How to Update Router Firmware (And Why It's Critical)
Router firmware updates patch security vulnerabilities - but most routers don't update automatically. Here's exactly how to check and update your router's firmware.
Router firmware updates patch security vulnerabilities - but most routers don't update automatically. Here's exactly how to check and update your router's firmware.
Your router runs software (firmware) that controls everything it does - firewall, DNS, WiFi, traffic routing. Like any software, router firmware has security vulnerabilities. Manufacturers release firmware updates to patch these vulnerabilities. If you never update your firmware, you accumulate unpatched security holes that attackers can exploit.
Note: TP-Link is under federal investigation. Updates are still worth installing as an interim measure while you plan a replacement. 1) Log in to your router at 192.168.0.1. 2) Go to Advanced → System Tools → Firmware Upgrade. 3) Click "Check for Updates" or download the latest firmware from TP-Link's website and upload it manually.
1) Log in to your router at router.asus.com or 192.168.1.1. 2) Go to Administration → Firmware Upgrade. 3) Enable "Check for update" and click Check. Asus routers can also enable automatic updates - strongly recommended.
1) Log in at routerlogin.net or 192.168.1.1. 2) Go to Advanced → Administration → Firmware Update. 3) Click Check. Netgear Orbi uses the Orbi app - go to Settings → Router Update.
Eero, Google Nest WiFi, Starlink, and most ISP-provided gateways (Xfinity, AT&T, Verizon) update automatically. You do not need to manually update these routers. However, these updates happen on the manufacturer or ISP's schedule - not immediately when a vulnerability is found.
Check for firmware updates every 2–3 months if your router doesn't auto-update. Also check immediately if a critical CVE is announced for your router model - these are typically reported on security news sites and the manufacturer's security advisory page.
Yes, briefly. Router firmware updates typically require a reboot, which disconnects the internet for 1–3 minutes. Schedule updates during a time when the disruption is acceptable. Do not cut power during a firmware update.
Log into your router admin panel and check the current firmware version against the latest available on the manufacturer's website or the in-router update checker. Many routers show "Up to date" when current.
Very rarely. Legitimate firmware from the manufacturer is tested before release. Do not install firmware from unofficial sources. If a firmware update fails partway through (due to a power outage during the process), the router may need a factory reset. Never cut power during a firmware update.
If your router is end-of-life, the manufacturer may not offer newer firmware - your router is showing the latest available, which is simply the last version before support ended. In this case, you need a new router, not an update.
