General discussion • Raspberry Pi as LTE router

Hallo everyone
I want to build cheap LTE 4G router.
I have Raspberry Pi 4b 4GB RAM + T77W968 DW5821e eSIM with USB adaptor which works great in Windows 11. I could buy USB 6e adaptor compatible with Pi.

I've ended up with having high end intel Killer AX1690 WiFi card in my PC and realising it can only support 2.4GHz or 5GHz not 6 GHz and only one frequency same time - like 2.4GHz only for my smartHOME devices because after some deep digging Windows only supports just one frequency at the time - maddness.

Will I be able to use 2 frequenies in Raspberry Pi like 2.4 and 6GHz same time if I buy USB 6e card?

How to install all drivers?

Currently I use Pi for PiHole only without graphical interface - is it easier if I would install one?

Thank You for helping me.
