It is important to understand that the process may differ slightly depending on the router model (Archer C6, TL-WR841N, Deco M5 and other devices) and firmware versions. However, the general logic remains the same: you need to go to the device's web interface, find the wireless network settings section, and set a new security key. If this is your first time setting up a router, don't worry—we'll walk you through each step in detail with illustrations and tips.

Please note: after changing the password, all connected devices (smartphones, laptops, smart speakers) will be automatically disconnected from the network. You will need to re-enter the new connection details on each device. We also recommend writing the new password down in a safe place, such as a notepad or a notepad on your phone.
