ok guys, i would like to ask why am i getting disconnected from game so frequently ? at first, i thought it was server fault, but when im playing with my friend , i was disconnected but they werent(i mean alot of time). pc game and mobile game also like that, the ping keep spiking up and down and it is really frustrating not able to complete the game. the router and modem are provided by tm and i didnt change at all. is it the router problem or tm's problem ?

Hey guys , I would like to ask is it whether my router problem or modem problem ? The internet on the router which is tp link ac1200 has usually turn green to yellow for few minutes and then back to green. So whether it is the router's problem?
