How do you find your wep key for wlan?

To find your WEP key for a WLAN, you can access your router's settings by entering its IP address in a web browser. Typically, this address is something like 192.168.1.1 or 192.168.0.1. Once logged in (using the admin credentials), navigate to the wireless settings section, where you'll find the WEP key displayed. If you cannot access the router, check the device that originally connected to the network, as it may have the WEP key saved in its network settings.
