I am setting up my new RT-AX88U. I flushed it with Merlin and happy overall but one thing annoys me tremendously.

Every time I make a change to any wireless setting (not just SSID or security) it takes between 3 and 7 min for the router wireless to come back alive (2G comes back somewhat quicker). Is it supposed to take that long? The LEDs for 5G and 2G stay lit most of the time though.

The log looks unremarkable:

I thought the "Roaming Assistant" was causing it so I disabled it for both 2G & 5G but it didn't make a difference, although the log still shows "roamast: ROAMING Start".

A reboot takes even longer.

I see a huge "time disparity", maybe NTP takes that long to initialize?

Is this timing normal?

If using 5.0 160MHz bandwidth, DFS scanning for RADAR at startup can delay the WLAN broadcast. Try 80MHz bandwidth on a non-DFS control channel to see the difference in startup time.

Thanks Ozark

I had to read up about the non-DFS channels. Indeed I had selected a DFS channel, not knowing what it was, solely based on how not busy the channel was in my neighborhood. As soon as I switched to a non-DFS channel, the WiFi started springing back to live within 15 sec or so. While not instant, it makes a huge difference when compared to 5 min.

Do I need to tag this thread with [CLOSED] or [SOLVED]? I am new here.

You're good. Thanks for doing the homework. You might also be able to glean some clues from my install notes.
