Next issue with beta release 4.8.3 (at least with this one there is an indication).
Uplink connection goes back to US or JP, specifying higher 5GHz channels as possible. (149-165) . Those are not valid for Europe. When setting the correct country code in the Wireless LAN interfaces, it is adjusted. Until you loose the uplink connection, then it goes back to the US/JP default channel list. And in Europe none will be found.
When the wireless radio is set to the correct country (in LUCI), then it adjusts to usable channels. At least for a while.
