Best I can say is that it seemed to happen after a failed connection. It would connect and disconnect a few times and work fine, but if it failed to connect for any reason (mostly mismatched settings between AP and wpa_supplicant.conf) then the bug would occur. So, wpa_supplicant would up the interface, try to connect, fail, down the interface and exit, then the next loop of my script (with a different conf file) would start and wpa_supplicant would be unable to up the interface. Hope that made any sense, because it didn't to me :-) -Zero On Mon, Sep 3, 2018 at 12:48 PM Kalle Valo <kvalo@xxxxxxxxxxxxxx> wrote: > > Stanislaw Gruszka <sgruszka@xxxxxxxxxx> writes: > > > We wrongly use wcid_mask instead of vif_mask > > > > Fixes: 95e444098a7b ("mt76x0: main file") > > Reported-and-tested-by: Sid Hayn <sidhayn@xxxxxxxxx> > > Signed-off-by: Stanislaw Gruszka <sgruszka@xxxxxxxxxx> > > For bug fixes please always try to describe the bug and symptoms.
