There are two ways to modify the password for the Wavlink router. One way is via the Wavlink smart WiFi app, and the other is through the web interface. However, you must use the Wavlink router setup window to access the administration site for both procedures. Click the Password option after selecting the Security Settings option on that portal. You must log into your router using the default or an older password in order to access that option. Next, create a new password and include some numeric and special characters to make it strong enough. Additionally, take note of the safe location for future login procedures, since you must utilise this one at this time.
