That thing. It's sold under a variety of Brand/Model names. The two I bought for CDN$22.50 each are "Blanc Networks BW-54R11" branded. But the more common variety in the USA is apparently the "GigaFast WF719-CAPR".
It's a bog-standard single-antenna 802.11B+G Wifi router. Runs Linux (2.4.18) internally, and has a decent web config GUI. Range is *excellent*, despite only a single (installed) antenna (there's a solder pad inside, for a second one).
Did I mention it was *cheap* ? I got two of them. One thing it can do, after upgrading firmware to v1.4.1, is a decent WDS function. Combined Client/AP on one channel, so I'm currently connected to one acting as a repeater, which is relaying to the other one upstairs acting as the actual router/gateway to the xDSL connection here (inlaws' house).
Okay, so I'm easily amused.
But if you ever need another Wifi access point (AP), and see one of these on the shelf, rest assured that it is very capable and great value for the money.
EDIT: more info here.
