Thought this might be interesting....
Manufactuer's website says, it can work as USB adapter and in an AP mode as well.

I've always been curious why these are needed. Don't all laptops technically have a WiFi finder built in?

I'm also thinking that, if you don't have a laptop, this will help you troubleshot wifi signal issues.

These are great. I hated to unpack the laptop just to see if there was a signal nearby and find there wasn't. I've tried many other finders, and they rarely did anything of value. I've been using one like this for about 3 years, when they were about $75. Li-Ion battery lasts for months as a finder, and it charges when plugged into the USB port. It shows all the signals in range with signal strength, band, security encryption, and SSID. I also use it for wireless installations to help position equipment. Very handy. The signal strength on this is comparable to what my laptop shows. I like mine so much I bought 5 (rebate limit) of them for gifts when the were on sale about 1 month ago for $12 AR. But this is a good deal too.

This is both a standalone wifi "finder" for A/B/G/N signals and a USB wifi adapter. You can plug it in to your USB port and it will then connect to any signal that it finds (subject, of course, to such either being non-secure signals or ones for which you have a password).

This also can be used as a repeater/access point so that you can share your wireless connection with others. You can be in a group and after you connect to the internet (wired or the laptop's adapter) others can connect to you thru this.

eibgrad said:The SP version is the same as v1.0, neither of which support Vista or the N protocol, you need v1.5 for those features (at least according to Zyxel TS).Is the draft "N" different from "N"? From the Factory site:

The ZyXEL AG-225HSP is the ultimate tool for today’s road warrior. Combining a Wi-Fi HotSpot Finder together with a USB Wi-Fi Adapter makes the AG-225HSP the most versatile wireless tool on the market today. Detecting ALL flavors of wireless networking from 802.11g/b to 802.11a and the new Draft 11n standard, the AG-225HSP truly is a jack of all trades. Small enough to fit in your pocket, powerful enough to be used by the most demanding of users, the ZyXEL AG-225HSP is the perfect tool!

NOTE THAT THIS DOES NOT WORK IN VISTA!!!!

Dimensions 3.8" x 1.1" x 0.6"
Weight 0.1 lbs.

That's huge?

microwiz said:The thing I'm wondering is, I've seen pictures of an "AG-225H V2" out there. It has a form factor more like one of Zyxel's USB wifi adapters, but most importantly, it has a backlight for the LCD screen, which would make it far more useful. Does anyone know if this one has that? Digging around on both Zyxel's site and Newegg turned up nothing.

Edit: AG-225H V2 from the UKI just broke open one of them I got a few weeks ago, and it is not backlit. Neither is my old one. It can be a bit hard to read in dim light (you have to tilt it toward the light), but you only are looking at it for a minute or so to go thru a list of many sites. It would be nice if it were backlit, but it won't stop you from being able to use it.

What color are the LED scanning-indicator and power-on lights on this thing ? If it is blue, then it is the older model one; if they are green, then the LCD screen lights up and can be read in bad or no light. I have both models, thinking I had lost the original one (lo and behold, only to be refound stached somewhere under my car seat) and ordered another one, which they sent me as the later green LED'ed model.

I suspect that these have been on sale because their manufacturer mistakingly put HSP's in the H package. It's a AG-225H box but the UPC had a bigger UPC sticker on it saying AG-225HSP.
