Sony LF-PK1 LocationFree Player Pak

Pros: For laptop users, a good way of untethering

Cons: Knowledge of router programming is not needed, but required

Summary: Contrary to what the reviewer writes, the unit will stream wirelessly through a WiFi router, but in order to make that work you need to set up a static IP address in both the unit and the router, and do some other fancy stuff. A wireless game adapter, I used one made by Linksys, will work and will free the unit from the Ethernet tether that is otherwise a necessity (my broadband box lives far away from the video equipment). Here again, a lot of setup is involved, and router programming a necessity.

The unit works well, caches probably 60 to 90 seconds of video/audio in order to buffer connectivity problems, and is able to run at its highest data rate on a 10 mbit wireless link, via the game adapter to the router and thence to a laptop (this using composite video, S-video needs more bandwidth). So if you're ready to spend a couple of days futzing with it, you can achieve good results. But if you don't know how to set up a static IP address and change your DHCP address range, or have a good buddy who does, spend your money on something you'll get more mileage out of. Look at it as a cool toy for the nerdy.
