[SOLVED] how do i know if my desktop doesn’t need a wifi card?

[Fatblabs]

i got a ASUS PRIME Z590-V ATX, ARGB, 1GbE LAN, 2 PCIe x16, 3 PCIe x1, 4 SATA3, 3x M.2 SATA/PCIe motherboard

That motherboard does not have built in wifi, so you'll need to add a wireless card.

Yes.
That is better, faster, more stable than any WiFi.

if WiFi is a must, there are many USB adapters, get one with an antenna.
