works smoothly

on 6/19/2006

Using this in a 5 year-old Dell running Windows 2K. Installation was smooth, and reception is very good. My router is a standard Linksys 802.11g unit in a basement, and the computer with this card is on the second floor. I don't get 54Mbs, but I get 20 or 30Mbs, which is faster than my broadband internet connection - so I'm happy.

Quirky. Recommended if your situation is ideal

by Mark on 9/13/2006

I bought this on price figuring that WiFi cards should be a commodity item these days. After a few days I did get it working consistently, but I had the same experience as another reviewer who said it had trouble picking up a signal where his laptop worked fine. Here is some more detail and what worked for me in setting it up. My access point is a Belkin b/g router. I did not expect any trouble with signal strength since my laptop shows (albeit using 802.11b) that I have three neighbors, none closer than 400', all with a "bar or two" of signal strength. All I needed to do was reach upstairs to the other side of the house. I was surprised that the Trendnet card reported none of my neighbors in the "available networks" and very low signal for my own access point. Worse, it seemed to periodically try to reassociate with a neighbors network even though it wouldn't list it. I failed to find a way to configure it to only associate with my own network, but I set it to only use "infrastructure" nodes. I moved the access point to the same room where I have an ethernet jack on another wall. That helped a little. Then I made two changes that finally gave me a reliable connection (sorry I didn't do a scientific investigation): (1) I repositioned the access point a foot or so still closer (to the other side of the cabinet it's in), and (2) I switched off "use Windows to configure this connection" and used the Trendnet property pages exclusively. The situation would probably have been a lot better if the computer faced the access point, for example on an inside wall with the access point in the next room.
