These last couple of weeks we've started having issues where internet has died completely - at first I thought our ISP had issues which they indeed have sometimes.

But when they have issues, they always announce the problem and gives SMS updates when the technician is working on the issue and when it's fixed.

Anyhow. When it started happening basically every day and without any ISP announcements, and quite short downtimes, I ran over to the router when the network died - and noticed something strange. All LED lights died on the router, then turned orange and then back to normal (blue as they should be). Basically, the router did a reboot. 

When I now started going through the system logs on the router, I can see each time the router rebooted and normal start up of services and what not. Along with that I can see a couple of reoccurring error codes which has been logged with close intervals since basically forever. Not sure why the problem would start just now when the error messages has been logged every now and then since I got the router. But if the error messages are not related, why would my router restart seemingly at random? I cannot see any logs indicating any other failures before the router reboot itself.

To mention a couple of error messages:

• Led Controller - Error Code 936: (288753) Config importing failed
• Led Controller - Error Code 937: (288753) Config importing failed
• Led Controller - Error Code 938: (288753) Config importing failed - This being logged 5-6 times a minute since last year.
• Led Controller - Error Code 939: (288753) Config importing failed
• Led Controller - Error Code 940: (288753) Config importing failed
• Led Controller - Error Code 941: (288753) Config importing failed

Exported state:

2020-02-18 11:25:53 led-controller[938]: <3> 288753 Config importing failed

I haven't found any way to find out what the error codes actually mean - is there a list of error codes and their explanation somewhere I haven't been able to find yet?

Any other suggestions?

Feel free to ask me any further questions, I realize my explanation might be a little fuzzy :)

Oh! Forgot to mention, the router is less than a year old running the lastest available firmware.

Thanks in advance!
