hap ac2 CPE mode not interworking with 5Ghz AX Mikrotik router?

RouterOS Wireless Networking

Hi,

I struggle with something that I thought works out of the box.

I do have hap ac2 with simple Wireless bridge setup (CPE) on 5Ghz Wifiwave2, connected as client to Audience 5Ghz AP (7.12.1 + Wifiwave2).
Doing exactly the same with hap ax3 (7.12.1 s well), Wifi connection is done but issues on the bridge, no DNS, no IP, no traffic etc.

This is hap ac2 configuration. (Audience and hap ax3 are exactly the same config, SW version etc 7.12.1).

/interface bridge
add name=bridge1
/interface wireless
set [ find default-name=wlan2 ] band=5ghz-a/n/ac channel-width=20/40mhz-Ce country=france disabled=no distance=indoors \
    frequency=auto mode=station-pseudobridge ssid=Mikrotik_SSID
/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa2-psk mode=dynamic-keys supplicant-identity=MikroTik
add authentication-types=wpa2-psk disable-pmkid=yes mode=dynamic-keys name=work supplicant-identity=MikroTik
/interface bridge port
add bridge=bridge1 interface=all
/ip neighbor discovery-settings
set discover-interface-list=!dynamic
/ip dhcp-client 
add interface=bridge1

Highly appreciate any advice. I tried with different station/station-bridge modes, but no success…

By the way doing CPE on the hap-ac2 2.4Ghz interface, it does work against Audience as well as with hap-ax3.

Config says you’re using legacy wireless driver on hAP ac2 … upgrade that device to 7.13beta, it allows you to use wifi-qcom-ac driver (essentially wifiwave2, but slimmed to fit on hAP ac2).

I know that using station-bridge mode between station and AP which don’t run same generation of wireless driver (legacy wireless v.s. wifiwave2/wifi) is not working. I’m not sure about station-pseudobridge, in theory it should be fine (in theory it works against 3rd party APs). But as they say: what is the difference between theory and practice? In theory none, in practice huge.

All of the above doesn’t explain why things work when using 2.4GHz interface but not when using 5GHz interface, but anyway …

MKX, you are a genius…

Who the hell would think that Wifi drivers are no more compatible among 7.12.1 products!!!

Solution is, you MUST use 7.13 on the “old” ac devices to connect as CPE/station bridge to 11ax 7.12.1 products.

Wonder if hapac2 will still connect now to the old audience with 7.12 running. probably not…

I think it will. Because incompatibility is between wireless and wave2/wifi drivers. And it’s (indirectly) documented in Replacing wireless package section of new wifi manual.

The 7.13 wifi driver is renamed (and enhanced) wifiwave2 driver from earlier v7, so it’s compatible with it (to extent of functions implemented in certain version of wave2). And ax devices were always required to run wifiwave2.
