So recently my family got a new ASUS router even though our old netgear router was working perfectly fine. I also use an extender as it does not usually reach my room. Ever since we installed the new router, my pc internet has been absolutely horrible. I cannot enjoy any sort of game without my ping going from 40 to 200+ every single second. I would even use speedtest.net and speedtestIO and they both would say I have 2 ping with like 50 upload and download speeds. I have no idea how to fix this problem, I tried looking it up and many just say it is a high latency problem but I have no knowledge of this kind of stuff so I am just stuck.
