LED Controller Errors in System Logs

Concerned About LED Controller Errors in Your Router’s System Logs?

 

If you have found yourself looking at your router’s system logs when troubleshooting, you may have seen a few entries for led-controllers. These entries can get quite confusing, so make sure to take a look at the below guide to get a better idea of what the different LEDs mean.

 

*Please Note that the LED Controller Notifications in the Log and the Status of the LED are for reference only and should not be overly relied upon due to potential inaccuracies.

 

In the system log of the router, you will oftentimes see notifications given in the following formats:

 

2023-11-20 10:56:16 led-controller[1104]: <6> 288051 Start to run WAN1_ON

2023-11-20 10:56:15 led-controller[1104]: <6> 288051 Start to run WAN0_OFF

2023-11-20 10:56:15 led-controller[1104]: <6> 288051 Start to run LAN_OFF

2023-11-20 10:55:00 led-controller[1104]: <6> 288051 Start to run WAN1_OFF

2023-11-20 10:55:00 led-controller[1104]: <6> 288051 Start to run WAN0_ON

2023-11-20 10:55:00 led-controller[1104]: <6> 288051 Start to run LAN_OFF

 

In simple terms, WAN1 represents the Internet green LED, WAN0 represents the Internet orange LED, and LAN represents the LAN LED. This means that the orange and green LEDs will likely trade positions with each change in connection.

 

• WAN1 – Internet Green LED
• WAN0 – Internet Orange LED
• LAN – LAN LED

 

WAN LED Entries:

Log Entry:	WAN1_ON or WAN0_OFF	WAN1_OFF or WAN0_ON	WAN1_OFF or WAN0_OFF
Indicates LED Status Should Be:	Internet LED is Green	Internet LED is Orange	Internet LED is OFF
Meaning:	Connection Between the Router’s WAN Port and Modem is OKAY; Internet is Accessible	Physical Connection Between Router’s WAN Port and Modem is OKAY, but the Internet Cannot Be Reached.   (Likely Due to WAN Settings, like Bad DNS)	Physical Connection Between Router’s WAN Port and Modem is NOT OKAY Due to Bad Contact.   (Recommended to Change the Cable and/or Port)

 

LAN LED Entries:

Log Entry:	LAN_ON	LAN_OFF
Indicates LED Status Should Be:	LAN LED is On, and Green	Internet LED is OFF
Meaning:	There are Devices Connected via a Wired Connection	There are no Devices Connected via a Wired Connection

 

If you are looking for the specific meanings of the physical LED lights on your router, please see the User Guide for your model as each model will have different LEDs and colors depending on the features and design of your router.
