How do I unlock my network so that I can connect a new notebook?

I have a new notebook, but I can't register or connect it because my network is secured. How do I proceed?

With a normal, 08/15 WLAN you simply enter the WLAN key.

If your WLAN access point (usually the router) has a WPS button, press it and select "Connect via WPS" on the notebook within the specified time period (usually one or two minutes).

Otherwise you have to enter the password. You can first try the sticker on the access point (back or bottom); if this is not the case, it will display it on a device with a connection. (With Windows this is pretty easy with administrator rights, with Android only if it is "rooted" or if you read the memory directly, I don't know iOS well enough)
