Solution Optimizing WireGuard VPN Client Connectivity on the M8550
This Article Applies to:
M8550(EU/US)_V1.0/1.6
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 be sure you have read the Beta Test Agreement before upgrading the Pre-release firmware!
- How to upgrade firmware of TP-Link 5G Mobile Wi-Fi
- The Beta firmware could revert to the official 1.20/1.3.0 firmware versions.
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.

Here is the FRA98.conf file:
[Interface]
PrivateKey = CONFIDENTIAL
Address = 172.31.68.193/32, fd00:0000:1337:cafe:1111:1111:a4d5:f33e/128
DNS = 46.227.67.134,192.165.9.158,2a07:a880:4601:10f0:cd45::1,2001:67c:750:1:cafe:cd45::1
[Peer]
PublicKey = CONFIDENTIAL
AllowedIPs = 0.0.0.0/0, ::/0
Endpoint = CONFIDENTIAL
Try importing the FRA98.conf file into your router. Before saving, expand the "Interface" and "Peer" menus underneath to modify the settings manually.
In the Interface section, try changing:
Address = 172.31.68.193/32, fd00:0000:1337:cafe:1111:1111:a4d5:f33e/128
to:
Address = 172.31.68.193/32,fd00:0000:1337:cafe:1111:1111:a4d5:f33e/128 (without spaces)
or just:
Address = 172.31.68.193/32
And if needed, change the DNS line:
DNS = 46.227.67.134,192.165.9.158,2a07:a880:4601:10f0:cd45::1,2001:67c:750:1:cafe:cd45::1
to a single IPv4 and IPv6 DNS,
or just: DNS = 46.227.67.134
In the Peer section, try changing:
AllowedIPs = 0.0.0.0/0, ::/0
to:
AllowedIPs = 0.0.0.0/0
Let me know how it goes! 😉

Essayes d'importer le fichier FRA98.conf dans ton routeur. Avant de valider, ouvre les menus en dessous "interface" et "peer" afin de modifier les informations manuellement.
Dans la partie "interface" essayes de modifier :
Address = 172.31.68.193/32, fd00:0000:1337:cafe:1111:1111:a4d5:f33e/128
par
Address = 172.31.68.193/32,fd00:0000:1337:cafe:1111:1111:a4d5:f33e/128
ou
Address = 172.31.68.193/32
et éventuellement :
DNS = 46.227.67.134,192.165.9.158,2a07:a880:4601:10f0:cd45::1,2001:67c:750:1:cafe:cd45::1
par
DNS = 46.227.67.134,1
Dans la partie "peer", essayes de mofifier
AllowedIPs = 0.0.0.0/0, ::/0
par
AllowedIPs = 0.0.0.0/0
Tiens moi au courrant ;-)

I managed to connect after making some adjustments, thanks
The M8550 is still not a good VPN router. Even with VPN enabled, an unprotected connection was possible (no kill switch)

Hi,
Glad to hear that your VPN connection is established. Regarding the feature request to support the VPN kill switch feature on M8550, I'll log it and forward it to the relevant team for evaluation.
Best Regards
