How to Change Your WiFi Password on Any Router

Changing your WiFi password is one of the most basic — and most important — things you can do to keep your network secure. Whether a neighbor has been freeloading on your connection, you’ve just moved into a new place, or you simply want to tighten up your security, the process takes less than five minutes on any router.

This guide covers every major router brand, including app-only systems like Eero and Google Nest WiFi, plus tips for choosing a password that’s actually hard to crack.

Before You Start: Find Your Router’s Admin Address

Most routers are managed through a web browser using a local IP address. The most common ones are:

• 192.168.1.1 — Netgear, ASUS, Linksys, and many others
• 192.168.0.1 — TP-Link, D-Link, and many others
• 10.0.0.1 — Xfinity (Comcast) gateways

If none of those work, check the label on the bottom or back of your router — the admin URL is usually printed there. You can also find it on Windows by opening Command Prompt and running ipconfig, then looking for the “Default Gateway” address.

You’ll also need your router’s admin username and password. This is different from your WiFi password. The defaults (often admin / admin or admin / password) are also printed on the router label unless you’ve changed them.

How to Change Your WiFi Password by Router Brand

Netgear

Open a browser and go to routerlogin.net or 192.168.1.1. Log in, then navigate to Basic → Wireless (or Advanced → Setup → Wireless Setup). Find the Password (Network Key) field, enter your new password, and click Apply. You can also do this through the Nighthawk app under Router Settings → WiFi.

TP-Link

Go to tplinkwifi.net or 192.168.0.1. Log in (default: admin / admin), then go to Wireless → Wireless Security. Update the Wireless Password field and click Save. Newer TP-Link routers can also be managed with the TP-Link Tether app.

ASUS

Navigate to router.asus.com or 192.168.1.1. Go to Wireless → General, update the WPA Pre-Shared Key field, and click Apply. The ASUS Router app offers the same option under Settings → Wireless.

Linksys

Visit myrouter.local or 192.168.1.1. Go to WiFi Settings or Wireless, change the WiFi Password, and click Save. Linksys Velop mesh systems are best managed through the Linksys app.

Google Nest WiFi & Google WiFi

These routers have no browser-based admin panel. Open the Google Home app, tap your WiFi network, tap the gear icon for Settings, then tap WiFi password. Enter the new password and tap Save. All devices on your network will be disconnected immediately.

Eero

Eero is also app-only. Open the Eero app, tap the menu icon in the top-left corner, select Network settings, then tap WiFi password. Type your new password and tap Save.

Xfinity (Comcast)

Go to 10.0.0.1 in a browser (credentials are on your gateway label). Navigate to Gateway → Connection → WiFi, select your network, click Edit, update the Network Password, and click Save Settings. You can also use the Xfinity app: Home → WiFi → Edit → Change Password.

Spectrum

Log into your Spectrum gateway (typically 192.168.1.1 or 192.168.100.1). Go to Advanced Settings → WiFi → Private WiFi Networks, select your band, update the password, and click Save. Via the My Spectrum app: Services → Internet → Manage WiFi → Edit.

What Happens After You Change the Password

The moment you save your new WiFi password, every device currently connected to that network will be kicked off. This includes phones, laptops, smart TVs, game consoles, smart speakers, security cameras, and any other WiFi-connected device in your home. You’ll need to reconnect each one using the new password.

A few practical tips to make this less painful:

• Do it when you have 15–20 minutes to reconnect your devices, not right before a video call.
• Write down the new password before saving it so you have it handy.
• Smart home devices (thermostats, doorbells, cameras) sometimes require going through their full setup process again — have their apps ready.
• If you have guests connected, they’ll also lose access. Consider setting up a separate guest WiFi network to avoid disrupting them in the future.

How to Choose a Strong WiFi Password

Now that you’re changing it anyway, make it a good one. A weak WiFi password is an open door for neighbors to steal your bandwidth or, worse, for attackers to access your local network.

• Length is king: Aim for at least 12–16 characters. A 20-character passphrase is far stronger than an 8-character complex password.
• Use a passphrase: Four or five random words strung together (e.g., BlueTruckSunsetPiano) are easy to type on a phone keyboard and genuinely hard to crack.
• Mix in numbers and symbols: Sprinkle in a number or symbol to increase complexity without making it unreadable.
• Avoid personal info: Your address, phone number, birthday, and pet’s name are the first things a motivated attacker tries.
• Use WPA2 or WPA3: While you’re in the router settings, confirm your security mode is set to WPA2-AES or WPA3. Never use the outdated WEP or original WPA standards.

Once you’ve set a strong password, store it in a password manager like Bitwarden or 1Password so you never lose it again.

Frequently Asked Questions

Does changing my WiFi password change my router admin password?

No. Your WiFi password (what devices use to join the network) and your router admin password (what you use to log into the settings panel) are completely separate. Changing one does not affect the other.

Will changing my WiFi password affect my internet speed?

No. The password has no effect on your internet speed. If your speeds are slow, check out our guide on why WiFi gets slow for real solutions.

How often should I change my WiFi password?

There’s no strict rule, but changing it once a year or whenever you suspect unauthorized access is a good habit. Always change it when a contractor, houseguest, or anyone else who shouldn’t have permanent access leaves.
