hAP ax^3 2.4G wifi doesn't work

Hello, after factory reset of my router I can’t make 2.4G wifi work…
Router is hAP ax^3
OS version is 7.8

Config:

[admin@MikroTik] /interface/wifiwave2> print detail
Flags: M - master; D - dynamic; B - bound; X - disabled, I - inactive, R - running 
 0 M BR default-name="wifi1" name="wifi1" mac-address=78:9A:18:3A:8F:C5 arp-timeout=auto radio-mac=78:9A:18:3A:8F:C5 
        configuration.mode=ap .ssid="5G" 
        security.authentication-types=wpa2-psk,wpa3-psk .passphrase="xxxxxx" 
        channel.band=5ghz-ax .width=20/40/80mhz .skip-dfs-channels=10min-cac 

 1 M B  default-name="wifi2" name="wifi2" mac-address=78:9A:18:3A:8F:C6 arp-timeout=auto radio-mac=78:9A:18:3A:8F:C6 
        configuration.mode=ap .ssid="2G" 
        security.authentication-types=wpa2-psk,wpa3-psk .passphrase="xxxxxx" .management-protection=allowed 
        .management-encryption=cmac .wps=disable 
        channel.frequency=2300-7000 .band=2ghz-n .width=20mhz .skip-dfs-channels=disabled

From router perspective it looks like everything is ok, but I don’t see network, also can’t connect via winbox using 2g mac address. 5g works perfectly.
I tried: changing channel width, different bandd, playing with DFS, tx power, countries, different SSID names.
I don’t have anything connected to router except WAN internet cable.

I had this issue earlier at some point earlier, didn’t have time to find a solution and at some point it started working itself… Now facing same issue. I’m pretty newbie in MT stuff, so assume it can be something obvious.

Thanks!

Set frequency to fixed value and try again. Right now you set frequency from 2300 to 7000 MHz

I did. Tried again just now. Tried 2462, 2473 and 2412 with no luck…

Also I updated OS version to 7.12 (with no results regarding my issue)

Are there any messages in logs regarding wireless ?

Nothing except logs about changing settings.

And router is having a same symptoms with a default configuration ?

Yes. This actually happened after factory reset.

Please post config of wifi part.

perhaps start with upgrading to latest version …

Same issue here except with the hAP ax^2. Version 7.16 (stable). Factory Software 7.5.

Pretty out of the box config - one Ethernet port connects to my internet box, one connected to my computer. Enabled WiFi and named it. All good, with various WiFi devices.

Today I wanted to force some devices on to 2.4GHz for development purposes and so disabled wifi1, which is listed as the 5GHz interface. The SSID disappeared entirely from scans on all devices! I realised that I’ve probably never connected on 2.4GHz (it never showed any traffic).

So I tried giving wifi1 and wifi2 separate SSIDs, trying every combination of bands, rebooting, every combination of enabled/disabled, every combination of “Skip DFS Channels”. No luck.

I noticed:

  • the 2.4GHz SSID never appeared.
  • the 5GHz SSID often also didn’t appear, depending on the band I picked, or indeed if I changed it to United States instead of Australia.
  • all devices (an iPhone, and Android tablet, a Mac desktop) saw the same SSIDs.

Are others able to see the 2.4GHz AP?

I would try netinstall to 7.16, applying default configuration and not touching anything.

Also you could enable logging for wireless:

system logging add topic=wireless action=memory

https://www.usb.org/sites/default/files/327216.pdf

I’m not the OP, but that’s what I’ve done - fresh out of the box, and then just change the SSID so the 2GHz one is different. No 2GHz SSID can be seen by any client.

Are you saying that’s unexpected? So maybe this is a warranty issue?? No 2GHz WiFi seems pretty fundamental, but there’s half a dozen related reports in this forum over the course of many years, so maybe it’s a known issue? Although they are mostly about connection instability, rather than the SSID not appearing at all.

Also you could enable logging for wireless:

Good call. I did this though and it didn’t seem to make any difference. Connection/disconnection events were already in the log, and the running of the command appears in the log. But after that, nothing appears when the 2GHz radio is configured/enabled/disabled other than the config/enable/disable command.

There is always a possibility of a faulty hardware, but also I think that’s better for OP to go through all possible solutions that maybe solve this problem.

If this doesn’t solve the problem then he can take the device to his distributor and describe what the problem is and what he tried to do to fix it.

I have the same issue (there is RED alert: “device does not support management protection”) but with Chateau AX with 7.16. I am using CAPSMAN, have also 4x cAP AX but they have previous package 7.15.3 and there is no problem - they are working OK.
It only impacts on 2Ghz on local interface 2Ghz (5Ghz is also OK).
It looks like there is some problem with 7.16, am I right?
It was set many month ago with no changing - it appears last days after upgrading to 7.16

Any one else has also such a problem?

no i was running 7.16 no issues with capsman and 4 capax so it is some thing that your config isnt right
do you have the correct wifi drivers installed
do you have a export of the config so we can have a look pls

I thinks so - it was everything all right till last updgrade (attachement)

Ok so first off
why running 2 different wifi ssid for ax and n on the 2.4G
and why runing 2 different for the 5G
why not just run the ax on both with bigger channels to choose from like first of let it be auto picking
have you looked in the area of the wifi to see if any channels free to use from interference yes i no 2.4 is full but need to find a clear area to use
same goes for 5G have a look at my picture i uploaded as devices will pick what there wont to run
i only set up the information in the config tab next to wifi i had all the other ones setup and was having issues and buggy wifi so i removed all the Channel,security tab and ONLY do it in the CONFIGURATION TAB so caps get the same
next i see that your running caertifacates on the caps
i was and found that when the router rebooted the certs didnt work after and i had to muck around with them again as the ap not worked so i removeed the certs all togther
can u show me the wifi like this im no expert but i will try to help you
im running hapax3 and 2 capax and a hapax2 in capsman and all work pretty well

Hi Coughy,

Thanks for your reply…

But I don’t have different SSIDs - it’s only one on all interfaces - there are only different names on each of interface/cAP.
I’ve tried not using TABs but there is no difference.
I even turned off all cAPs - and even 5Ghz interface, just let only one 2,4Ghz be ON - it is still error on this interface.
With or without CAPSMAN also.
Also removed certs - no progress…

I found in the TESTING version 7.17 BETA there is 802.11h disabled for 2,4Ghz - maybe this is the issue?

What is the point of running WPA2 and WPA3 on same network at same time? It doesn’t matter that there are some clients connected over WPA3 when there is WPA2 still available. Security of your network is always the lowest one = WPA2.

Now you know that your WPA3 is pointless so and you can disable management protection. Solved…
