Alert: there's a twenty-dollar rebate if you buy this from J&R via Amazon before 12/31/2005.

The ZyXEL AG-225H 802.11a/b/g Wi-Fi Finder & USB Adapter (the official name) is a three-in-one device that packs some useful features for the wireless road warrior: it sniffs out access points (APs), it works as a USB wi-fi adapter, and it can turn an Internet-connected Windows PC into an access point!

The package comes with the ZyXEL AG-225H adapter, a Quick Start Guide that describes the finder and wi-fi adapter functions, a software installation CD-ROM for Windows, a USB extension cable, and a wrist strap.

Physically, the adapter is slightly larger than a pack of chewing gum. Its USB connector hides behind a cap. Inserting and removing the cap is a breeze, yet there is enough friction to keep the cap secure. In fact, this has the best balance of friction and ease of insertion/removal I've laid my fingers on; it actually feels good to put on and take off the cap! Unfortunately, the cap is small and, when taken off, can be misplaced very easily.

The ZyXEL has a small b&w LCD screen that shows hotspot info in the finder mode. When connected to a PC, it shows the status of the built-in LiIon rechargeable battery: charging, or full. Under the LCD screen are two blue LED indicators, one for power and the other for wi-fi access indication.

There are two buttons at the top: one for controlling the seek mode (see below) and the other allowing you to scroll through the list of APs. It took me a while to remember not to use the Seek button as "previous," as there is no previous button. You just keep pressing the Next button to cycle through the list of APs. There's a Power switch at the bottom.

I had been looking for a full-function WiFi finder and after reading a number of good reviews, bought it. It is also a USB 802.11g wireless adapter and an access point. I didn't actually need these features (although I might use them later), I was willing to pay extra to get a top-quality finder. I have not been disappointed in this product. I've traveled with it and it has performed as expected, locating all nearby hotspots, even better than my laptop can detect with it's build-in WiFi adapter. Highly recommended if you don't mind the price.

I've been using the ZyXel adapter for a few months now in a mixed PC and Mac environment. And while it is a good little adapter for these sorts of things, it does have shortcomings.

First the positives. I can't tell you how useful having a network finder can be when you're searching for a connection and have limited notebook battery life to burn. Or when you get suckered into setting up a network for a friend who lives in a brick building. The comprehensive information display is better than any I've seen before. It isn't quite realtime... a search takes 5 - 10 seconds in tedious reality, but it is certainly fast enough to speed things up overall.

The battery on this little thing charging Via USB is also very, very nice.

As an adapter the device is perfectly servicable. It is about as powerful as the internal cards you see in a lot of laptops these days. It does require extra software to run, and that software could be better written, but it works and doesn't seem to add too much to system instability. Unfortunately, don't expect to just plug it into a friend's computer and have it run. Under windows, it does everything it says it will, which makes it a powerful little device.

However, the OSX driver currently has some limitations (as of March, 2006). The two units that I purchased required updated firmware to run under OSX, but the updater only ran under Windows. Once updated, it turns out that WPA authentication, a security protocol used by many workplaces, is not supported yet on the mac. Fortunately, home networks can be stepped down to WEP without much loss in security, but business users may be SOL.

The other major flaw is a simple design one: the USB port is small and flakey, and designed to be used back-to-back.
