|I'm struggling with this wifi card:

I'm trying the 4.18.15 and the very fresh 4.19.0 kernels.
Everything in the interface looks ok, but the scanning fails ***almost*** always. I mean that giving 'iw dev wlan0 scan' gives empty output, except rare and random positive listings. The corresponding 'iw dev wlan0 connect -w xxxxx' gives a timeout.
I don't know how to look for a problem. The firmware is loaded, everything in dmesg looks ok, all the usual checks are perfect. Simply, it looks like I'm on the Moon.
But I am at home.
What can I check?
