Hi,
so, If I take the WiFi scan sample from the nrf/samples/wifi/scan folder, and flash it to my board, I can reliably see my created hotspots, no matter if they're 2.4GHz or 5GHz.... and I can connect to both instances of the hotspot with the nrf/samples/wifi/sta sample. So, I would say hardware is ok. But, my code in my project can reliably scan and "see" 5GHz network, but, I can only connect to the 2.4GHz instance of the hotspot.... 5GHz can see the network, and, when I try to connect, it say's the that the access point isn't found.
[00:01:03.225,708] <inf> scan: 1 | test_hotspot 12 | 11 | -21 | WPA2-PSK | 3E:6E:2D:12:E7:CC
[00:13:40.635,681] <inf> scan: 8 | test_hotspot 12 | 161 | -51 | WPA2-PSK | E2:29:7A:21:D0:68
These are the logs from my app:
[00:00:08.982,788] <inf> wifi_module: WiâFi connection initiated to 'test_hotspot' [00:00:15.006,744] <inf> wifi_module: Net event: 3512074243 [00:00:15.007,080] <err> wifi_module: Wi-Fi connection failed: access point not found.

[00:00:34.476,135] <wrn> wifi_module: Unsucessful connecting to the WiFi, failed 3 requests.
This is my prj.conf, can you please check and see if there' something that's not ok? I also embedded my code for connecting to the Wi-Fi....
