These worked for me:
replacing the cable that goes from your modem to wall socket,
calling isp guys to reduce noise and stuff
replacing the modem
and reset the modem, works every time idk why.. each time i rest, my ping changes.. most of the time it increases, but i can get 300 ping once, reset modem then get 200 , it happened lol
PING-PONG:D.... this program sucks.... i can just run a few terminal commands and do this.. but then again. i dont have a shitty computer like he does so i dont have to do it.
