Hi everybody,

Randomly, every days, my 2.4Ghz clients no longer have internet access, when it tries to connect to the wifi network, it disappears and then reappears in my client list but does not stay connected.
I have been looking for a solution on the forum for a long time (disabled Airtime, enabled Bluetooth Coexistence ...) but I cannot find what could cause my problem. Can you help me ?
Firmware : Merlin 384.16
Asus RT-AX56U

No problem with 5ghz.

Hi,
I´m not an expert, but I would try to disable the option to selection channel 12 & 13. Some devices may not be too fond of these I believe. Also - maybe try a fixed channel (1-11).
 

L&LD

Part of the Furniture
Do not use Auto Control Channels for either band (eventually, you'll have issues on both). Use 1, 6 or 11 and 20MHz bandwidth for the 2.4GHz band. Use non-DFS channels for the 5GHz band with 20/40/80 MHz bandwidth.

Disable Universal Beamforming. Disable Airtime fairness.

I would also suggest an 8 alphanumeric character SSID with no spaces, punctuation, special characters, or smiley faces. The password the same except for 16 characters long too.

I don't know when the problem appears but I've always activate time settings to stop the 2 wifi networks at night. Perhaps the problem appears at the time of reactivation. I am with a second router for Aimesh.

As you can see I have changed the parameters as recommended by @L&LD

Seems like the 2.4 GHz radio flats out dies. Try a complete power reset (unplug the power for 5-10 seconds with the router still turned on, then plug it back in). If it still fails, contact Asus or the reseller for a replacement.

I did a factory reset but the problem persists. I sent a ticket to Asus support... Awaiting.
In all case, thanks for your help.

But did you try an electrical reset as suggested, not just resetting your settings?

Do you think I can try a most stable firmware ?
It's not a firmware issue. Your log indicates that the radio flats out dies/crashes.

I have the same problem with by brand new AC3100. If I factory reset it back to the latest stock it works fine. It is happening wit .17 and .16 but that is far back as I have tested. I have done countless factory resets and restores, unplugged the power for a few minutes, etc. It seems like the radio is working because the site survey is showing other networks on 2.4ghz.

If I reboot the router I can see clients on 2.4ghz for a while, but at some point they disconnect.

You mean you no longer have the problem with the Asus firmware 384.8253 ?

PS: I noticed that the problem only occurs at night when "wireless scheduler" is activated so the wifi network is switched off...

I can still go back to the stock firmware and everything works fine, but I really want to use the extra features in Merlin. I use the Parental Controls and time scheduling, but not on the devices that are using 2.4ghz. Here is what has happened so far this morning.

8am - Unplugged router for a minute and powered it back up.
Looked at the current clients and some are on 2.4ghz, most are on 5ghz.
Sometime around 10:30am-11am - no clients on 2.4 and a 2.4 only client can not see any networks.
Around 11:15 - the 2.4 only client can see network again.

I am currently setup to use Smart Connect, because if a 5ghz capable device connects at 2.4ghz it will reconnect at 5ghz when 2.4 fails.

I have an ax58u that is exhibiting the same issue as @screamjojo . When new, the 2.4 worked but i immediately went to Merlin .17. I went back to stock earlier and noticed that when i booted after the flash to stock, the 2.4 asus network name wasnt listing. I am seeing the same wl0 crash in the logs. It is an eBay refrub and I will contact the reseller for a replacment.

@screamjojo Did you solve your problem?

Hi,
When I go back to stock, problem always here. But I've don't try a hard reset after I go back to stock firmware.
My solution : Activate Smart Connect. But with all this problems (2,4ghz crash, QOS bandwitch limiter not working good ...) I think this router is not stable, I will not keep it.
Good luck, hope team Merlin or Asus will fix this issu...

@screamjojo, if you're not testing with a full reset after flopping back and forth from stock to RMerlin firmware, no wonder the router isn't stable for you.

This may (or may not) be an issue for either Asus or RMerlin to fix. :)

I'm having the same issues as mentioned above by @screamjojo and FYI, it's been straight out of the box and with stock firmware since day 1 having this issue.
 

L&LD

Part of the Furniture
@Waffleboi, how many firmware versions have you flashed since 'day 1'?

Flashing between different flavors of firmware isn't the only reason to do a full reset if the situation warrants it.
