How to Update Router Firmware Safely (All Brands)

Router firmware is the software that runs your router. Updates fix security holes, improve stability and sometimes add features, so keeping it current is one of the best things you can do for your network.

Router firmware is the software that runs your router. Log in to the admin page, open the firmware or update section, click Check for updates, and wait for the router to restart.

Most modern routers can update themselves. Older ones need a manual update from the admin page. Here is how to do both safely.

How to update router firmware automatically

Log in to your router admin page. Find the address with our Router IP Finder, or try 192.168.1.1 or 192.168.0.1.
Open the firmware, update or system section. The location for each brand is in the table below.
Click Check for updates. If a new version is found, start the update.
Wait until the router restarts on its own, usually 3 to 10 minutes. Do not unplug it.
Turn on automatic updates if your router offers it.

Run the update while connected by Ethernet if you can. A WiFi connection drops during the update, which can make it look stuck.

The Ethernet-first tip is the one I never skip when an update is running.

Where the update option lives by brand

Brand	Where to find it
TP-Link	Advanced, System Tools, Firmware Update
Netgear	Advanced, Administration, Firmware Update (or Router Update)
ASUS	Administration, Firmware Upgrade
Linksys	Connectivity, Basic, Router Firmware Update
D-Link	Management, Upgrade
Huawei	Advanced, System, Software Upgrade
Mesh systems (eero, Deco, Nest)	Automatic, or in the app settings

The brand row is the one I check first when the menu does not match the guide.

How to update firmware manually

Find the exact model and hardware version on the router label, for example Archer C6 v3.
Download the matching firmware from the manufacturer support site only.
Unzip the file if needed. Log in to the router and open the firmware upgrade page.
Choose Browse or Upload, select the file and start the upgrade.
Wait for the restart, then log in and confirm the new version number.

The hardware-version check is the step I double-check before any manual update.

Safety rules

Never unplug the router or close the page during an update.
Match the hardware version. Firmware for v2 can damage a v3 router.
Back up settings first from the backup or configuration page.
ISP routers are often updated by the provider. Manual updates may be blocked.
If the update fails, restart the router and try again. If it will not boot, use the brand recovery mode or contact support.

The never-unplug rule is the one I repeat most before any update starts.

How often to update

Check every few months, or turn on automatic updates. If your router no longer receives updates at all, it has reached end of life, and replacing it is the safest choice. For me, the auto-update switch is the setting I turn on and forget.

Signs your router firmware is out of date

Most people only think about firmware when something goes wrong, and it’s often the reason it went wrong. A few things point to an update being overdue:

The router status page shows a firmware date that’s more than a year old.
Newer phones or laptops connect, then drop for no clear reason.
WiFi 6 or WPA3 options you’ve read about are missing from the menus.
The router app keeps nagging about an update you’ve been ignoring.
Your router maker posted a security notice for your model.

Also check whether your model still gets updates at all. If the last release was several years ago, the maker has probably stopped supporting it. That’s usually the moment to start thinking about a replacement, especially if the router is your only line of defence against the internet.

The year-old firmware date is the sign I look for first on any router I check.

If an update fails or the router won’t boot

A failed update is rare, but it’s worth knowing what to do before you need it.

Wait a full 10 minutes. Some routers reboot two or three times during an update and look dead in between.
Turn the router off at the wall for 30 seconds, then on again.
If the lights still look wrong, hold the reset button for about 10 seconds to restore factory settings.
Log in with the default details on the label and try the update again, this time with a cable plugged in.
Still stuck? Many TP-Link, ASUS and Netgear models have a recovery mode. Search your model name plus “firmware recovery” on the maker’s support site.

Before any manual update, take a photo of your WiFi name, password and any port forwarding rules. If you end up resetting, setting things back takes five minutes instead of an evening.

The photo-of-settings tip is the one I never skip before a manual update.

What firmware updates actually change

It’s easy to think of firmware updates as optional extras. In practice they’re closer to the security updates on your phone. A typical release does some mix of these:

Patches security holes that let attackers take over routers from the internet.
Fixes WiFi drops with specific phones or laptops.
Adds features like WPA3, mesh support or a new parental controls page.
Improves stability so the router needs fewer restarts.

Routers sit online 24 hours a day and are a favourite target for botnets, which is why an unpatched one is a real risk rather than a theoretical one. If your router has an auto-update option, it’s one of the few settings worth turning on and forgetting about.

The botnet risk is the reason I never let a router sit unpatched.

Firmware on ISP routers and mesh systems

If your router came from your internet provider, you often can’t update it yourself, and that’s normal. The ISP pushes updates remotely, usually overnight. If you suspect it’s out of date, a restart sometimes triggers a pending update, and support can tell you which version you should be on.

Mesh systems like Deco, eero, Orbi and Nest WiFi handle firmware through their apps and update every unit together. Leave the app’s automatic updates on, and don’t unplug satellites while an update is rolling out across the system.

Third-party firmware such as OpenWrt or DD-WRT is another option for supported routers. It can add features and keep old hardware patched for longer, but it’s for confident tinkerers. A wrong file can brick the router and will usually void the warranty.

The wrong-file warning is the one I take most seriously with third-party firmware.

FAQs About Update Router Firmware Safely

Usually 3 to 10 minutes. The internet drops while it runs and the router restarts at the end. Don’t switch it off in the middle, even if the lights look odd.

Normally no. Your WiFi name, password and port forwards stay put. A few major updates do ask for a reset afterwards, and the release notes will say so.

Yes, for most homes. Updates usually install overnight, and you get security fixes without having to remember. If you run anything that can’t go offline, schedule them for a quiet time.

Automatic updates from the router itself are fine over WiFi. For a manual update from a downloaded file, use an Ethernet cable if you can. A dropped WiFi connection mid-upload is one of the few ways to break a router.

Log in to the router and look on the status, system or administration page. The router’s phone app usually shows it too, under device info or settings.
