Hi All,
To address critical reliability and performance issues with the WireGuard VPN client on the M8550, our engineering team has developed a targeted firmware update. This update resolves configuration parsing errors, enhances connection stability, and improves traffic routing efficiency.


It is recommended to install this beta firmware if you happen to experience the following situations:

  • Configuration File Import error: Users are unable to import WireGuard VPN configuration files due to parsing errors or unsupported parameters.
  • Connection Failures: After the configuration file is imported successfully, the VPN tunnel fails to establish a stable connection.
  • Traffic Routing Issues: VPN Client status may display "connected", but VPN traffic can't pass  properly between the client and the remote WireGuard VPN server. 

 


Firmware Download Link:

M8550(US)_V1.6 1.2.0_3.0.0_Build_20260121_Beta
M8550(EU)_V1.0 1.3.0_3.0.0_Build_20260126_Beta

Update Notice:

 


Please feel free to comment below whether the 1.2.0 firmware helps to ensure stable VPN connectivity.
If you still experience any issues with WireGuard VPN Connection on M8550, please feel free to comment below and include a detailed description of the behavior and as much information as possible regarding the specific conditions that seem to trigger it.

Your input helps us continue to improve and provide the best possible products and support.

Hi, doesn't work for me. I'm trying to setup WireGuard with my Asus Router using the tether app. When importing the config file and reentering the dialog, it resets the endpoint IP-adress with an adress from the WireGuard range with subnet mask like 10.6.0.2/32. The title on this section is also VPN-Server and not VPN-Client.

So looks not finished. It shows as connected but no real data went through.

Hi, welcome to the community.

Did you plan to set M8550 as a WireGuard VPN Client for the Asus VPN Server?

(PS: M8550 doesn't support LAN-to-LAN VPN connection.)

As for the VPN Client range, you mentioned M8550 resets it to 10.6.0.2/32. Is this not the VPN client range reserved on the Asus router?

-By the way, can I have the model number of your Asus router?

 

Could you please send an email to support.forum@tp-link.com with the following details:

  • A copy of the WireGuard VPN config file
  • A copy of the web UI system log on the M8550
  • A screenshot of the WireGuard VPN status, such as:

Best regards.
