I purchased this small USB wireless adapter about a year ago, and this has been the worst product that I have ever bought. At least up until they released a new driver for the device which really works!!
This adapter used to drop its connection frequently so it was almost unusable. I have never been able to transfer a 300MB file using this wireless connection because it dropped connection while the file was being copied. I have tried it in 4 different machines and 5 different OSes including Windows XP, Vista, Server 2003, 2008, and Ubuntu, but same result. It dropped its connection in a random interval – sometimes 20mins somtimes days.
I even requested RMA for this product and got a replacement unit but it did the same thing. At this point I decided to give up and get another one if I need.
About a month ago, I was checking some driver update and found D-Link released a new driver!!! I installed it on Windows Vista machine and never had that connection drop issues yet. Tried Windows XP and it worked like a charm.
If you have connection issues with this device, try the new driver from D-Link!!
