Give your router new superpowers by installing DD-WRT

Frustrated by the software limitations on your router? Go ahead and replace that software with the Linux-powered DD-WRT firmware. Maybe you want to use an old router as a second access point for your home network, or as a Wi-Fi bridge. Maybe you want more precise control over how your bandwidth is used — so you can prioritize bandwidth for your gaming sessions — or perhaps you just hate the firmware that came with your router and want something with more features.

Whatever you want your router to do, odds are that DD-WRT can do it. Installing DD-WRT can be complicated, but the most common method includes using the “upgrade firmware” functionality built into your router’s default firmware.

That said, there’s is no universal way to install DD-WRT. Different routers require different versions of the firmware, and many require specific steps. We can’t even begin to outline all of these in a single article. Instead, we’re going to outline how installation works in the easiest cases, while also explaining where to find the correct information should you encounter more advanced scenarios. Let’s get started.

Make sure your router is compatible with DD-WRT

The first thing you need to do is ensure that your router is compatible. Head to the DD-WRT database, then type in the exact model number of your router. This database will tell you your router is one of four things:

Supported, which means you can install DD-WRT. This is signified by a green “yes.”
A work in progress, meaning you can’t install DD-WRT right now but people are working on making it work. This is signified by a yellow “wip.”
Possible in theory, but no one is working on it, meaning you can’t install DD-WRT. This is signified by a red “no.”
Impossible to install, because of hardware limitations, meaning you can’t install DD-WRT. This is signified by a grey “not possible.”

Odds are that your router isn’t supported if it isn’t listed here, but you could also try searching the DD-WRT wiki, or simply Googling your router model number followed by “DD-WRT.” Note that “close enough” doesn’t work — you need the exact model number. Often, a different letter or number in a model name can signify and entirely different router.

Back to the database. For this article we’re going to install DD-WRT on an old Linksys e1000 v2.1, as a demonstration. Here are our database results:

As you can see, our router is supported. But knowing that isn’t enough. To install DD-WRT, you need to find out about any specific steps your router might require, and you also need to be absolutely certain you’ve found firmware compatible with your router. This brings us to our next step.

Knowledge is key

It’s important that you read as much as possible before downloading the firmware. The router database often contains outdated information, sub-par firmware, or otherwise doesn’t tell you the whole story. More information is always necessary.

From the database’s page for your router, click the link to the wiki. Read the instructions there, if there are any. If there is a forum post linked to, read through that as well. See if anyone has had any trouble installing the firmware, and read other people’s suggestions for solving them. You should also, if possible, find out which firmware users have had success with most recently. Router threads will usually offer downloads that are known to work, with other users confirming that they work. You want to know about that before proceeding.

This sounds like a hassle, but there is a non-zero chance you’ll brick your router without complete information, so take the time to read as much as possible. In many cases, you’ll discover firmware that you can simply download and flash, but the process will be much more involved than that for many other routers. If that’s the case for your device, you need to know, and you need to completely understand the extra steps before proceeding.

To give you an idea of what I mean, let’s get back to our example: the Linksys e1000 v2.1, an older router we hope to flash. The firmware offered by the router database was intended for the Linksys e1000 v2, which is similar to but not identical to v2.1. It sounds like a small difference, but simply installing the firmware offered could have bricked the router. We found the proper firmware in a forum thread, after doing our reading.

It bares repeating: don’t skimp on the research. Once you’re certain you’ve found firmware that precisely matches your router, and that you understand the steps necessary for installation, go ahead and download it. But don’t download anything until you’re sure.

Beginning installation

If your router is currently in use, we’ve come to the dangerous part. You need to unplug everything plugged into your router, including the power supply.

Now we’re going to reset your router to factory settings. How to do this will vary from router to router, so we recommend you consult the official documentation before proceeding. Typically, however, this involves unplugging your device and holding down the “reset” button on the back of the router for 30 seconds.

Install DD-WRT from your router admin page

IMPORTANT: The following instructions assume that the research you did in step two told you to simply flash the firmware using your router’s default upgrade tool. This is sometimes not the case, so make sure you’ve done your reading before continuing. If you don’t, YOU MIGHT BRICK YOUR ROUTER.

Once your router is reset, plug it back in to its power supply and connect to it from your the computer you used to download the firmware earlier. You can either directly connect with an Ethernet cable, or via Wi-Fi. Also, remember that you previously reset your router to its factory settings, so the network’s name has changed to the default. Consult your router’s manual if you’re not sure what that is.

Now you need to connect to the router’s admin page which, in most cases, means typing “192.168.1.1” into your browser’s address bar and entering the default username and password. Consult your router’s documentation if that IP doesn’t work, or if you’re not sure what the username and password are. Alternatively, check out our list of default username and passwords for routers.

Now we get to the fun part. Find the “Firmware Upgrade” section on your router — which is typically found under “Administration” or something similar — and click the “Browse” or “Choose file” button. Select the firmware you downloaded earlier, then go ahead and tell the firmware to upgrade. Again, only do this if you confirmed this is the proper procedure while researching.

Patience is essential at this point. The firmware will upload to your router, which will then restart. Do not unplug it, or turn it off, until all the lights come on, which may take a while. Unplugging things too early could brick your router, so wait.

Eventually, you should be able to connect to your router at 192.168.1.1, and log into DD-WRT for the first time, assuming you were connected via a cable. If you were connected wirelessly, you should eventually see a Wi-Fi network titled “dd-wrt.” Connect to it, then head to 192.168.1.1 to configure your router.

If you see the DD-WRT login screen, you need to do what’s called a 30/30/30 hard reset to ensure there is absolutely nothing in your router’s Nvram. While the router is still plugged in, hold down the “reset” button for 30 seconds. Keep holding it, then unplug the power supply, and continue hold the button with the power disconnected for 30 seconds. Continue holding it, plug the power supply back in, and only release the reset button 30 seconds after you’ve plugged the router in.

Connect once again from your computer, then head to 192.168.1.1 to finally begin configuring your router. If everything went well, you can start exploring all sorts of new options! The DD-WRT wiki offers instructions for achieving all sorts of things, from bridged Wi-Fi networks to using QoS to prioritize particular traffic. Be sure to check everything out.
