Is it possible to connect the Squeezebox to a laptop using wifi, without a wireless router? I plan to get the squeezebox but I don't use a wireless router.
I'm not sure if that is possible. What are your requirements? If you want to stream music from your laptop to a speaker wirelessly, you can buy wireless bluetooth speakers.
Looks like it is indeed possible to connect a Squeezebox wirelessly without a wireless router!!

Wireless Ad-Hoc networking
Also known as Independent Basic Service Set (IBSS) wireless networking. The Squeezebox can connect to another wireless device without a wireless router or wireless access point.
For Macintosh systems, on the Airport menu you will find a section about halfway down entitled "Computer-to-Computer Networks". Click on the "Create Network..." option, and it will walk you through the process of creating a network. Write down the SSID (network ID) you enter, so that you can be sure your other devices are connected to the correct network.
