I've to confess I've no clue, but I guess the answer is "some of them":
Here in ETH Zurich (www.ethz.ch) I'm in an environment with a lot of
surrounding APs (probably 7 or more seen with the same ssid).

Applied, recompiling, will test tomorrow.

I'll soon (Friday) leave the environment permanently,
thus testing will not be easily possible anymore.

If this issue is 5Ghz related only, can I somehow trigger it without an AP
running in that band / i.e. make the card try to use the 5 Ghz band although
there is no ap nearby?

Cheers,

Nico
