Mikrotik hAP ax s WiFi station

When connecting from Mikrotik to any other wifi network over 5ghz it works fine, now when trying the same over 2.4ghz DHCP client cannot get IP address it. In DHCP client tab it shows scanning and never finds an IP. Now I have tried connecting to dozens AP’s always acting the same, but if I try same AP with 5ghz antenna it works perfectly. Can anyone advise what I’m missing, is it a bug, will be it fixed?

In Wifi / Register tab it shows that connection is present Rx/Tx are moving back and fort.

I have tried station, station-brigde, station-pseudo-bridge modes - nothing.

On which interface is the DHCP client configured for 2.4 GHz WiFi?

Do you want to use hAP as travel router? use 2.4 GHz radio as station to connect to the AP wifi network?

You cannot connect to an arbitrary other AP in bridge mode, that is just a limitation of the standard.

When you have an “ax” MikroTik device it can use bridge mode with other ax type devices, and with ac type devices that are running the new wifi-qcom-ac driver, but not with older ones.

When you still want to make such a setup you need to take the wifi interface out of the bridge, put the DHCP client on the wlan1, configure a DHCP server and IP address on the bridge, and thus use routing instead of bridging. Then it will work.

Not quite a travel router, but using it as upstream router to other wifi networks for redundancy.

@pe1chl is quite right it has something to do with compatibility between routers as I'm trying to connect to N standard router.

Managed to get it working via station-pseudobridge after resetting and completely reconfiguring it from scratch, other modes does not work. Strangely that it shows connected anyway, but does not issue IP address..

That isn’t strange when you completely understand how station-pseudobridge and DHCP work!

You cannot (reliably) use DHCP over station-pseudobridge.

Configure as a home router.

Remove the 2.4 interface from the Bridge

Add DHCP-Client to 2.4 radio.

Add 2.4 interface to WAN using interface lists.

Then which mode would work reliably when connecting from AX to N protocol?

Usually in devices set to station-pseudobridge there are issues if rstp Is enabled on the bridge (and this Is the default setting) and It Is advised to turn It off (protocol-mode=none).

I am connecting my AX3 to office network using Cisco AP via 2.4GHz wireless. Just using usual travel router configuration

I use station mode to connect. Following the ways to share the wifi to the other devices connected to AX3

wifi2 is the 2.4 G radio
wifi 1 is 5 G radio managed by remote Capsman
wifi 2 is slave of wifi2 for mobile devices to connect
