http://www.logitech.com/index.cfm/ [...] 8&cl=us,en

They have bluetooth connection. I do have wireless network setup. Can wireless network pick up bluetooth device? Or, I need to stick in usb mini receiver that comes with the kb to the pc, and have it communite with the kb. Is that how it works?

Can i hook up bluetooth device to pc over wireless network if i do not use usb mini receiver?

Please help me out.

Thanks.
