Not _all_ the octopuses. I look after some here...

Unifi seems a bit odd, and I can't explain its behaviour.
I've got four VLANs to the AP, let's say 7, 8, 9 and 10.
VLAN 7 is default, is defined in Unifi by network address range only
(the VLAN number isn't in the Unifi config), and dynamic assignment on
SSID1 works fine.
VLAN 8 is the static VLAN on SSID2 (no dynamic assignment). There is no
network covering it in the Unifi config. SSID2 works fine, but
dynamically assigning VLAN 8 on SSID1 doesn't.
VLAN 9 is not defined in Unifi anywhere. Dynamic assignment works fine.
VLAN 10 is defined in Unifi as a Network. Dynamic assignment doesn't
AP has trunk - VLAN 7,8,9 are tagged, VLAN 10 is untagged (the AP
management is on 10).
(There's actually also another VLAN which is at another site on another
AP, and that's not defined anywhere either, but works fine dynamically
So that looks like the network must *not* be known to Unifi for it to
work. Except in my case for VLAN 8. But I have a feeling I read
somewhere that statically assigned VLANs for an SSID can't be
dynamically assigned for another SSID (grrr) which might explain that
(I just added network 8 to the Unifi config and it still doesn't work
when dynamically assigned to a user. I also added network 9, and that
still *does* work. <sigh>)
I don't have a Unifi "security gateway", this is all normal switches
My *guess* is that the "networks" list is irrelevant for dynamic
assignment: the untagged VLAN doesn't work, any static VLAN for another
SSID doesn't work, but all other VLANs do.
All rather weird. One thing is certain, though: FreeRADIUS is working
