I have the same issue with 2 EAP225 V3 and to me it looks like the firmware changes from TP-link disabled the possibility to change to OpenWRT. The shell also shows a typo in the welcome message - YOU ARE USING EAP CLI SYETEM
One can enable a so called advanced permission mode using the enable command but still the available commands are very limited.
I could not figure out a way to elevate the rights further.
Does anyone now if TP-Link closed this on larger scale for their devices after certain version upgrades?
