BUG: WDS over 2.4Ghz works, but over 5Ghz does NOT.

RouterOS General

Hello,

I have there 3 devices:

  1. wAP ac
  2. hAP ac #1
  3. hAP ac #2

I can easily make a WDS link between any two in all combinations, except one:

  • hAP ac <— 2.4Ghz —> hAP ac
    works OK
  • hAP ac <— 5Ghz —> hAP ac
    works OK
  • hAP ac <— 2.4Ghz —> wAP ac
    works OK
  • hAP ac <— 5Ghz —> wAP ac
    does NOT connect to each other. … WHY?

I have checked wireless settings many times, they are the same.
I use dynamic-mesh mode, because no special configuration is needed in that case.
I can see the networks in Scan dialog, the devices are a few meters from each other, so the issue should not be signal related.


/interface bridge
add name=bridge1

/interface wireless
set [ find default-name=wlan1 ] band=2ghz-b/g/n country="czech republic" disabled=no frequency=2462 mode=ap-bridge radio-name=AP4 ssid=MYSSID
wds-default-bridge=bridge1 wds-mode=dynamic-mesh wireless-protocol=802.11 wps-mode=disabled
set [ find default-name=wlan2 ] band=5ghz-onlyac channel-width=20/40mhz-Ce country="czech republic" disabled=no mode=ap-bridge
radio-name=AP4 ssid=MYSSID wds-default-bridge=bridge1 wds-mode=dynamic-mesh wireless-protocol=802.11

/interface wireless security-profiles
set [ find default=yes ] authentication-types=wpa-psk,wpa2-psk eap-methods="" mode=dynamic-keys supplicant-identity=MikroTik
wpa-pre-shared-key=PASSWORD wpa2-pre-shared-key=PASSWORD

Am I missing something?

Any ideas?

I bought another wAP ac and now I believe this is a bug:



  • hAP ac <— 2.4Ghz —> hAP ac
    works OK
  • wAP ac <— 2.4Ghz —> wAP ac
    works OK
  • hAP ac <— 2.4Ghz —> wAP ac
    works OK
  • hAP ac <— 5Ghz —> hAP ac
    works OK
  • wAP ac <— 5Ghz —> wAP ac
    works OK
  • hAP ac <— 5Ghz —> wAP ac
    does NOT connect to each other. … WHY?

both wAP ac and hAP ac have the same WiFi cards (Atheros AR9300 and Atheros AR9888), so it should work.

@normis Is this a bug?
