not running interface

RouterOS Scripting
1

Is there a way to see if interfaces are running or not? (My AR5213s are often not running, but a disable-enable solve the problem)

This one for ethernet:

the “R” next to the wireless interface name (running) means that there is somebody connected and not that the interface has problems. JFYI

:global u
/interface wireless monitor wlan3 once do={
  :set u $status
  }
:if ($u != "running-ap") do={
  /interface wireless disable wlan3; /interface wireless enable wlan3
  }
5 
:global u
/interface wireless monitor wlan3 once do={
  :set u $registered-clients
  }
:if ($u = "0") do={/interface wireless disable wlan3; /interface wireless enable wlan3}

Sorry for “gravedigging” but this post showed up quite high when searching for “wireless enabled not running”.

Therefore I add my variation to the script above, running on routerOS 6.39.2 . Maybe it helps someone else other than me. And, you know, it can be even triggering Cunningham’s law.

# worked
# somehow the wifi of the hAp is recently disconnecting too often. 
# I understand restarting the system after 60 days (or maybe not?)
# but restarting it because the wifi dies every other day is a no go.
# So let*s make a watchdog
# Also forum.mikrotik.com/viewtopic.php?t=2301
:global regClients;
#no underscores!

interface wireless monitor wlan-server-home once do={
  :set regClients $"registered-clients" ;
}

:if ( $regClients  = "0") do={
#disable from slave to master
  /interface wireless disable wlan-server-home; 
  /interface wireless disable wlan-server-hl;
  /interface wireless disable wlan-main-server;

  /delay 5s;
  
#enable from master to slave
  /interface wireless enable wlan-main-server;
  /interface wireless enable wlan-server-hl;
  /interface wireless enable wlan-server-home; 
}

also a scheduler is set to check every 12 hours. (maybe too slow)

Thank you for sharing. Your script works like a charm

add comment=etherwatch timeout=1 interval=30s host=(your ip connected on the ethernet) down-script=“/interface ethernet disable ether 0”
