High Ping Issue on Samsung S24 Ultra

[Ehsanatrn]

I have a Samsung S24 Ultra, and I'm experiencing a strange issue. On both 5 GHz and 2.4 GHz Wi-Fi bands, my router(Local Network) ping is around 20 milliseconds, while other devices show a ping of 5-6 milliseconds on the same network. I even performed a factory reset on my phone, but the issue persists. I wanted to ask other S24 Ultra users if they are facing the same problem. Galaxy S24 Ultra

I get the same  and it's causing me moonlight stutters,

My s24 ultra is in wifi 6 5ghz, and it's pinging also around 20/30 ms. Other devices ping is around 1 to 4 to local modem.

So I asked my brother he has a fold 6 with the came cpu as 24 ultra,  and he has the same problem, his fold 6 pings around 20/30 to his modem and other devices in his home have a ping from 1 to 4 to modem same like me,

Even wifi 2.4 ghz what uses wifi 6 protocol same problem 

So it's for sure a samsung problem with wifi 6 and up.

I am experiencing this issue as well. S24 Ultra. I was previously running the One UI 7 beta and it seems they fixed it at one point, but then I updated to the released One UI 7 and the issue appears to be back. Wifi latency is around 80-100ms. Other devices less than 10ms. 

I noticed that if I go to wifi settings > intelligent wifi > connectivity labs > wifi developer setting > wifi packet log debugging > and turn on air log capture. The latency drops to normal ranges of 5-10ms. 

I was able to transfer the packet capture to internal storage and view it with wireshark on a laptop. I saw that it was showing a bunch of malformed packets. However, my laptop doing the same capture isn't seeing the malformed packets.

I have S25U. This problem occurs because when you WiFi not use on full perfomance he turn power mode, you can see this, if you try speedtest and try ping test in same time, your ping was good like other device, after speedtest end ping again rise up. This problem. This problem has been around for a while now, and basically makes the gameplay horrible, with ping going from 5 to 50 in a matter of seconds. What's most surprising isn't that it hasn't been fixed, but that you can't change it in the settings. You can make this - intelligent wifi > connectivity labs > wifi developer setting > wifi packet log debugging. This fix ping, because after turn air capture log you wifi work on full performance all time, but because logs and other activities will still be written there, the battery will drain much faster
