I think you can’t change that on any other os. It should be implemented better in the app. You just type/share the ssid and password and the app should trust you that you know what you are doing, and it will be able to connect even if it’s not the network you are currently connected to.
E.g. the shelly app allows this, you can just type any ssid and pw.
Other way I know of: disable 5ghz on the router, connect device, enable 5ghz.
Did you wrote this from your libreboot laptop? As what you wrote is unfortunately true for all devices.
I looked it up for op, this is a lowest end redmi, so no custom roms exist for this unfortunately.
That’s a bit more niche device, no xda page. I couldn’t found any custom rom for that device.
Most xiaomi devices at least have the so called xiaomi.eu rom is available which is basically the same as the original rom, but every chinese only parts and gapps removed. It doesn’t have one as the developer wrote here:
Actually, no. Conditions for a device to be supported: https://xiaomi.eu/community/threads/supported-devices.65673/ Redmi 10C has a 720p resolution, while we only support 1080p and 1440p resolution devices. Please, don’t buy trash devices if you wish to use our ROMs.
So as this is a low end budget device I wouldn’t expect that it will be supported by any 3rd party. If you really want to hack on this device, you are on your own.
With this knowledge I would do the following:
Good luck!
That’s a redmi 9c if that model number is correct. No official lineage support, but there are a lot of interesting roms on xda: https://xdaforums.com/c/redmi-9c.10999/
This seems good, official, gapps is optional: https://xdaforums.com/t/rom-12-1-official-nusantara-project-4-5-unified-for-redmi-9a-9c-9-activ-garden-sinila-updated.4374805/
Afaik if you replace the rom they cant really do much. Also MIUI or whatever they call it nowadays is the worst android experience i’ve ever used.
They track the status on this repo: https://github.com/melontini/bootloader-unlock-wall-of-shame
TLDR:
