VPN Client on Wi-Fi Router Is Not Working

Tags: #VPN #Highlighted Thread #Official #WireGuard

This Article Applies to:

All the Wi-Fi Routers that support VPN Client, such as Archer AX20, Archer AX21, Archer AX90, etc.

Issue Description/Phenomenon:

The Wi-Fi Routers that are being discussed here are the models that support VPN Client, which allows users to connect to a VPN server without the need to install VPN software on each device. If you are unable to connect to a VPN server when trying to configure the VPN client on the TP-Link router, this article provides some suggestions that may help you out.

However, if VPN server on TP-Link router is not working, please follow this thread for troubleshooting: VPN Server Doesn't Work Properly on TP-Link Wi-Fi Routers

Troubleshooting Suggestions & Solution:

Step 1

For OpenVPN, please follow this FAQ How to get configuration files from OpenVPN service providers to get correct configuration file and your VPN service credentials, which is the key to accessing the VPN service.

Step 2
Ensure you can successfully connect to the VPN server using a third-party VPN client software like OpenVPN Connect or OpenVPN or WireGuard App for WireGuard VPN on the local PC/Smartphone. This can ensure the .opvn or .conf file is configured and exported correctly.
For example, If you are trying to connect to NordVPN, please don't use NordVPN App since it doesn't require the .opvn at all.

Note: NordVPN service credentials are different from your NordVPN account credentials, namely your email address and your password. You'll need NordVPN service credentials to connect to the VPN using the manual OpenVPN configuration method in the router.

Step 3
If step 2 is confirmed good, but it still fails to connect to the VPN server when uploading the .opvn file into the TP-Link router, be sure the router's firmware is up-to-date. You can check for the updates on the Tether app or on the router web GUI, or you can download it from the local official website and then install it manually.

Step 4
If it still fails, please check the size of the VPN configuration profile you are trying to upload to the router, and how large that file is. You may download and install the Notepad+ application to delete the useless comment in the profile if that is too large, then try uploading it into the router again.

Step 5
It's also suggested to try TCP protocol on the VPN server if it's currently using UDP, then save the file and upload it into the TP-Link router again to check if that works.

If the VPN connection still fails, please comment below on this topic and be sure to provide the following information:
1. Model number, hardware, and firmware version of your TP-Link Router.
2. What kind of VPN server you are connecting to?
3. What kind of VPN type are you choosing on the TP-Link router, OpenVPN, or PPTP VPN?
4. What kind of VPN Client software you were using on the local PC or phone when it was connecting fine? Please test and make sure you can connect to the server with third-party software, such as OpenVPN Connect for OpenVPN and WireGuard App for WireGuard VPN.
5. Which step did you stuck in, any error message or screenshot?
6. Troubleshooting you've done before, and be sure the .opvn file for OpenVPN or .conf file for WireGuard is included when emailing to support.

If you are not familiar with the VPN, visit Introduction and Configuration Guide of VPN Function on TP-Link Wireless Routers
If you want to check which model supports the VPN Client, visit Routers supporting the VPN Client.

If you are unable to connect CyberGhost OpenVPN Server, please try Manually create the unified format for OpenVPN profile(CyberGhost OpenVPN Server)

@pawker it still dont work..

I have the VX1800v connected directly to the cable from my VDSL provider. Devices are connected to it immediately after. My OpenVPN settings are 100% functional – tested on clients across multiple devices, and the same configuration works perfectly on the AX3000 without any issues.

Please help! Thank you.

Firmware Version:0.13.0 2.0.0 v6092.0 Build 240925 Rel.11089n Hardware Version:Archer VX1800v v1.0 00000000

@Kevin_Z

I have an ARCHER BE550 and my devices are unable to connect to the internet using the NordVPN client.
PINGs do work, but not browsing.
I have tried with Android phones and iPhones, laptops and several other devices, and browsing is impossible when adding these devices to the VPN.
I have updated the Firmware to the latest version of the Forum, but the problem persists.
My router data is as follows:
Firmware Version
1.1.1 Build 20241230 rel.20267(4555)
Hardware Version
Archer BE550 v1.0

I await instructions.

@Kevin_Z

I have just purchased an Archer VX1800v and can't get it to connect to a NordVPN OpenVPN config.

I've tried connecting to a UDP and TCP server that connects fine through the Nord app (Windows).
I've looked in the OpenVPN config file and I don't have any <key></key> sections as mentioned in the accepted response above.
When I try to connect using the OpenVPN Connect client, I get the following error message:

Which I can get around by commenting out the offending ping-timer-rem command from the ovpn file as below, but I'm unable to get this to work on the tp-link device:

The system log doesn't show me (not a network engineer) anything erroneous about the VPN connections.
