpenWRT firmware. The guide says it can be done through the manufacturer's interface for version v3 and later, but it doesn't work. What can I do?

[Moderator edit: fixed the model number to eap225]

Can you confirm the model you are using? I see support for the 225 but not the 255.

Yes, the TP-Link EAP-225 V3

Ok. Good.

Did you follow the directions exactly, including the ssh commands?

What file did you try to use and what happened ehen you attempted to get it to upgrade to openwrt?

Also, what version of the vendor firmware is currently installed?

You have version 5.1.1 of the firmware on your TP-Link EAP255-Outdoor v3 Access Point. You've successfully stopped the cliclientd service using the cliclientd stopcs command, but when you try to install the firmware, it says the filename is too long. You tried changing the name to factory.bin, but it didn't work.

The instructions mention firmware 5.0.3. Can you roll your vendor firmware back to 5.0.3 and try that?

Kateryna cannot install version 5.1.1 of the firmware on her TP-Link EAP255-Outdoor v3 Access Point because it's no longer available. She can only downgrade to version 5.0.8.

Did you try with the downgraded version?

The old firmware appears to be available here:

Does anyone know what happened with this? I have EAP-225-Outdoor V3 with version 5.1.1 of the firmware. I want to use my EAP-225 as a client to access a POE camera which must be reached wirelessly. After reading this thread, I'm not sure whether to try upgrading to OpenWRT with the installed version 5.1.1 or to try and drop back to 5.0.3. Any advice would be appreciated.

If anybody is still interessted, I managed to flash OpenWRT on the EAP-225 v3 outdoor today.

After cliclientd stopcs I had to start the update twice (no idea why...). Now I am on a fresh install of OpenWRT.
