Virtual SSID ip problem.

Fri Aug 14, 2020 5:33 pm

Hi. I have hard time setting up Virtual SSID for Mikrotik RB4011iGS+5HacQ2HnD (arm) for Atheros chip. It does not just work and devices can't get IP.

I have set up:
wlan1 (Wireless QCA9984) ==> SSID: AE (as in end device can choose whichever radio it prefers)
--> wlan5 virtual (wlan1 master) ==> SSID: AE5 (as in for dedicated 5GHz radio)
wlan2 (Wireless Atheros AR9300) ==> SSID: AE (as in end device can choose whichever radio it prefers)
--> wlan22 virtual (wlan2 master) ==> SSID: AE2 (as in for dedicated 2.4GHz radio)

First three (wlan1; wlan5; wlan2) work perfectly. Whereas the last one, virtual interface wlan22 created with Master interface wlan2, just does not work as expected.It is visible to end devices; they can connect to it (PSK seems to work); And it fails at getting IP. Android device gives "IP Configuration Error". Same android device does not support 5GHz wifi at all and works therefor perfectly with wlan2 (using SSID AE). Gets IP and works. Have tried to disabling wlan22, enabling, deleting and recreating. Nothing seems to help.

RouterOS 6.47.0 first noticed this and now upgraded to 6.47.1 and still the same problem. Is this like a known issue/bug and is there some workaround for this?

Config seems also identical enough...

Did you make sure that you added the new wlan interfaces into the bridge where the DHCP server is ?
