Meteobridge Nano SD still broadcasting setup ssid

Post by staze » Wed Jan 30, 2019 4:16 am

Hi All,

Anyone else seeing their Nano still broadcasting the setup network? It's on my network, and is working... but for whatever reason I still see the meteobridge-B8D8xxxxxxxx network in my wireless networks (which, seems wrong).

Seems like that is just cluttering up my wireless channel availability in my area. Can I turn it off?

Thanks!

I'm afraid you cannot. i had discussed this before:

viewtopic.php?f=56&t=13370

since i have two APs in my house with 20mhz broadcast and the NANO at 40Mhz it bleeds into my network channels.

I'm sure if some form of failsafe could be created that if you reset your device then wifi comes back on. otherwise this broadcast is just eating more cpu processes for nothing, and interfering with my wifi channels.

bummer. I've added my voice to the other channel. Hopefully we'll get the feature added to turn it off.

Unless OpenWRT does this in some manner I cant see it happening soon.

I mean, looking at Advanced under Network (where it goes to OpenWRT interface), I see two possible options.

Comment out the cron task for the test5m (not sure if that will work), or possibly edit the lan interface since it's the one attached to the meteobridge ssid...

I think somebody is going to end up locking themselves out of the system and/or not be able to re-configure?

until there is a fail safe procedure I would not do anything hasty, in regards of disabling anything. what happens is wifi is lost for good, how do you go about getting back again?

oh certainly, I'm not going to adjust anything until I hear a solution from admin. Just noticed those were there.

There IS a reset procedure...

OK, so I have disabled the provisioning SSID on my Nano-SD, seemingly without ill effect.

Firstly, this is at your own risk, unsupported by Meteobridge etc etc.
It should be safe as it executes a standard Linux command to turn off, and part of the wireless init script on reboot explicitly turns it on.
If you want to do this, I would recommend taking backups of everything first!!


So, firstly SSH into the Meteobridge Nano SD and issue these commands:

Code: Select all

cd /tmp/mnt/data/scripts

echo "#!/bin/sh" > no-ssid.sh
echo "#" >> no-ssid.sh
echo "### Turn off provisioning SSID" >> no-ssid.sh
echo "#" >> no-ssid.sh
echo "ifconfig ra0 down" >> no-ssid.sh
echo "" >> no-ssid.sh

chmod +x no-ssid.sh
This will change to the scripts directory, create a custom script to turn off the interface that is bound to the SSID and set it as executable.

Next, logon to the Nano SD web GUI as normal, go to the Services tab and create a new service:
"Script Execution" "Periodical"

Then set the time period to something appropriate, I used 30 minutes, and on the "predefined script" dropdown,
select "script:no-ssid.sh"
Press the "reload script" button and save.

Check by pressing the Test button for that event; the Live Data tab should say that the script executed correctly and after a minute or so, the provisioning SSID will cease :twisted:
Then every 30 minutes, the command will get issued to turn the provisioning SSID off.

If you need to get into the provisioning SSID, just reboot the Nano and it will reappear (until it reaches the service time set above, then the script will execute and turn off)
Alternatively, SSH in and type

Code: Select all

ifconfig ra0 up
and the provisioning SSID will reappear after a minute or so

Enjoy :D

why run this every 30 minutes? does the SSID enable itself every so often?

Perhaps Boris could build this into the WebGUI so you can shut it "down" but a reboot will bring it back up again.

I wanted it to run 30 mins after boot, but couldn't see a run-once option in the GUI.
I didn't want to put something in rc.local as it may have got overwritten...

Ideally this would be in the GUI, but until it is, this work-around works for me.

Awesome tip, thanks!

Just did this, and it SEEMs to have worked. My reading of Boris's description though makes me think it might be recreated at 5m intervals (but maybe only if the Nano can't reach the internet).

I'm actually amazed that the unit can both provide an ad-hoc network, AND be joined to a wifi network at the same time.

Thanks!

Ok, done some further investigation on this.

In normal events, the 5 minute check will check connectivity and if the ping check fails, it restarts the networking stack.
This will recreate the provisioning SSID as it brings up ra0.
I confirmed this by blocking pings through my gateway.

Actually this is good behaviour - if there are connectivity issues, then I would want the provisioning SSID to be restored in case there are other issues.
The 30 minute no-ssid.sh event will take it back down again next time it runs though.

In normal events, the 5 minute check passes the ping check and the provisioning SSID does not get restored.

There are a few other systems that can do this and what's more doesn't require an App either
