What Is WPS (WiFi Protected Setup)?

by Priya Nakamura Updated Apr 12, 2026

WPS (WiFi Protected Setup) is a router feature designed to make connecting devices to WiFi easier. Instead of typing a password, you can press a button on the router or enter a short PIN. However, WPS has known security vulnerabilities.

How WPS Works

WPS offers two methods: Push Button (press the WPS button on the router, then connect from your device within 2 minutes) and PIN (enter an 8-digit PIN displayed on the router). Push Button is reasonably safe; PIN is the vulnerability.

Why You Should Disable WPS

The WPS PIN can be cracked through brute-force attacks in hours. This gives attackers your WiFi password regardless of how strong it is. We recommend disabling WPS and using WPA3 instead.

Pro Tip: DNS is often called the phonebook of the internet. Switching to a faster DNS can improve your perceived internet speed significantly.

Key Takeaways

Private IPs (192.168.x.x, 10.x.x.x) are used inside your home network
DNS translates domain names to IP addresses
DHCP automatically assigns IPs so you don't have to
Your default gateway is your router's IP address

Frequently Asked Questions

Should I turn off WPS?

Yes. The WPS PIN is a known security vulnerability. Disable it and connect devices by typing the WiFi password instead.

What does the WPS button do?

Pressing the WPS button temporarily allows any nearby device to connect to your WiFi without entering the password. It's convenient but can be a security risk.
