Before you start
Back up important data, use official support instructions for your exact device, and stop if a step requires credentials, firmware, wiring, or disassembly you do not understand.
Steps
Change administrator credentials
Use a unique router administrator password and disable remote administration unless you knowingly secure it.
Update firmware
Use the official router app or admin page to install supported firmware updates.
Use WPA2 or WPA3
Choose WPA3 when every device supports it; otherwise use WPA2-AES and avoid obsolete modes.
Create guest networks
Use guest access for visitors and isolate compatible smart-home devices when the router supports it.
Disable insecure services
Turn off WPS, unused port forwards, and unknown remote-access features.
Review connected devices
Rename known devices and investigate anything unfamiliar.
Document recovery
Record model, admin address, settings backup, ISP support path, and reset instructions.

Buying checklist

- Confirm the exact product, model, and compatibility requirements.
