[SOLVED] How to know if router has a wlan interface

planetcaravan · Sat Oct 20, 2012 12:38 pm

Hi there,

I want to write a script like this

if ($myRouterHasWlan = true) {run this}
else {run that}

how can I make it in RouterOS?

Try this:

# Check that if we're using a wireless LAN
:if ($usewlan = "yes") do={

or this:

# Check that the WAN interface exists
:if ([/interface find name=$waninterface] = "") do={

{
local wlan [len [interface wireless find]]
if ($wlan>0) do={/system script run script1} else={/system script run script2}
}

change the name of script1 and script2 for your name of scripts

Thanks for you suggestions.
I've created a file named nuova.txt.
I've used

:if ($usewlan = "no") do={/file set nuova.txt contents="no wireless"}

and

{
local wlan [len [interface wireless find]]
if ($wlan<1) do={/file set nuova.txt contents="no wireless"}
}

but both of them don't work. What's wrong?

is working for me:

{
local wlan [len [interface wireless find]]
if ($wlan<1) do={/file set nuova.txt contents="no wireless"}
}

try this:

put [file get nuova.txt contents ]

remember first add a file:

file print file=nuova.txt

I'm using RouterOS 5.21 on a RB750GL.
Loot at the file attached. I've also inserted the line you suggested me.
It doesn't work fo me.
I've tried without this line

put [file get nuova.txt contents ]

but nothing's changing.

Look that, file already exists!

first paste in your terminal this

{
local wlan [len [interface wireless find]]
if ($wlan<1) do={/file set nuova.txt contents="no wireless"}
}

if the output is nothing, is all ok

and see the comment in the file with this

put [file get nuova.txt contents ]

GOT IT!
As my RB750GL doesn't have wireless package enabled, "wireless" command does not will be recognized!
I've enabled the package and all is working fine!

Thanks!
