hAP ax3 Station Mode - disconnected reason code 3

Tue May 02, 2023 10:12 am

Hi,

I connected a hAP ax3 to an Engenius AP in station mode (RouterOS 7.9 RC5).

Although the signal strenght should be good enough I keep getting disconnets like these regularly but at irregular intervals:
Code: Select all
88:DC:96:92:XX:XX@wifi1: connected on 5200/ax/eCee, signal -64
88:DC:96:92:XX:XX@wifi1: disconnected, reason code 3, signal -65
What is "code 3", and where to begin troubleshooting this?

Thanks in advance!

3 Deauthenticated because sending STA is leaving (or has left) IBSS or ESS

The client disconnected from the AP.

https://support.google.com/chrome/a/ans ... ason-codes

By experience ... possible suspects for disconnect reason code 3.
Client lost it's IP address (DHCP renewal?).
No more connection to internet.
Client is scanning for "station roaming"
Client exhausted retransmit limit. Too many retries.
Wifi interface needs to step down in the interface rate, but can't

Reason code 8 is gentle and quite normal. Reason code 3 is normally not a good sign.

Re: hAP ax3 Station Mode - disconnected reason code 3

I have this exact same issue between two ax3 devices and it was the same between a hap ac3(AP) and hap ax3(station).
I am trying to understand how to prevent this issue.
Both devices use wpa3 couple other basic configurations.

In my PC and mobile I just connect to the wifi and it stays on for hours while at the same time the AX3 disconnects from the AP.
What might cause this, is there any configuration that can help to resolve this issue? (less then 10 Meters between the units in open room).
both the AP and the STATION has static ip address in their own SSID dedicated for their connection.
All the other clients are connected to the HAP AC3.

Why is it leaving?

Re: hAP ax3 Station Mode - disconnected reason code 3

Disconection hap ax2/ax3 in station mode with reason code 3 or 8 takes place when AP works in 5470-5725 MHz,
It happens with hap ax2/ax3 in working with any AP wifi 6 from any vendors.
When AP changes frequency to 5150-5350 MHz ( with the same configuration ) hap ax2/ax3 in station mode became to work fine.
So, it is software mistake, that Mikrotik should fix.

5470MHz is an odd place in the allowed spectrum

Check your Country setting. If no country is set the default country used has become Latvia (not US anymore!) since recent ROS 7.13.x versions.
Code: Select all
[admin@hAPax2] /interface/wifi/radio> reg-info                                                                    
country: Latvia
number: 0
  ranges: 2402-2482/20
          5170-5250/23/indoor
          5250-5330/23/indoor/dfs
          5490-5730/30/dfs
          5735-5875/14

And for Israel ....
add band=5ghz-ax disabled=no frequency=5745
This is also the SRD (short range devices) power level at only 14dBm EIRP level. This is LOW TX POWER !
Code: Select all
[admin@hAPax2] /interface/wifi/radio> reg-info 
country: Israel
number: 0
  ranges: 2402-2482/20
          5170-5250/23/indoor
          5250-5330/23/indoor/dfs
          5490-5730/30/indoor/dfs
          5735-5855/14/indoor
