hello,
I'm trying to set up a raspberry pi 3b+ as a simple wifi repeater. I've got the recommended build
(OpenWrt 21.02.1 r16325-88151b8303) for the rpi3b+ up and running with luci and travelmate installed. So far everything seems to work fine except for one thing: the device refuses to switch to AP-STA mode, despite being capable according to iw list. Whenever I activate the AP-interface, the client interface(uplink) gets disconnected and disabled.
I'm honestly not even sure where to start looking. Before I dig deeper into this, does anyone know if this is a known problem with the pi3b+? Has anyone ever gotten ap-sta to work on this model? Google only takes me to lots of unresolved problem reports like this one: https://forum.openwrt.org/t/how-to-configure-raspberry-pi-3b-as-a-repeater/46202
