Your router is the front door of every device you own, and most are still using the factory password from the box.
Updated August 09, 2026, after a fresh review, with updated visuals and links.
These six fixes take half an hour, protect everything behind them, and never need touching again. Let's harden the door.
Short version: Change the admin password first, then upgrade to wpa3 (or at least wpa2). Details below.
How to do it
- Change the admin password. Log into 192.168.1.1 or 192.168.0.1 with the sticker credentials and immediately set a new admin password in the system or maintenance section. Factory passwords are public knowledge, and this login rules your whole network.
- Upgrade to WPA3 (or at least WPA2). In Wireless settings, set the security mode to WPA3 Personal, or WPA2/WPA3 mixed if older gadgets complain. WEP or 'Open' networks are open invitations with a password shaped illusion.
- Disable WPS. WiFi Protected Setup (the push button or PIN method) has known attacks that crack networks in hours. Find the WPS toggle, turn it off, and add devices by typing the password like it's 2010, secure and simple.
- Update the firmware. Check Administration or System for a firmware update button. Router security holes get patched exactly here, and most routers never update themselves unless you press it. Some newer models auto update: confirm yours is enrolled.
- Kill remote administration. Any setting named Remote Management, Remote Access or WAN administration should be OFF. Your router should only listen to devices inside your home, not the internet at large.
- Create a guest network for visitors and smart gadgets. A separate SSID with its own password keeps friend phones and cheap smart bulbs away from your laptops and drives. Compartmentalization is free security: one compromised bulb no longer endangers the family photos.
Small tweaks, big difference
- Rename the network to something that doesn't reveal your router brand or your address: 'TP-Link_A4X2 house of the Smiths' is marketing for attackers.
- Reboot the router monthly (many have scheduled reboots in settings), updates apply and stale states clear.
- Write the new admin credentials on paper taped under the router: physical access to the box already beats all passwords.

WPA3 breaks my old printer. What now?
Use WPA2/WPA3 mixed mode: strong where possible, compatible where needed. Security and the printer coexist.
