Internet performance is choppy

HP 17-002ur

Windows 7 64bit

 

The Inteternet works not very well. It periodically freezes (crashes) and I need to "reconnect" my connection. Only the speed falls, it slows down. Connection status don't changes. I have not this problem on other computer and other devices.

 

Realtek RTL8723BE 802.11 bgn Wi-Fi Adapter   (if i'm not mistake)

 

Can I do anything if I prefer to Windows 7 64bit (not Windows 10 64 bit)? Every user writes that with WIN10 it will work better. What could be the problem?
