Solved Enable/Disable guest network on schedule (crontab)

[mvadu]

I have few Tasmota IOT devices running on ESP8266 chips. They have some compatibility problem with Asus AiMesh they keep going in loop trying to connect and failing to connect (no error in Asus side, but device thinks it couldn't find the access point.

wlceventd_proc_event(491): wl0.2: Deauth_ind 98:F4:AB:EA:CA:6F, status: 0, reason: Deauthenticated because sending station is leaving (or has left) IBSS or ESS (3), rssi:0
wlceventd_proc_event(527): wl0.2: Auth 98:F4:AB:EA:BB:AA, status: Successful (0), rssi:0

What I have noticed is if I stop and start the access point, they connect just fine. So I moved them to a guest network so its very easy for me to disable/enable the guest network. Now I want to try doing that every day at a specific time (proactively instead of doing it reactively after seeing the device failures). SO I started looking if there a command I can run in the shell (so it can be added to crontab) which is equivalent of GuestNetwork->Remove/Enable?

Looking at github code, its calling a en_dis_guest_unit (https://github.com/RMerl/asuswrt-me...release/src/router/www/Guest_network.asp#L903). Which is updating some qos based on the guest network number (e.g. second guest network is wl0.2). But my reverse engineering skills aren't deep enough to figure how dis_qos_enable function is actually dealing with interfaces.

Is it ultimately as simple as toggling that interface?

merlin@RT-AC86U:/tmp/home/root# ifconfig | grep wl
wl0.1     Link encap:Ethernet  HWaddr 0C:9D:92:AA:DD:B1
wl0.2     Link encap:Ethernet  HWaddr 0C:9D:92:AA:DD:B2
merlin@RT-AC86U:/tmp/home/root# ifconfig wl0.2 down
merlin@RT-AC86U:/tmp/home/root# ifconfig | grep wl
wl0.1     Link encap:Ethernet  HWaddr 0C:9D:92:AA:DD:B1
merlin@RT-AC86U:/tmp/home/root# ifconfig wl0.2 up
merlin@RT-AC86U:/tmp/home/root# ifconfig | grep wl
wl0.1     Link encap:Ethernet  HWaddr 0C:9D:92:AA:DD:B1
wl0.2     Link encap:Ethernet  HWaddr 0C:9D:92:AA:DD:B2

The actual command linked there is no longer available

The commands to stop/start both the 2.4 and 5G Guest wireless instance #1 are given here by RMerlin:

@RMerlin sir, any luck you can provide the command we can run on the shell which will enable/disable given guest SSID?

also tagging @L&LD as well

Use the commands shown towards the end of the thread you were linked to earlier.

ah.. I should have just kept keep scrolling. I went into the links and got lost.. Thank you that pointer @ColinTaylor
