Witam,
w ręce wpadł mi taki model APeka. Udało mi się skompilować oraz wgrać openwrt w wersji 18 ale mam problem z podniesieniem interfejsu sieci bezprzewodowej 5Ghz. Przeszukałem kilka forów i nic. Solucje tam podane nie pomogły.
A dokładniej, chip jaki jest to QCA9882. Dostaje w logach uruchomieniowych:

I wiem, żeby się nie kierować monitami o ładowaniu firmware. Ale może ktoś ma jakiś pomysł.
