How to Install Wireguard on a Router for Faster and Safer Browsing

Have you ever wished you could protect all the devices on your home network with a VPN, without having to manually set up VPN apps on each one? Well my friend, that is exactly what installing a VPN on your router allows you to do!

In this guide, I‘ll walk you through step-by-step how to set up Wireguard VPN on a compatible router. Wireguard is a next-gen protocol that provides both security and speed. Let‘s get started!

Why Run a VPN on Your Router?

Running a Virtual Private Network (VPN) on your router instead of individual devices has some great benefits:

Secure every device on your network – Our homes are filled with Internet-connected devices from game consoles and streaming boxes to appliances and security cameras. Most don‘t have native VPN support. A router-level VPN secures them all.

Faster speeds – Routers have more memory, storage and better network hardware like antennas and gigabit ethernet ports. This means faster throughput compared to running VPN apps on phones, laptops and tablets.

Easy to setup – Configuring the VPN just once on your router is far simpler than manually installing and configuring VPN apps across all your devices.

Mask your identity – Your router‘s IP address will show when browsing the web rather than unique device IPs, providing an extra layer of privacy.

According to a survey by Avast, homes in the US have an average of 20 connected devices. Most people are unaware how exposed many of these devices are to privacy and security threats when they connect straight to the internet.

Here are some examples of devices and use cases benefiting tremendously from router-level VPN protection:

• Smart home gadgets – Google Homes, Amazon Echos, smart bulbs and switches often have weak default security with vulnerabilities regularly discovered. They continuously send data back to manufacturers which could reveal activities inside your home.

• Gaming consoles – Modern Xboxes, PlayStations and Nintendo Switch consoles don‘t make it easy to install VPN apps. A router VPN protects against DDoS attacks when gaming online and prevents your ISP from seeing what games you play.

• Streaming devices – Media streamers like Roku, Fire Stick and Apple TV can reveal your watching habits. A router VPN prevents this data gathering and unblocks geo-restricted content.

• Webcams – Security cameras and baby monitors are prime targets for hackers. A VPN adds a layer of encryption to prevent snooping.

So if you, like most people, have an assortment of Internet-connected devices at home, installing a VPN on your router is a no-brainer for blanket protection and privacy.

Why Wireguard Beats Other VPN Protocols

There are different protocols that VPN services use to create encrypted tunnels. Popular choices include OpenVPN, IKEv2/IPSec and WireGuard. Here‘s why Wireguard stands out from a speed and security perspective:

Lightning fast speeds – Wireguard achieves significantly faster speeds compared to OpenVPN and IKEv2 because of its efficient codebase and modern cryptographic standards. Some real-world speed tests:

• Wireguard: 200-400 Mbps
• OpenVPN: 30-70 Mbps
• IKEv2: 60-90 Mbps

State-of-the-art encryption – Wireguard uses Curve25519 for key exchange, ChaCha20 for encryption, and Poly1305 for data authentication, all considered top-of-the-line cryptographic standards.

Minimal, secure code – The protocol is implemented in just 4,000 lines of code making thorough auditing and bug detection easier. OpenVPN has over 100,000 lines of code.

Efficient connections – Wireguard establishes connections much faster and keeps them alive with less overhead resulting in lower latency. OpenVPN has to re-negotiate connections periodically.

Peer-to-peer architecture – Devices connect directly to each other. Traffic doesn‘t flow through centralized servers under complete control of the VPN provider, improving privacy.

Cross-platform support – Apps are available for Windows, macOS, iOS, Android and Linux. It‘s built directly into newer Linux kernels.

The main current limitation with Wireguard is lack of support from many VPN providers. But leading services like Mullvad and AzireVPN have started adopting it due to its clear advantages. Let‘s see it in action!

Step 1 – Install DD-WRT Router Firmware

To set up Wireguard on a home router, you will need to install DD-WRT third-party firmware. This replaces the default vendor firmware with an open-source alternative that adds tons of functionality like VPN support.

Here are the step-by-step instructions to flash DD-WRT:

1. Check if your router is supported by looking through the DD-WRT database. Some popular models that work great include:

   • Linksys WRT3200ACM
   • Netgear Nighthawk R7000
   • Asus RT-AC68U
   • TP-Link Archer C7

2. Download the right DD-WRT firmware file for your router from the downloads page. You want the .bin file, not .img.

3. Access your router admin interface in a web browser. The default is usually 192.168.1.1. Under Settings, turn off any automatic firmware update checks.

4. Navigate to the Firmware Upgrade section. This is normally under Administration or Advanced Settings.

5. Select the DD-WRT .bin file you downloaded earlier.

6. Start the upgrade process and wait for it to flash the firmware. Don‘t interrupt the upload!

7. Once the router reboots, log back in and do a factory reset under Administration.

Refer to the DD-WRT installation guide if you need any model-specific help. With the open source firmware installed, you‘ve unlocked a ton of functionality like VPN support.

