How to Update Your Router Firmware: Step-by-Step for Every Brand

Your router is the gateway between every device in your home and the internet — yet most people never update its firmware. That’s a serious mistake. Outdated firmware leaves your network exposed to known security vulnerabilities, causes mysterious connection drops, and prevents your hardware from reaching its full performance potential. This guide walks you through the process for every major router brand.

Why Updating Router Firmware Matters

Router manufacturers release firmware updates for three core reasons:

• Security patches: In 2018, the VPNFilter malware infected over 500,000 routers running unpatched firmware across 54 countries. A timely update would have blocked it entirely. Routers are a prime target for botnets like Mirai because most people never update them.
• Performance improvements: Updates frequently include better WiFi throughput, improved range, lower latency, and fixes for devices that drop off the network unexpectedly.
• New features: WPA3 security, parental control enhancements, QoS refinements, and improved compatibility with smart home devices are often delivered via firmware — free upgrades to hardware you already own.

Security researchers recommend checking for firmware updates at least every 3–6 months, and immediately any time a CVE (Common Vulnerability and Exposure) is published for your router model.

Before You Begin: Two Important Safety Rules

1. Never unplug the router mid-update. Cutting power during a firmware flash can permanently brick the device. The process typically takes 2–5 minutes — wait until it’s completely done.
2. Use a wired connection if possible. Updating over WiFi risks the connection dropping mid-flash. Plug your laptop directly into the router with an Ethernet cable for the most reliable experience.

It’s also worth saving your router’s configuration before a major update — some routers reset to factory defaults after large firmware version jumps. Look for an “Export Settings” or “Backup Config” option in the admin panel before you start.

How to Find Your Router’s Admin Panel

Most traditional routers are managed through a browser-based admin interface. To access it, you need your router’s IP address:

• Windows: Press Win+R, type cmd, and run ipconfig. Look for “Default Gateway” under your active network adapter.
• Mac: Go to System Settings › Network › your active connection › Details. The “Router” field is your gateway IP.
• Shortcut: Try typing 192.168.1.1 or 192.168.0.1 directly in your browser — these are the two most common default addresses.

Log in with your admin credentials. If you’ve never changed them, check the label on the bottom or back of your router for the default username and password.

Step-by-Step: Updating Firmware by Brand

Netgear (Nighthawk, Orbi)

Go to routerlogin.net (or orbilogin.com for Orbi) in your browser. Navigate to Advanced › Administration › Firmware Update. Click “Check” to let the router search for updates automatically. You can also use the Nighthawk app on iOS or Android, which often prompts you when a new version is available. Netgear’s Orbi mesh systems support automatic firmware updates — enable this under the same menu.

TP-Link (Archer, Deco)

Visit tplinkwifi.net or 192.168.0.1 in your browser. Go to Advanced › System › Firmware Upgrade and click “Check for Updates.” The Tether app provides the same capability on mobile and supports enabling automatic updates — highly recommended. For Deco mesh systems, firmware is managed exclusively through the Deco app.

ASUS

Navigate to router.asus.com in your browser and go to Administration › Firmware Upgrade. ASUS routers support an “Auto Firmware Upgrade” toggle on this same page — turn it on and the router will update itself during low-traffic hours. You can also manage updates through the ASUS Router app.

Linksys (Velop, Hydra)

Open a browser and go to 192.168.1.1. Navigate to Connectivity › Router Firmware Update. The router will check for the latest version from Linksys servers. The Linksys app handles updates for Velop mesh nodes and often flags available updates automatically.

Eero (Amazon)

Eero has no browser admin panel. All management — including firmware — is done through the Eero app. The good news: Eero updates automatically by default. You can check your current firmware version by going to Menu › Software Version in the app. There is no manual update trigger; Amazon controls the rollout schedule.

Google Nest WiFi & Google WiFi

Like Eero, Google Nest WiFi is fully managed through the Google Home app. Updates are automatic and you cannot trigger them manually — Google pushes updates to all devices on its schedule. You can check the software version under the device details in Google Home.

How to Check If Your Firmware Is Already Current

After logging into your admin panel, your current firmware version is usually displayed on the main dashboard or status page. Compare it against the latest version listed on your manufacturer’s official support page (search for your model number + “firmware download”). If they match, you’re up to date.

Enable Automatic Updates

The easiest way to stay secure is to turn on automatic firmware updates. Most modern routers support this — the option is typically in the same firmware or administration section described above. The router checks for updates at night and installs them during low-traffic hours, rebooting itself when done. You wake up to a more secure, up-to-date device with zero effort.

What If the Update Breaks Something?

Rarely, a firmware update introduces a new bug. If your WiFi behaves worse after an update, check the manufacturer’s support forums — others will report the same issue if it’s widespread. Most brands allow you to roll back to a previous firmware version by manually downloading the older file from their support site and flashing it through the admin panel. If you’re still having trouble after updating, it may be worth checking your router settings and placement as well.

Keeping your firmware current is one of the fastest, easiest things you can do to improve both your network security and WiFi performance. Set a calendar reminder every three months — or better yet, enable auto-updates today and let your router take care of itself.
