Best OpenWRT Routers to Buy in 2021 for Unhindered Customization and Performance

By Vaidyanathan Subramaniam / February 5, 2021

While most routers provide a good deal of functionality out-of-the-box, there's still a lot more functionality than can be extracted from the hardware. Custom router firmware aim to provide features that are simply not found in most OEM firmware.

Like DD-WRT and Tomato, OpenWRT is also a popular open-source firmware for many of the popular Wi-Fi routers on the market. In fact, OpenWRT has been around for longer than the other two and offers more fine-grain control over your router's functionality.

However, OpenWRT is not exactly the most user-friendly firmware out there, and using it requires some networking knowledge to get the most out of it. If you are a networking enthusiast and want to check out the best OpenWRT routers available, we've got just the perfect selection of devices for you.

Here are the 6 Best OpenWRT Routers You Can Find in 2021 on the market.

Can I install OpenWRT/LEDE on any router?

Though many routers, including the ones listed above, support OpenWRT/LEDE, you should first check if there are firmware packages for your exact router model. Flashing wrong or incompatible firmware can potentially lead to bricking your router.

Check out the official Table of Hardware to see if OpenWRT firmware is available for your particular model.

What are the minimum RAM and flash storage requirements to install OpenWRT?

OpenWRT recommends a minimum of 4 MB of flash memory and 32 MB of RAM for installation. However, these are absolutely bare minimum requirements and may not fully work with modern OpenWRT versions (above v19.07).

Having higher RAM and storage helps with installing third-party packages and also enabling additional router functionality. It helps to have at least 16 MB flash storage space and 128 MB of RAM for the full OpenWRT experience.

Which OpenWRT build should I download?

OpenWRT is continuously updated with new features and bug fixes. As such, there are two variants currently available — stable releases and development snapshots. Unless you know what you are doing or are interested in testing new features first-hand, we always recommend that you install only the stable release builds for your router at all times.

How do I log in to the OpenWRT interface?

After successfully flashing a compatible OpenWRT firmware, logging in and administering your router is as simple as navigating to from your browser of choice. This opens the LuCI web interface. During the initial login, the username will be root, and the password field will be empty. Make sure to assign a root password after initial login.

Can I install third-party software packages in my OpenWRT router?

Yes. OpenWRT is a highly modular firmware, and you can install additional packages to further extend its functionality. However, you should first familiarize yourself with installing OpenWRT packages as it involves some command line work. Popular packages that are available for a particular router model can be directly installed via the LuCI web interface.

Can I configure my VPN provider with OpenWRT?

Yes. The process may vary slightly depending on your VPN provider but essentially involves installing the OpenVPN package on your OpenWRT router and uploading the .ovpn configuration file from your VPN provider.
