Issues creating WI-FI network

I'm trying to create a WI-FI network with the pISO connected to a wi-fi enabled raspberry but the pISO gets stuck.

I added the following configuration to the piso.config:

[wifi.ap]
ssid="echopiso"
password="******"

i can browse to the wi-fi menu and choose Activate AP but the pISO gets stuck with the "Creating network" message.

the pISO has 2 disks configured and mounted.
