Product: HP Envy X360 Convertible 15-cn0xxx

Operating System: Microsoft Windows 10 (64-Bit)

My laptop keeps disconnecting and connecting to the WiFi. whenever i stream the video on YouTube,Twitch  or play online games like League of Legends (on lowest graphic mode) it keep on disconnecting + huge Ping (ms).  When it is connected, it is sometimes strong then few minutes later weaker then disconnects. I am sure the problem is with the laptop. i just bought this laptop 3 months back. 
What should I do ?
My device manager shows under network adapters:

- Kaspersky Security Data (E) Adapter
- Realtek RTL8822BE 802.11ac PCle Adapter
- WAN Miniport (IKEv2)
- WAN Miniport (IP)
- WAN Miniport (IPv6)

Hi

Therefore a faulty adapter?

Copy, Paste and Save in Notepad, as LBB.bat (not a .TXT) and double click to run.
Preferably run as an Administrator
OR copy and use the individual command lines as needed.
Post anything non-personal, but relevant please.

@ECHO OFF

netsh lan show interfaces
netsh wlan show drivers
netsh wlan show interfaces
