AX3200 (AX6S): 5Ghz AP activated but devices can't see it

Evv1L · April 25, 2025, 3:15am

Hello OpenWrt Forum! I need help with very strange 5G wireless bug on my Xiaomi AX6S

Luci says that 5Ghz AP is activated and channel is set, but none of the multiple devices can see it. Also I can see neighbor's 5G networks just fine - just mine is missing. Wireless Scan also works fine - router can see other's 5G access points.

Fixes I tried:

Downgrading OpenWrt to lower versions: 23.05.05 and 24.10;
Different country codes / modes (N,AC,AX);
Using non-DFS channels (36-48);
Completely removing WiFi AP's in Luci and creating them from scratch;
Fix from AX6S device support topic.
And none of this worked

Also I don't see any error messages related to 5Ghz networking in logread, at least I didn't notice them.

My WiFi card clearly has support for 5Ghz networks. I use Intel AX210

(I disabled 2.5Ghz on purpose and I have no issues with 2.5 at all)

Device logs are down below:

}

Also my router has older variant of bootloader if that helps.

Set another region to check the work.
The KZ region has many restrictions, as Google claims, up to the ban on connecting to unpassworded networks. Intel honors all the rules and this is not a very good card, which should be considered as truly correct.
To the point that Intel reads the region codes of neighboring Wi-Fi networks and geodata of devices and blocks “incorrect” connections at the driver level.

Set another region to check the work

I tried RU, US and PA regions. Same result. With WPA2\WPA3 password as well.

Have you tried connecting another client, not Intel?
You also have the channel set to "auto", although it shows that 36 is selected, try setting it manually, for example 42.

Evv1L · April 25, 2025, 10:55am

Yes I tried. Android devices also can't see my 5ghz network but can see neighbors'.

Does rolling back to stock firmware solve the problem?

acn · April 25, 2025, 11:38am

Try some EU region.
Have the same router as dumb AP.
On DFS channel 100 (like you had according to the log) some clients do not see the AP for a while. For example, on android phone, if I turn of wlan and turn it back on, the phone sees all APs except AX6S
After 1-2 minutes phone finds the AP and connects fine.
Happens only with DFS channels, probably some client thing. It's like it does not scan DFS channels for a while.

In my country, any supported 5 GHz device connects to this router model, whether it's stock, 22, 23, 24, or whatever else was available for this router.
But jumping from 24 to 23 and from 24 to 23 could damage the firmware area responsible for Wi-Fi settings, and then it's really bad. You need to restore from a backup, if you have one.

Please refrain from suggesting illegal tests (i.e., switching radio regions)

Is this device running OpenWrt, or OEM firmware?
What version of OpenWrt did you originally run?
Are you keeping settings or resetting to defaults?

Lexeyko · April 25, 2025, 7:29pm

This is a former USSR country, not only is it illegal to do anything with Wi-Fi, it is even illegal to be born and live there, so this is a completely harmless experiment))).

Upgrading from 23.05.5 to 24.10 using this guide on device wiki page was the last thing I did before 5Ghz network stopped working. I didn't do OpenWrt's settings reset before updating because the settings are lost anyway.

I got OEM 1.0.83 firmware on purchase, global RB01 variant.

Also I flashed OEM 1.0.71 image yesterday via TFTP (and facinstall method as well) and 5G network is still not there for some reason. Smart Connection feature that combines 2.5Ghz and 5Ghz under one SSID is turned off.

Now I'm wondering is this hardware issue or some kind of firmware bug?

Here are some errors I got running OEM 1.0.71 firmware:
