Bug in Archer C9 logging function
Bug in Archer C9 logging function
2020-03-10 22:01:10
Model: Archer C9  
Hardware Version: V5
Firmware Version: 1.2.4 build 2019.04.03 rel 63869 (4555)

I am trying to troubleshoot some disconnet issues that I am seing on my C9 using the system log, but there seems to be a bug in the logging categorization. Most log entries are classed as "Led Controller" when they clearly are not related to that function. This makes the log function hard to use for troubleshooting, Is there a fix?

@Janbon 

 

We can do further troubleshooting to locate this issue and try to figure it out. 

 

1. What is the led status of Archer C9 when it stops working? 

 

2. Do both wired connection and wireless connection have the same issue? Please login to the web UI of Archer C9 when you lost internet and show us a screenshot of the Advanced-status page. 

 

3. WIth computer connected to the modem directly, bypass the C9, can you access internet normally?

 

4. Please ensure that the firmware of the router is up to date.

 

5. Besides, have you ever setup LED control feature? 

 

Good day.

@Kevin_Z hi Kevin, thanks for the quick reponse on this matter as well.

 

I have experienced disconnects quite frequently the last couple of months, and they are not related to my uplink. I have a fiber connection that works very reliably. I have verified this by connecting directly to the fiber"modem". The disconnect affects both wired and wireless clients of the C9. I've notice an notice in the log stating "flush conntrack succeded" from "basic security" when the disconnects occur.

 

 Most disconnects have been during the days where the LED Control - status lights are on. I have had them turn off at night. From what I remeber, the lights have all been blue during the disconnects, but i will check if it happens again.

 

i believe I do have the latest firmware version available 1.2.4 (2019.04.03) or is there a later version?

 

 

yesterday i did a factory reset and restored my settings, so i am hoping that fixed the problem, but i will get back with screendumps if the problem reoccurs.

 

i am getting an error in the log that puzzles me as well: Led Controller Error: "config importing failed" what does that refer to?

@Janbon OK, now it happened again. 
 

i am attaching some screenshots. It seems like the C9 drops its wan ip and recovers by itself, but not until i have logged on to the admin interface. I get the flush conntrack message again?
 

BTW: I cant find the wan dhcp lease info ?

@Kevin_Z 

I have the sam problem.

I simply don't get it, only way to get internet connection is to restart the router, or release+ renew internet.

Did  the engineer find a solution in your case?

 

thanx for any answer
