Set band of Hotspot to 5GHz

Design
#1

I discovered that 5GHz wifi 801.11 offers better performances at low ranges and in places with Bluetooth interactions.

I configured my device (Xperia 10 ii on SFOS 4.5.0.19) in this way:
Hotspot configured:
5ghz selection on the wlan0 device: iw wlan0 set bitrates sgi-5.
I’m still testing it because sometime it gives me “operation not supported” but as soon as this become 100% this can become a wiki,

Hi, that’s the issue I have when I do the configuration via command line (you can find the full description in the first post).
I’m now ispectioning the configuration file for the hotspot and bridging SSID: I hope I can set there the band for the SSID when created.
So far I not found any file like on other distros /etc/network or files like
/etc/NetworkManager/system-connections/SSID_CONFIG_FILE
where to place “band = a” option

Any suggestions?

I made some progresses:
I installed very old package connman-test.
In the folder /usr/lib64/connman/test I modified the relevant executables with nano (or whatever text editor is available) by replacing python with python3 in the first row:
#!/usr/bin/python >>>> #!/usr/bin/python3

enable-tethering works: you need only to do it with wifi “on” and not connected to anything.
Now I added to “enable-tethering” file the following command just before “return tech_type”:

                tech.SetProperty("FrequencyBand", "5GHz")

This command run without errors but the SSID created was still in 2.4 ghz.

I’m starting fearing this is not something in the OS but hardcoded in the android baseline or even in the kernel.
