First things first, I bought a Gaming PC with Wireless mouse and keyboard. The PC is:
CPU: Intel Core i7 6700K @ 4.0 Ghz
GPU: MSI GTX 1080 Gaming X 8 Gb
MB: Asus Z170-A
RAM: Corsair Vengeance LPX 2x8 Gb 3200 Mhz
PSU: Corsair RM750, 80+ Gold
CASE: Phanteks Eclipse
With it bought a WiFi dongle, cause getting a Ethernet cable is not an option for me.
Installed win 10 64 bit on it, the internet worked perfect the first day. But before going to bed and shutting off my PC, that shitty win 10 update happened and the wireless connection was never the same...
The next day, while turning the PC on, it finished its update and wow boy, did that internet keep disconnecting or eventually dropping to 10 kbps. However, now, about a week after, I've noticed the problem is actually with the damn interference with the Wireless mouse and keyboard, even though it worked perfect the first day using this shit, I even managed to download and play CIV VI just fine. I noticed that the internet keeps dropping from 5 MB/s to 10 kbps while moving the damn mouse or typing on the keyboard. If I stop using them and get away, I notice the inevitable growth of internet downloading speed. So guys, how should I fix my problem, considering I don't want to buy a wired mouse&keyboard (mostly because I've spent already too much money on my PC).

If you're interested, my WiFi dongle is TP-link TL-WN823N.

Most are (there are the odd few which are 900 MHz). 2.4 GHz is a very crowded frequency. Bluetooth is also 2.4 GHz. Microwave ovens also emit in this frequency range. And unlike WiFi, none of these will let you choose the 2.4 GHz frequency band, so interference is almost inevitable.

What *might* work is to buy a USB extension cable. Plug the mouse/keyboard wireless dongle into that and put it on your desk right next to your mouse and keyboard (or tape it to the bottom of the desk). Hopefully the reduced distance means they don't transmit as strongly, and don't interfere with your WiFi. (If that doesn't work, try it with the WiFI dongle at the end of the USB cable. Tape it up against...

Ok your wireless mouse and KB will be Bluetooth not 2.4 or 5 Ghz Wireless, I would suggest deleting the dongle from device manager and select delete driver software. Do the same for the KB and mouse, you may need to temporarily connect to the internet via cable to allow Windows to locate the best driver from the online driver store.

Hopefully the reduced distance means they don't transmit as strongly, and don't interfere with your WiFi. (If that doesn't work, try it with the WiFI dongle at the end of the USB cable. Tape it up against the wall where it has minimal obstruction to the router, and away from the mouse and keyboard and their wireless dongle.)

If you really want to use WiFi without interference, you're going to have to suck it up and buy a 5 GHz router and 5 GHz WiFi card. The dongles are more for laptops, which need to be portable with the dongle plugged in. A WiFi card will come with an antenna which gives an order of magnitude better range and reliability. This is more important for 5 GHz because the signal attenuates more quickly through the air and obstacles than 2.4 GHz does.

5 GHz has 15 non-overlapping channels, vs just 3 for 2.4 GHz. So there's much less chance of interference on 5 GHz.


Nooooooooo. Windows 10 is terrible at finding the best driver online. Win 10 will often substitute Microsoft generic drivers. It seems to consider these "better" than manufacturer-provided drivers made for Win 7/8 but which work just fine in Win 10. Roughly half the support calls I got from clients who took up Microsoft's offer of a free Win 10 upgrade were due to Win 10 replacing a perfectly-functioning hardware driver with a generic Microsoft Win 10 version which didn't work. (Mostly printers, though network cards were the second.)

Go to the manufacturer's website for your mouse, keyboard, and WiFi dongle. Download Windows 10 drivers from there and install those.
