after installing new windows wifi adaptor gets signal so weak while it's so close to the router

[Atousa-kh]

I've installed new windows (10-64) after that the wifi adapter has been so weak and while it is so close to router but seams to far and does not sho evet one line of signal. my laptop model is hp pavilion 15 notebook pc. I wanted to try component test but there there was not any component test or wireless module test only hard drive test were existed. I've uninstalled the adapter and installed it again, tried roll back too but nothing changed. does reinstalling windows work?

See if this driver resolves the problem:

Broadcom Wireless LAN Driver (Windows 10)

7.35.351.0

That would be the only suggestion I can offer.