Step 2 – Configure Router Settings

Before we set up Wireguard, we need to change some default settings in DD-WRT‘s web interface:

1. Set unique WiFi SSIDs – Navigate to Wireless > Basic Settings and change the default network names for your 2.4Ghz and 5Ghz bands. Pick something unique.

2. Change WiFi passwords – On the same page, update the wireless passwords to be long and complex. Don‘t use defaults.

3. Disable SPI firewall – Head to Security > Firewall and turn off the SPI firewall. Wireguard needs it disabled.

4. Set custom DNS servers – Under Setup > Basic Setup, set preferred DNS servers under Network Address Server Settings. Use Cloudflare (1.1.1.1, 1.0.0.1) or Google (8.8.8.8, 8.8.4.4).

5. Configure time – While on the Basic Setup page, select your time zone and add pool.ntp.org for automatic syncing under NTP Client.

With those basics configured, we‘re ready for the fun part – installing Wireguard!

Step 3 – Install the Wireguard VPN Package

DD-WRT has Wireguard available as a plugin VPN package that needs to be downloaded and activated:

1. Navigate to the Services tab and scroll down to the VPN section.

2. Check if WireGuard VPN is listed under Available VPNs. If not, head to the Software page and click Check For Upgrades. Install any available VPN packages.

3. Once WireGuard appears as installable, click on Install.

4. Wait for the package installation to finish. DD-WRT may reboot.

5. You should now see WireGuard enabled as a running service under Installed VPNs.

The plugin provides the necessary kernel modules and management interface. Next we‘ll generate and configure the actual VPN tunnel.

Step 4 – Generate Wireguard Configuration

Rather than manually creating all the keys and configuration, we can use StrongVPN‘s handy script generator to set everything up in one step:

1. Visit the StrongVPN Wireguard site and log into your account.

2. Click on the router icon and pick the VPN server location you want to use.

3. Enable the "Exclude LAN" option under Advanced to prevent network loopbacks.

4. Click Generate to create your unique Wireguard router config.

5. Copy the script contents from the box at the bottom.

We‘ll import this config into the router next. StrongVPN really makes it simple by giving us the complete setup in one script!

Step 5 – Install the Wireguard Config Script

Now we‘ll transfer the Wireguard config into DD-WRT:

1. In the DD-WRT interface, navigate to Administration > Commands.

2. Paste the script you copied earlier into the Commands box.

3. Click Save Firewall. This saves the script as /tmp/wg.sh.

4. Click Edit to modify the script.

5. Delete the unnecessary "sleep 60" and "reboot" lines at the end.

6. Click Save Firewall again to save the changes.

7. In the Command box, type:

   sh /tmp/wg.sh

8. Click Run Commands. This will install Wireguard and all the keys.

If you see any errors, verify you saved the script properly in steps 3-6. Otherwise installation was a success!

Step 6 – Configure and Connect the VPN Tunnel

The VPN is installed but we still need to activate and configure the connection:

1. Head to VPN > Wireguard > Configuration.

2. Note down the "Public Key". This uniquely identifies your router.

3. Scroll down and check Enable under Tunnel Activation.

4. Select any other options like Kill Switch to block internet if the VPN goes down.

5. Click Apply Settings.

After about 30 seconds, check the Client Status. It should change to Connected with an assigned VPN IP from the provider.

Visit ipleak.net and verify your IP matches the VPN server‘s location to confirm encryption is active.

You did it! Wireguard is now securely encrypting all traffic from your home network.

Step 7 – Configure Additional Privacy and Security Features

Here are some other optional settings to consider under the Policy Routing and General Settings tabs:

• Policy routing – Force only select devices to use the VPN tunnel by entering their LAN IP or MAC address. Useful for privacy sensitive devices.

• Kill switch – Blocks internet access if the VPN connection drops. Leave disabled to avoid unwanted outages.

• Split tunneling – Allows excluding certain apps or destinations from the VPN tunnel like local network resources.

• Disable IPv6 – Stops IPv6 traffic leaks if your VPN provider doesn‘t support IPv6 routing.

• DNS settings – Set custom DNS servers to route all queries through the VPN tunnel.

Troubleshooting Common Wireguard Issues

Here are some solutions for frequent problems that may come up:

Can‘t access web interface – If DD-WRT stops responding at 192.168.1.1 after installing Wireguard, it may have switched IP subnets or lost connectivity. Try resetting the router to factory defaults by holding reset button for 30 seconds.

Slow speeds – First disable Kill Switch and check speeds without VPN active. If still slow, log into router and check for QoS or bandwidth limiter options and disable them. For consistent fast speeds, upgrade to a dual-core router model.

VPN won‘t connect – Verify the router has internet access by connecting a device directly via ethernet. Ensure VPN subscription is valid and double check keys were entered correctly under Configuration. Try restarting the Wireguard service.

Web interface not loading – An incorrect GUI language may cause pages not to load properly. Reset language under Administration > Management. For other issues, perform a factory reset.

Seeing ads or malware – Factory reset the router, reflash DD-WRT firmware, change all passwords and only visit web interface directly rather than via links. Scan devices with malware tools in case they are infected.
