Changing the Wi-Fi name (SSID) or password is straightforward, but every wireless device using the old details will disconnect as soon as the router applies the change. Planning the order avoids the common situation where you save the new password and immediately lose the admin page.
Before you change anything
Know how to reach the router again. If possible, make the change from a computer connected by Ethernet. Record the current SSID, security mode, and any separate 2.4/5/6 GHz names so you can reverse the change if a legacy device stops connecting.
Open the wireless settings
Sign in to the router or manufacturer app and look for Wi-Fi, Wireless, WLAN, or Network settings. The exact menu is model-specific. Avoid instructions that claim every router uses the same path.
Choose a useful network name
The SSID does not need to contain your address, surname, or apartment number. A neutral recognizable name is easier to identify without revealing unnecessary personal detail.
Set a strong Wi-Fi password
Use a long, unique passphrase and modern security supported by your devices. WPA2-Personal with AES remains widely compatible; WPA3-Personal improves protections when all required devices support it. Many current routers offer a WPA2/WPA3 transition mode for mixed households.
Reconnect deliberately
After saving, reconnect the device you are using first. Then update phones/computers, streaming devices, printers, cameras, and IoT devices. A guest network can use a different password so visitor access does not require changing every household device when it is rotated.
Admin password is separate
Changing the Wi-Fi password does not necessarily change the router administrator password. Review the admin credential separately and keep it out of guest QR codes.
