If you built it and the problem is mainly related to your PC, here are some suggestions:
- Try to buy a dongle with a Broadcom chip inside.
- Try to update the dongle's drive to the latest version.
- Try to move your dongle a little bit close to the keyboard.
- Try to buy the dongle from a larger, well-known brand, their dongles usually have better compatibility.
- Buy the dongle from somewhere you can do fast exchange like Amazon because you might need to exchange it.
