GT-BE98 Pro: 40,000+ ms ping using Wi-Fi 7 despite 4 Gbps up & down

[Ceejus]

I'm at my wits end here and have no idea what else to try. When I enable Wi-Fi 7 Mode under Connectivity Labs (enabled by default) on my S24 Ultra, I'm able to get 4 Gbps/4 Gbps speeds consistently, but connections take forever. I don't get this result when I turn Wi-Fi 7 Mode off and use Wi-Fi 6E. This happens no matter how close or far away I am from the router; I could have an RSSI of -37 and still get the same 40,000+ ms ping. Oddly, the issue doesn't occur for the first couple of minutes I'm connected. This is the case no matter what band MLO is using. I did notice the issue would occur with MLO off, more frequently on the 6 GHz band but sometimes also on the 5 GHz band as well.

Nothing I'm seeing in the connection indicates why these pings are so insanely high. I get the same result when using 160 MHz-wide channels or 320 MHz-wide channels. I am using PSC channels; I've tried both Auto and setting the channels manually. Under Professional, I have Wi-Fi 7 Mode enabled along with DL/UL OFDMA and DL/UL MU-MIMO.

Is anyone else experiencing this?

It's interesting that you get 4gbps up/down on your S24 Ultra. I have 5gbps up/down Fios and I get only 2.4gbps up/down from my S24 Ultra. On the other hand, the ping delay of > 30sec is something I have never seen even with slow network. I typically get from 5 to 7 ms ping delays using Ookla speed test. What's your ping times from a wired port connection? is that normal < 10ms? It's also worth checking the CPU memory use and load/activity to see any process holding up the CPU.
Enable ssh and log on to the router using ssh and check( eg: ssh admin@asusrouter.com -p 22)

Pings from a wired port are 5 - 7 ms like yours. The speeds and pings are fast and consistent on everything except for Wi-Fi 7. Something about Wi-Fi 7 specifically is causing an insanely high ping and slow connections despite having around 4 Gbps up/down. I haven't seen anyone else report this issue.

What are your Wi-Fi 7 settings?

Are you sure? 40.000ms is 40s. It will time out before that. Dead connection, basically.

Things will eventually load after about 40 seconds. When I go into Connectivity Labs > Wi-Fi Developer Options > Wi-Fi and Network Diagnosis > Network Diagnosis > Run Connectivity Check on the S24, my HTTP and HTTPS probes are consistently around 10,000+ and 40,000+ ms respectively. Certain apps that load instantly on all other Wi-Fi versions and wired connections take over 40 seconds to load on Wi-Fi 7.

I've tried restarting the Wi-Fi subsystem and wiping the cache partition on the S24. Same result every time. Nothing I'm seeing in the router's logs seems to indicate what's driving this. CPU usage is fine - around 10% average per core.

Are you referring to the PROBE_HTTP & PROBE_HTTPS numbers? Yes I do see them in the range of 40s. However I'm not sure what this number really means.

I only get those numbers when I'm experiencing the Wi-Fi 7 issue. Otherwise, those HTTP and HTTPS probes are under 1,000 ms.

This whole situation is bizarre.
