Router Firmware Updates: Why They Matter and How to Check

Phones, laptops, and even smart TVs generally prompt you when an update is available, often insistently. Routers, for the most part, don't — many sit in a closet or on top of a bookshelf, quietly running the same firmware version they shipped with years ago, simply because nothing ever reminded anyone to check.

Why Routers Get Overlooked

Part of it is visibility: a router doesn't have a screen prompting you to update, and checking usually means logging into a web interface or app that most people only open once, during initial setup. Part of it is also that a router "just works" from a user's perspective even when its firmware is years out of date — there's no obvious symptom telling you something's wrong, which makes it easy to assume everything's fine.

What Firmware Updates Actually Fix

Router firmware updates typically bundle a mix of things: security patches closing vulnerabilities discovered since the last release, stability improvements addressing crashes or connection drops some users have reported, and occasionally new features or compatibility improvements for newer device types. The security patches are the part worth paying the most attention to, since a router sits at the edge of your home network, making it a meaningful target — vulnerabilities here can potentially expose every device connected behind it, not just the router itself.

How to Check Your Router's Current Firmware Version

Most routers show their current firmware version somewhere in their admin interface — typically under a "System," "Administration," or "About" section, accessible either through a phone app (for newer mesh systems) or by typing the router's local IP address (often something like 192.168.1.1 or 192.168.0.1) into a browser while connected to the network. From there, most interfaces also show whether an update is available and let you install it directly.

Manual vs. Automatic Updates

Many routers released in the past several years support automatic firmware updates, often enabled by default, which is generally the easier and more reliable option for most households. Older routers, or ones from manufacturers less focused on this, may require manually checking and installing updates. If automatic updates are available on your router, it's worth confirming the setting is actually turned on rather than assuming it is.

What End-of-Support Means for Older Routers

Every router model eventually reaches a point where its manufacturer stops releasing firmware updates for it — sometimes explicitly announced, sometimes simply inferred from the update history going quiet. Once that happens, any vulnerability discovered afterward will never be patched on that specific model, regardless of how well it otherwise still functions. This doesn't mean a router seizes up the day support ends, but it does mean the security posture of that device only degrades from that point forward, since new vulnerabilities in networking software are discovered fairly regularly across the industry.

How to Check if Your Model Is Still Supported

1. Check the manufacturer's support page for your specific model number, which is usually listed on a sticker on the device itself.
2. Look at the date of the most recent firmware release for that model — a multi-year gap since the last update is a meaningful signal, even without an explicit end-of-life announcement.
3. Search for the model name alongside terms like "end of life" or "end of support" to check for manufacturer announcements.
4. If a router genuinely can't be confirmed as still supported and it's several years old, it's reasonable to weigh whether replacement makes sense, particularly if it also lacks WPA3 support.
