Iphone X WiFi problems

[beerglass007]

Upgraded from a iPhone 7 which I've had a year and now using iPhone X

The wifi hasn't changed in my house but its awful with my iPhone X now

It never connects and keeps dropping back to 4G

All other devices like TV, MacBook, iPad all perfect but just the iPhone X

Has anyone had these problems or is my phone faulty

Thanks
