USB Tethering. Installation

I’m trying to install NixOS. I using gnome installation iso and I can’t tether my Xiaomi Redmi C10. Bluetooth terhering works well but it so slow

Can’t tether can mean multiple things! I assume that you have explicitly enabled tethering on the phone side. Does ip link list of interfaces change when the phone is plugged in? Is rndis_host module loaded according to lsmod; maybe also cdc-ether?
