Keep getting ping spike only on nitro 5 AN515-51 laptop.How to solve?

Kemos

I am a Acer nitro 5 user from Johor Bahru,Malaysia. Since last week,I keep getting ping spike issues when I am playing my games like Team Fortress 2 and rainbow 6 siege. The ping usually stays at 10+ and reached 150 ping suddenly every 15 seconds or so.I have tried to switch every applications off already but the problem is still there.The router is not a problem as well as my brother that uses the same wireless connection pinged his local ip address,mac address and google.com but yet he get a constant low latency. I've used trusted security app to try and find any viruses in my computer but it shows no result. Is there anyway i can solve this issue? Thanks in advance.

Hi! I recommend you to forget the network connection. Click the Network icon on the lower right corner of your screen > Click Network settings > Click Wi-Fi > Under Manage known networks, click the name of your network. Then click Forget. The selected  wireless network profile is deleted. Later re-connect to the network with security key.Then try playing games and there should not be ping spike. Hope it works!
