Pro tip: don’t plug your wifi USB dongle into a port right next to your Bluetooth USB dongle, unless you love Bluetooth input lag problems (such as keys getting stuck repeating forever while using a Bluetooth keyboard). Move the wifi dongle around to a different port (like on the opposite side, if you’re using a USB hub board) so the dongles have at least a few inches of physical separation, and everything magically works much better!
