Since DD-WRT is open source, it‘s completely free to install and use. And it supports a wide range of router hardware – over 500 models according to the official DD-WRT database. Popular compatible brands include Linksys, Netgear, Asus, and more.
To date, DD-WRT has been installed on over 2 million devices worldwide based on estimates from DD-WRT developers. It‘s the most popular custom router firmware option available.
Key Advantages of Using DD-WRT
Here‘s a closer look at some of the best reasons to install DD-WRT:
Boosted Wireless Performance
One major benefit is enhanced WiFi range, speeds, and connectivity. DD-WRT gives you granular control over radio transmission power, channels, antennas and more. This allows you to optimize wireless settings for your environment.
Many users report DD-WRT improves their WiFi range and throughput substantially compared to stock firmware. It reduces dead zones and lag. According to a study by researchers at Johannes Kepler University, test routers saw 2x gains in throughput after installing DD-WRT firmware.
Prioritize Bandwidth Usage
Ever wanted to make sure your video calls or gaming devices get top priority on your network? The QoS engine in DD-WRT allows granular prioritization of traffic.
You can ensure latency-sensitive applications like online gaming or VoIP get precedence. This prevents lag and choppy calls on your network.
Built-in VPN Server
DD-WRT makes it easy to configure your router as a VPN server. This encrypts and routes all traffic from your network through an encrypted tunnel for enhanced privacy and security.
The VPN server works with protocols like OpenVPN, WireGuard, PPTP and L2TP. Enabling it protects all connected devices from prying eyes on public WiFi or insecure networks.
Enhanced Security
In addition to VPN server support, DD-WRT also provides hardened security in other ways. This includes an advanced iptables firewall for managing rules and filtering traffic.
There‘s also support for wireless encryption standards like WPA3 for robust over-the-air protection. And you get features like MAC address filtering, DNS caching, and more for building a secure network.
DD-WRT also receives frequent security patches from its active open source community. Stock firmware rarely sees updates leaving you more vulnerable.
Modern and Intuitive Interface
Managing settings on stock router firmware feels dated – the UI is often unintuitive and clunky.
DD-WRT provides a clean and modern interface that‘s easier to navigate. Everything is cleanly organized into sections like wireless, services, administration etc. And there are handy tools like real-time bandwidth usage monitoring.
Overall, DD-WRT just makes router administration much more user friendly.
Active Development and Updates
As an open source project, DD-WRT sees frequent updates and new releases from developers. Bugs get fixed, new features get added, and security issues get patched quickly.
Compare this to stock firmware that rarely sees meaningful updates over time. The active development behind DD-WRT keeps it at the cutting edge.
Step-by-Step DD-WRT Installation Walkthrough
Ready to get your hands dirty? Follow this simple guide to install DD-WRT on your router:
Prerequisites
Before we start, make sure your router and computer meet the requirements:
- Verify router model is supported by checking the DD-WRT database. Installation will fail if unsupported.
- Router must have at least 8MB flash memory and 64MB RAM for DD-WRT.
- Reset router to factory defaults in admin interface or with reset button. This wipes current config.
- Computer connected via Ethernet cable recommended. Can use WiFi but may lose connection.
- Disable any auto firmware upgrade features in admin interface.
Download DD-WRT Firmware
First, we need to download the DD-WRT firmware file for your router:
- Visit DD-WRT Downloads page
- Find your router model and download the latest
.binfile - Also download the matching
.chkchecksum file - Save these two files to your computer – I recommend Desktop or Downloads folder for easy access
Reset Router to Factory Defaults
Before installation, your router must be reset to factory defaults:
- Locate the reset button on back/bottom of router
- Use a paperclip to press and hold reset button for 30 seconds
- Router will reboot back to stock firmware and settings
- Run setup wizard and set a new admin password
This clears any customization and reverts firmware to factory condition – crucial for DD-WRT install.
Access Router Admin Interface
With router reset, let‘s access the admin interface:
- Open web browser and enter your router‘s default IP – usually 192.168.1.1 or 192.168.0.1
- Enter your newly set admin password when prompted
- Navigate to Firmware Upgrade section (may be under Advanced tab)
This is where we‘ll upload and install DD-WRT.
Install DD-WRT Firmware
Inside the firmware upgrade page of admin interface:
- Select the DD-WRT
.binfile you downloaded - Check "Keep settings" if you had any custom config
- Click Upload to start the installation process
Installation will take 5-10 minutes as router reboots and flashes DD-WRT. Do not interrupt installation or you risk bricking!
Reconnect to Router Post-Install
Once router finishes rebooting:
- Try reconnect to 192.168.1.1 web interface
- If unable to connect, manually set computer IP to 192.168.1.x and netmask to 255.255.255.0
- This ensures you‘re on the right subnet to access router admin
- Accept new DD-WRT terms and proceed to web interface
Hooray, DD-WRT is now installed! But we still need to configure all our settings.
Configure DD-WRT Settings
Under DD-WRT‘s clean new interface:
- Navigate to Setup tab and set new username and password
- Go to Wireless tab and reconfigure your SSID and wireless security
- Setup DHCP server settings like IP ranges and lease times
- Recreate any port forwarding, firewall rules, or QoS you need
- Enable VPN server if desired for routing traffic through a tunnel
And you‘re all set! DD-WRT is installed and configured. Enjoy your router‘s new superpowers!
Comparing DD-WRT to Other Firmware Choices
DD-WRT is the most popular custom firmware option – but not your only choice. Here‘s how it compares to alternatives like Tomato and OpenWRT:
Tomato – Lightweight option focused on ease of use. Great UI and QoS. More limited featureset overall.
OpenWRT – Very minimal and targeted at advanced users. No GUI – managed via SSH. Extremely configurable but complex.
DD-WRT – Offers a good balance – full suite of advanced functionality with interface suitable for beginners. The flexibility OpenWRT offers combined with UI friendliness. Clear winner for most use cases.
My recommendation is DD-WRT for its balance of power and usability. But check out other options too and decide based on your needs.
