Spiking ping

Hi guys,

so ever since the update, my ping has been going crazy. Its spiking 20-80 or even 20-200 at times. I tried everything possible before posting this thread so i wouldnt waste anyones time.
I tried redownloading Gunz, turning antivirus and firewall off as well as adding it to the exceptions in both. I turned Windows Defender off. I checked my internet connection. Nothing helped. Its getting a bt frustrating because its not as enjoyable with everybody spiking and teleporting, especialy in glad.
Im the only one using my net aswell so..

Any advice would be appreciated :l Thanks
