ifconfig wlan0 up
iw wlan0 connect -w Inpeco-test

Then, to ping, you need to set your IP address, either with a DHCP
client or statically.

We currently use level and high with one shot as default.  There are
some platforms that use rising, though, so we have a platform_quirk

You could be missing some interrupts by using rising and this could be
the reason why you don't see the SSIDs consistently.
