Model : Archer C1200

Hardware Version :

Firmware Version : 3.0.4 Build 20180122 rel.42880 (US)

Problem: My Archer C1200 keep disconnecting randomly. The leds on the router have no change.
I found that there are some "Initialization" in the system log that match the time of connection drops

Logs created when disconnecting.

@LSM224556 I have the exact same problem with a similar log file - except my device is an Archer C2300 v1.0 with the latest firmware as of 1/7/2020.  Have you found a solution to this?

 

Thnx in advance,

Steve

Hello, we will do some troubleshooting first to locate this issue and try to fix it.


What is the light status of the C2300 when the connection drops out? Can you get internet from it via wired cable at that time? Please connect your device to the modem directly to do a comparison test as well.

Note: Please click here to check the IP address and default gateway with your devices connected to the modem/router separately and show me the status-details page. 

 

At that time, please login to the web UI of the Archer C2300 and take a full screenshot of the Advanced-status page; and go to advanced-system tools-system log  to save and export it to us. 

 

Besides, please follow the instruction below to do some test and tell me which case you belong to.

@LSM224556 I have the same exact issue with Tp-Link Archer c6. Connection drops every 5-10 mins and the log file looks the same ... Do we have any solution to this problem yet?

@DanoPlurana 

 

Ya man, keeps having this issue. At first from the logs it says DOS protection in action and it stops some services. Then i disable it. After a few hours then it happens again, now the last relevant log that it shows flush conntrack table succeeded.

 

Im now disabled the SPI and am monitoring it.
