Hi guys, i been getting constant spike every 15 secs and nothing I do could fix. Ping is always 33-66ms then spikes up to 200-300ms for a while then back to normal.

Will VPN fix it ?

VPN won't fix it. Might even make it worse. Contact your ISP for help. What ISP you using? Some ISP's like Maxis Fibre have problems after 8PM. I'm using them. Though, I get <90ms.

understand what is vpn 1st. your net prob, nomatter what you use, still will prob.

using vpn for online game will only increase delay

im using streamyx 4mb, only started having this problem recently.

before this never suffered spikes or packet losses

as usual, check your phone got noisy sound or not, or just simply call tm and scold them. i do that everytime my net got lag or spike and im sure its not from my side. ask them put you top prio

you might want to try WTFast.

They do provide one-month trial

downgrade to streamyx 384 kbps and enjoy 40 ms ping

I had that problem once. But next day it resolved it self.
