Before updating
Use a stable connection, preferably Ethernet. Do not unplug the router during installation.
- Log in to the router.
- Open Administration, System, or Firmware Update.
- Use the automatic check, or download the exact model and hardware revision from the official manufacturer site.
- Install and wait for the router to restart.
- Confirm settings and internet access.
Protect the recovery path
How to Update Router Firmware can affect the entire network, so record ISP details, SSIDs, reservations, port forwards and special policies before making a disruptive change. Match firmware to the exact model, region and hardware revision, and avoid interrupting a write.
Post-change verification
After the router returns, test the WAN, one Ethernet client and each wireless band separately. Confirm critical services such as voice, VPN, port forwarding or mesh nodes before assuming the maintenance task is complete.
Final verification step
If the manufacturer offers automatic and manual update paths, use the supported path for the exact product. Manual files should be treated as model-, revision- and region-specific. Save the release notes with your maintenance record so later behaviour can be tied to the installed version.
