Review on Enhanced ViewSonic WPD-100 USB Wireless Adapter (802.11 b/g/n) for PJD7383i, Pro8400, Pro8450w, and Pro8500 by Sam Lund

If you are purchasing this adapter to connect to a ViewSonic projector so you can project images without having to connect to a computer, YOU WILL PROBABLY BE DISAPPOINTED. I urge you NOT to buy. The user manual is useless. It doesn't even mention that the adapter plugs into the projector (come to think of it, that's the important part). It is never shown or demonstrated how to use the adapter. How to connect the adapter to a computer to connect it to a wireless network takes 75 pages, which is only part of the required setup. ViewSonic DOES NOT ACCEPT RETURNS on this item (this should be your first notice). The "technical support" they provide is ridiculous. Don't waste your time. Don't waste money. It is better to spend time and money connecting a network cable to the projector.
