This can be verified by running iw list and looking at the supported channels.
The /data/misc/wifi/wpa_supplicant.conf file does not seem to take effect when trying to specify frequencies, for instance (for 5 GHz channels 36, 40, 44, and 48:
country=ch
ctrl_interface=/var/run/wpa_supplicant

network={
    ssid="my-ssid"
    bssid=00:00:00:00:00:00
    freq_list=5180 5200 5220 5240
    scan_freq=5180 5200 5220 5240
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk="my-pwd"
}

The only way I found to connect to 5 GHz is to disable the 2.4 GHz radio entirely on the router. Otherwise, the connection defaults to 2.4 GHz.
On the router, it is also better to set a fixed channel (e.g., 36) rather than letting it be automatic. In auto mode, the robots could not connect systematically to the network.
Note also that my question was wrong in the sense that the hostapd.conf files are used to generate the access point, not to connect in station mode.
These are maybe considerations that could be added to the technical doc @Chad-Sweet ?

So nothing changed, just unplugged and plugged back the tof camera and reflected the changes by configuring the camera server accordingly, weird...

[  390.539854] R0: [VosMCThread][02:38:25.067557]  wlan: [3231:E :PE ] limProcessAssocReqFrame: 914: Max Sta count reached : 2

Changing max_num_sta in hostapd.conf did not help.
After doing a little bit of digging, it seems like this may be a hardware limitation of the wifi hardware on VOXL1 in SoftAP mode : https://android.googlesource.com/kernel/msm.git/+/android-msm-bullhead-3.10-n-preview-1/drivers/staging/qcacld-2.0/CORE/MAC/src/pe/lim/limProcessAssocReqFrame.c#847 .
It could also be a setting somewhere low level and unfortunately we don't have any information on that. Sorry about that.
The wifi module on VOXL1 is QCA6174.

Thanks so much for clarifyiing this for me and I take it you wouldn't suggest using it since it's an older part?

My only suggestion is to use the ICM parts since that will always be installed on our boards, and you'll have no software mismatch builds across platforms old and new.
It's the Bosch parts that have fallen out of favor lately in the market and were also very hard to get last year hence the move to start DNI'ing them.
Thanks!

just to give a little update here:
I found out how to set the "force mavlink mode" variable in the voxl-vision-hub.conf which was forcing the parameter back in PX4, and simultaneously set it to "Normal" in PX4.
So far I don't see any downsides from using MAV_1_MODE=0 (normal).
I'm only making use of voxl-mavlink-server and voxl-vision-hub for the time being, basically to use VOXL's connectivity to send MAV commands to the PX4.
Do you think using "normal" will have any downsides?
The inconsistency between your documentation and the .conf and PX4 firmware files still exists though, so I'd really like to get some more insight on this.
Thanks and a great weekend to everyone.

Not that big of a deal. Has the bug been fixed where sudo reboot takes a couple of minutes to actually reboot the VOXL2? Each time I want to reboot the Pixhawk it's about a 5 minute process
