You must connect to a new SSID from your computer when it is configured for Ad-Hoc mode.

If you are trying to pair your Lenovo machine to a computer that is already in Ad-Hoc mode and has a configured SSID, use these instructions.

This type of network does not have a central wireless LAN access point/router. Each wireless client communicates directly with each other. When the Lenovo wireless machine (your machine) is part of this network, it receives all print jobs directly from the computer sending print data.
