When a desktop has no wireless at all or a laptop's internal card is too slow, a USB or PCIe adapter is the way out. Nano models sit almost unnoticed in the USB port, while versions with high-gain antennas pull in a signal from a more distant room. PCIe cards such as the Archer TX3000E and TX55E bring Bluetooth into the computer as well. An adapter's speed only helps if the router supports 5 GHz or Wi-Fi 6 too.
