[Cefix]

Hallo,
after some days of looking through the FAQ's and the forum I, unfortunately, haven't figured out yet to set up this kind of configuration:

I try to set up a Guest WiFi in a separate Subnet and followed this guide here
the setup now actually works.

After testing for a while I decided to give my guest not only the 2.4 but also 5.0 Ghz to connect.
to do this I wanted to assign wl0.1 and wl1.1 to br1 with the same settings I had before for wl0.1.
Unfortunatelly as soon as I do so, I can not even connect anymore to the Wifi

my current wl0.1 setup (that works)

Network Configuration wl0.1

Unbridged
MTU 1500
Multicast forwarding - Disable
Masquerade / NAT - Enable
Net Isolation - Enable
Forced DNS Redirection - Enable
Optional DNS Target 202.96.209.113
IP Address - 192.168.5.1
Subnet Mask 255.255.255.0

Multiple DHCP Server

Interface wl0.1: IP 192.168.5.1/255.255.255.0
DHCP 0 / wl0.1 / On / Start 100 / Max 50 / Leasetime 1440

as soon as i copy this setup over to br1 im not able anymore to connect to the VAP i've created
Maybe one of you can point me in the right direction.
Thanks
