@Kim-Nyholm I think iw and iwinfo are not working as expected due to WARP CORE (the Onion Enhanced MT7688 WiFi Driver).
Check the '/tmp/dhcp.leases' file that lists all the devices which connected to that AP so far (in the last 12 hours - it's the default lease time).
If you want to know only the number of active clients then flush actualize the arp cache in some way.
@György-Farkas Interesting, I did check on an Omega 2+ running 0.3.2 b200 and executing the command did nothing. I power cycled it, and the LED blinked through the start up pattern but the Omega-XXXX network never appeared. Now that Omega 2+ will not even start and has discoloration on the shield near the U.FL port.
I just reran the commands on an Omega 2 running firmware 0.3.2 b222 and it worked! There was no lag when the local wifi router was disconnected. Thank you very much!
Thank guys I took a look at the note and ordered a few different units to test.
My preference is really to have 5GHz built into the the Pro or a version of the Pro. Purely from a mechanical point of view, my IoT device exposed the mini-usb port on my case so users can power the device, this would mean I have to also expose the USB-A port with the 5GHz dongle which looks pretty messy and I know users will unplug it or fiddle with it and then complain they have no network connectivity. Alternatively I would need to redesign my case to move the Omega away from the side of my case and use a short mini-usb case mounted port. Either way it's messy.
