TL-WA850RE not working after update
I recently updated with latest firmware (TL-WA850RE(EU)_V7_211117) and now my repeater is unusable. it is slow, frequently disconnect and reboot.
I'm using in AP mode. Already tryed a factory reset and manual reconfiguration but does't solve.
I would like to downgrade it but it seem not possible (I get a configuration error)
how to solve? any idea?
Here the log
