Mine will only connect if I disable WPA2-PSK [AES], and leave it with no security. I have tested this on an isolated vlan. Works perfect with no security, as soon as I enable WPA2 I get the endless flashing blue light. Using TP-Link Deco M9 Plus v2.8 with the latest firmware (1.5.6 build 20211018 release 35617) and the latest firmware on the base station (4.16.3.117). Anyone have any suggestions? Thank you in advanced.
Edit: I should also note that my Deco’s are in AP mode only. I am using pfSense for everything else.
