Wireguard Issue (continuous disconnections) ( GL-MT3000 )

Routers
1

Hi all, I'm experiencing constant connection reboots; I'm using wireguard and controld.

I can't figure out why.

FW -> latest stable

I'm attaching the crash log

Hi,

The reason for the VPN disconnects did not find from this log.

Is the connected VPN server self-built or a third-party VPN provider?

When the router VPN client drops, please disable the VPN client, and check the Internet is normal?

Please share whole issue syslog with us.

It crashed without VPN; I uploaded all the logs on the device

Hello,

From the syslog you attached, we found the MT3000 WireGuard client is not disconnected, but the MT3000 detects the radar channel, and triggers the DFS scan, repeater is disconnected and own WiFi is silent during the scan, which causes the wireless client to disconnect.

  1. Is there any WiFi disconnect issue during use of ASUS router when the WiFi bandwidth at 160MHz?

  2. Please try changing the bandwidth of the primary WiFi (ASUS) to 80MHz and select fixed CH36 to reduce the impact from the radar.
