Hello p150,
There are many things that can be affecting the performance on your system.
Please try the following:
- Disable the uAPSD. Refer to this link:

- Check the antennas inside the computer are connected in the correct way.
- Open CMD as administrator and run the following command: netsh wlan show interfaces
This will display a lot of information and will show the signal of the wireless LAN.
- Change the Security encryption of the router. Here you can find more information:
