What is Your Router’s Firmware?

Your router’s firmware is basically the operating system that is specifically designed to run on your specific make and model of router (unless you are using a multi-router compatible open source firmware such as DD-WRT).

Usually, your router manufacturer will provide firmware updates for your specific make and model of router, via their website, or via a tool within the administrative console of your router (typically accessible via a web browser).

Why You Might Want to Upgrade Your Wireless Router’s Firmware

There are many reasons you may want to consider updating your router’s firmware, here are several of them.

Security Features and Fixes

One good reason why your router manufacturer may put out a firmware update is because they are trying to fix a vulnerability that was detected in the current firmware, updated firmware is similar to system updates (as in Microsoft’s Windows Update). As bugs are found and corrected, updated firmware is released.

Performance Enhancements

Besides security fixes, your router manufacturer may have found a way to enhance your router’s overall performance, which is always a good thing. If you don’t update your firmware then you won’t be able to take advantage of any speed boosting upgrades that your router manufacturer might release in an update.

How to Perform a Firmware Upgrade

Every router is different, but usually, they have a similar process for upgrading the router’s firmware. Here are the basic steps for performing a firmware upgrade, check your router manufacturer’s website for specific instructions for your make and model.

Login to Your Router’s Administrator Console

Each router manufacturer uses different default addresses so check your specific router manufacturer’s website for details on which one your router may be using. Many routers use as this address but it does vary.

Here are some common default addresses fro some of the more popular wireless router brands.

  • Apple:
  • Asus:
  • Buffalo Tech:
  • Dlink: or
  • Cisco/Linksys: or
  • Netgear: or

After you enter the IP address of your router in your browser’s address bar, you will likely be prompted for the administrator name (typically “admin” or “administrator”) and the default administrator password. These credentials can likely be obtained from your router manufacturer’s website or they might be located on a label on the bottom or back of your router, typically located near the serial number of the router.

Locate The Firmware Upgrade Section of the Administrator Console

Download and Install The Router Firmware (from a trusted source)

Newer routers will likely make it very easy to download and install the firmware directly from within the router administrative console. Some routers may require that you first save the file to your computer and then select the firmware file via the administration console.

Regardless of the method, make sure you are downloading directly from the manufacturer or from another trusted source (if using open source router firmware). If possible, scan the file for malware before performing the firmware upgrade.

IMPORTANT NOTE: Don’t interrupt a firmware upgrade that is in progress or you could potentially damage (brick) your router. Try to avoid doing an upgrade during a lightning storm as firmware upgrades and power outages don’t mix well.
