Low wifi connectivity when booting up

[WPCentral Question]

I'm using a HP r046tu laptop windows 10 which I updated it. So my problem is when every time I'm going to boot my laptop to use it. My wifi connectivity is too low and it doesn't show any available routers here in my house. Pls help me to fix this problem. Note that I've updated all my drivers as well to the Windows 10.
