Packet loss is normal as protocols and such replace missing packets. I've programmed routers years ago and once in a while you encounter someone new that thinks UDP would be free of lost packets. Sorry, that's normal.
You can improve gaming results by getting wired. WiFi is great but gamers often complain.
If you feel it's the gear, talk to the makets about firmware updates and settings.
Ive had an apple router for a while, but recently I began to experience unusually high ping when I play videos games. It would go up to around 120ping and sometime even 400 ping in extreme cases. I also did multiple packet loss tests, i would get about 4% packet loss every two tests. I have tried restarting the router and modem. Neither worked. Please help
