Lag badly while gaming using Wifi
im playing mobile legend player using my new iphone11.
the problem is when using wifi (while turn off other non essential background apps) the game keep lagging & ping not stable.
1) i set the graphic to lowest everything.
2) turn on data & wifi together
3) follow suggestion from youtube etc
4) update latest ios
5) end up reset to factory
but the problem still persist.
lastly i turn off wifi play the game using mobile data only, set graphic to ultra & THERE IS NO LAG ISSUE AT ALL. Please help.
