I unfortunately cannot connect through Ethernet, how can I get the best connection with WiFi? I heard the WiFi onboard motherboards is not as great as buying a separate adapter? What would be the best adapter? Thanks.
WiFi built into the motherboard and a pcie WiFi card are going to be pretty much the same. USB WiFi adapters are going to be bottlenecked to the speed of the port.
You would want any WiFi 6E pcie card if you don’t already have the motherboard and a free pcie slot. Also make sure your router also supports WiFi 6E.
Which motherboard do you have?
