What happens to connected devices when I change the WiFi password?

All devices that are currently connected will disconnect immediately. They need to reconnect manually with the new password. This includes phones, laptops, smart TVs and any smart home devices.

How to Change Your WiFi Password - Step by Step for Any Router | wifi.tips

Q: How do I change my WiFi password?

Log in to your router's admin panel by typing its IP address (usually 192.168.1.1 or 192.168.0.1) in a browser. Go to Wireless or WiFi Settings, find the Password or Key field, enter your new password and save.

Q: What makes a good WiFi password?

At least 12 characters, mixing letters, numbers and symbols. Avoid common words, your name or your address. A random passphrase like 'purple-lamp-42-desk' is easy to remember and hard to guess.

Q: I forgot my WiFi password - how do I find it?

On Windows: go to Network settings, right-click your WiFi, select Status > Wireless Properties > Security tab, check Show characters. On Mac: open Keychain Access and search for your network name. Or log in to your router admin panel - the password is shown there.

Changing your WiFi password is a two-minute job. You log in to your router's admin panel, find the Wireless settings and type in your new password. All routers work the same way - only the interface looks different.

To start, you need your router's IP address (usually `192.168.1.1` or `192.168.0.1`), your admin username and password (on the sticker on the router) and your new WiFi password ready.

Step 1 - Log In to Your Router

Open a browser on a device connected to your WiFi.
Type your router's IP address into the address bar. Try `http://192.168.1.1` or `http://192.168.0.1`. Fritz!Box users: try `http://fritz.box`.
Enter your admin username and password. Both are usually on the sticker on the bottom of your router.

Step 2 - Find Wireless Settings

Once logged in, look for one of these menu items:

Wireless (TP-Link, Netgear)
WiFi or WLAN (ASUS, Huawei)
Wireless Settings (D-Link, Linksys)
Home Network (Fritz!Box)

Click it. You see your current network name (SSID) and password.

Step 3 - Change the Password

Find the Password, Key, Pre-Shared Key or WPA Password field.
Clear the current password and type your new one.
Click Save or Apply.
The router applies the change. All connected devices disconnect.

After saving, reconnect all your devices with the new password. Start with your phone - if it connects successfully, the password change worked.

What Makes a Good WiFi Password?

A strong WiFi password is at least 12 characters long. Mix letters (upper and lower case), numbers and a symbol or two. Avoid:

Your name, address or date of birth
Common words like "password" or "internet"
The router's default password (change it from the default)

A passphrase works well: three or four random words with numbers, like `lamp-42-purple-desk`. Easy to type on a phone, hard to guess.

Router-Specific Notes

Fritz!Box - The WiFi password is called WLAN key (WLAN-Schlüssel). Find it under Home Network > Network > WLAN.

TP-Link - Go to Wireless > Wireless Security. The password field is labeled Wireless Password.

ASUS - Go to Wireless > General. The WPA Pre-Shared Key field holds the password.

Huawei - Go to WLAN > WLAN Basic Settings. The password field is labeled WPA PreSharedKey.
