Troubleshooting
“Firmware file is invalid”
The file is for a different model, region or hardware version. Match the label exactly.
Router won’t start after the update
Wait 10 minutes. Then try a factory reset. TP-Link routers often have a recovery (TFTP) procedure documented on their support site.
Frequently asked questions
How often should I update router firmware?
Check every few months, or enable auto-update. Install security updates as soon as they appear.
Does updating erase my settings?
Usually not, but some major updates reset settings. Note your Wi-Fi name and password first.
Summary
Use the router’s app or web interface to check for updates online; for manual updates, download the firmware for your exact hardware version. Stay wired and don’t interrupt the router while it updates.
