Does the card was installed in the laptop by default? If so what is the model of the laptop? > Linux test4 4.17.0-rc7+ #5 SMP Mon May 28 12:35:22 CEST 2018 x86_64 GNU/Linux > > Seems iw scan works correctly and first assoc.

So, I would check if send IEEE80211_TX_CTL_RATE_CTRL_PROBE frames with qsel = MT_QSEL_EDCA would help. Another thing to try is checkout vendor driver and see if there is need to add extra code if device is_mt7612() . Regards Stanislaw
