NVRAM save before reboot

[Jerry_gsp]

Is it a quick way to save my wifi schedule?
It disappears every time I reboot.

 

[Zirescu]

Did you remember to click Apply afterwards?

A known issue, has happened to me with both factory & Merlin firmware.
Maybe Asus will fix it one day.

Is there a script that can run at startup to fill out the radio schedule?

What router model and firmware version are you using?

You could probably do it by creating a couple of user scripts on the router.

I'm using Merlin's 384.4_2 on a ac86u.
Thanks for the help -

I don't have the same hardware/firmware version as you, but assuming the NVRAM variables haven't changed this should work:

Save your current Wi-Fi schedules:

nvram show | grep -E "wl._timesched|wl._radio_date_x|wl._radio_time_x|wl._radio_time2_x" > /jffs/scripts/wifisched.nvram

Now create a /jffs/scripts/services-start script as follows (or append it to your existing script):

#!/bin/sh

# Create file with "nvram show | grep -E "wl._timesched|wl._radio_date_x|wl._radio_time_x|wl._radio_time2_x" > /jffs/scripts/wifisched.nvram"

while read line
do
    nvram set $line
done < /jffs/scripts/wifisched.nvram
nvram commit

Will try - thanks

Colin,

How will this script be executed automatically at reboot?

There are scripts that run automatically (if they exist) when certain events occur.

It doesn't work.
These are the variables' values I get in the wifisched.nvram file:

It looks to me that they don't cover the entire array for all the hours and days of the week

 

[ColinTaylor]

Can you post a screen shot of your schedule as seen in the GUI. I think I'm misunderstanding what you're trying to do.

This schedule disappears after reboot

 

[ColinTaylor]

Ah I see. We're talking about different things. I thought you were talking about the Wireless Scheduler under Wireless > Professional that looks like this:

What router page are you seeing that schedule? It's possible that my firmware doesn't have it.

 

[Jerry_gsp]

The ac86u is on a new platform - the wifi scheduler is also under wireless - professional but it looks like I showed you

 

[ColinTaylor]

Ah, OK. Sorry, I can't help you as I don't know what NVRAM variables are used now. I've had a quick look at the source code for 384 but it's not immediately obvious what the variables are. Maybe someone else knows.

 

[ColinTaylor]

@Jerry_gsp I may have found it. Can you run the following command from the router's command line:

nvram show | grep wl._ | grep sched | sort

Try these nvram variables

nvram show 2> /dev/null | grep MULTI
