hello,
I have a same setup for (at least) 3 years now: Mikrotik hAP ac lite <USB> Android Mi A2 and then I enable USB tethering on the phone. For some reason now on phone USB tethering is disabled (grayed out).
Additional notes and what I tried:
USB cable is good, if I connect to PC “tethering” is enabled
during previous working time and now I lend MT to I friend and he updated it to v7
before that I also made a backup of my setup
FWs I tried (nothing works)
v6
v7
v7 beta
On phone a see that last update was in 2021 and there is no other updates
also phone was completely restarted/formated
Any ideas what else I could try or how can I debug
