I’m really interested in building/making my own router. I need help with which network card to buy. I wanna use it as a regular Wireless Router. I want it to have fast & seamless streaming for many devices. I need ones with antennas for great streaming. Thanks
I wouldn't recommend using pfsense for wifi, you're better off with a separate access point.
But if you go to their website there is a link to the hardware support list. Just make sure you get a wireless card with a chip from that list.
