I have WLAN, laptop is working, only who I want to use cell phone says: no WLAN connection and requires a password. As far as I know I didn't give a password. And everything I've tried is wrong. Does anyone have an idea.

Is under the router (your Wi-Fi source)

Thanks for the quick response. I think the sticker on the router, there's no password, only 20 digit number. Everything always tries wrong…
