Do you have a Broadcom bluetooth chipset and did you recently install the Windows 10 Creators Update? I have read some articles about issues with that, but the same articles say that Microsoft supposedly blocked the update for people they believe would have a problem. It is still possible to manually install the update though according to what I've read. I don't use wireless for gaming. I use a wired keyboard, mouse, and ethernet connection, so I can't add much else unfortunately. Your post is lacking in any details like PC model, OS, bluetooth chipset, keyboard and mouse model, etc.
