Windows 10: Only 1 device is slow on a WiFi, but is fast on other networks

Greetings,


I have a very strange issue with my laptop.

It is a fresh install of windows with the latest updates.

The problem is that when connected to my home WiFi I cannot get more than 15-20 mbps speeds.

Other devices get the full 90-100.

At first I thought that it is a problem with the laptop itself so I tried to reinstall the wifi drivers and update them but it did not help.

Then I connected the laptop to another network and it ran fine, up to the full speed of that network still wireless, around 60 mbps.

The issue is only with this my laptop connected to the home wifi.

If I connect via LAN to the router then I get the full speed.

As I said above it is a fresh install of windows and I have installed only 2-3 programs that do not alter network speeds.

I am open to any suggestions or advices.

Thank you!


Regards,

Veselin
