I've found that using a short usb extension cable with those wireless dongles, rather than plugging them directly into the computer, works loads better and fixed "lag" issues for me. Maybe some kind of EMF interference?

there is an interference from usb to 2.4ghz devices

Also, try using a USB2 port instead of a USB3 one.

USB3's high speed produces EM inference with some receivers.

I can partially confirm: 2.4ghz, or at least the common USB mouse implementation, is very susceptible to interference, it's sent me down a few wild rabbit holes with my Basilisk v3

Same thing helps with USB Zigbee interfaces that use 2.4GHz.

It seems most-useful to make sure it is only a USB 2 cable, without the extra USB 3 data lines.

(USB 3 makes a ton of noise at ~2.4GHz. They could have spread out emissions and dialed them down, but they stuck them in the same trash band that microwave ovens [and mouse dongles] use because... well, it's cheaper and easier that way.]
