REVIEWS:
1) Not Vista Compatible: This item is excellent overall if you have XP.

However, it is NOT Vista compatible. I found a driver off the D-Link Taiwanese website that got the driver to work, but it still produced annoying errors and the device does not consistently perform in Vista.

It is not likely that D-Link will produce a Vista-compatible driver, since this product has been discontinued.

Do not buy this if you have Vista or are thinking about getting Vista.
2) Not compatible and not returnable: After purchasing this item I discovered it was not compatible with the WPA encryption on my wireless network. But since I had opened the box, the seller refused to accept a return. Make sure you do your research and confirm that this adapter will work for you.
3) A real bargain: Sensitivity is great. This USB 802.11g adapter is regularly able to pick up 4 to 6 times as many nearby APs as any of my PCMCIA based WLAN adapters, and in 3 weeks has never dropped my link, to my knowlege. With Windows in control of it there are almost no config options available. But so far I find no fine tuning needed. The worst thing I can say about this adapter is that it is a little too small and light--the normal springyness of the USB cable makes it unlikely to sit flat on any surface without velcro, and difficult to "aim". But for the trivial price, it"s a real bargain.
4) Never Lets Me Down: I have an company computer that I use to connect to my employer"s VPN. I had been using a Netgear USB wireless adapter, but it would regurlarly dosconnect me from the VPN, and I would have to log on again. I don"t know why it did this, but it was a pain. The Netgear adapter would also get very hot, and I would have to disconnect it from the computer. My D-Link G120 never knocks me off the VPN. It"s great! I work in an upstairs bedroom, and my cable modem and wireless connection are downstairs and 40 feet away, and the G120 reception is fine. I"ve learned my lesson and will stay with D-Link.
5) Not a good product: This wireless adapter didn"t have good signal strength at 25" though I have a new router. Replaced this adapter with a TrendNet adapter (TEW424UB) and getting full strength all the time.
