Hello,

I have a Asus RT-AC56U, with AsusWRT-Merlin firmware version 378.53.
This router has the eth1/wl0 (2.4 GHz) and eth1/wl1 (5 GHz).

Is possible to [create/edit/manage/start/stop/remove] a Wifi interface via command line/shell without reboot?

The default configuration uses LAN 1-4, eth0 and eth1 as VLAN1. If I enable a Guest Network via Web, lets say wl0.1, it will be added on the VLAN1.

Using "robocfg", I removed the LAN2 (switch port 1) from VLAN1 and added to VLAN4, then used "vconfig" to create the VLAN4 interface and finally "brctl" to create the br4 (this bridge will be used to later).
It is working well, the br4 have a IP address, my computer (connected to LAN2) can ping the router and vice-versa.


Now I am trying to remove the wl0.1 from VLAN1 and add to VLAN4, using a bridge interface. Example:
Code: 
brctl delif br0 wl0.1
brctl addif br4 wl0.1

But when I do that, the wl0.1 just stops (the SSID is broadcasting, but if a client try to connect, it will not connect - time out)

I tried run "wl down"/"wl up", but without success.
The wired part is working (via LAN2), I can ping the router and the router can ping my computer using VLAN4 (access via ssh as well).

Do I need to restart any service? (without reboot)

Some additional information (if needed):
