Summary: We've used at least fifty of the previous item with this model number. They work. I ordered one of these since I needed another. It never worked. Tried on Linux, Windows 7, Windows XP. I think that we got winxp to notice it. However, it never was more than an entry in the USB table.
Summary: As others have mentioned - either D-Link changed the product without changing the Model, breaking compatibility in the process, or these have a high defect rate. Tried it with Ubuntu 12.04, Mac OSX 10.7.8, and pfSense 2, all of which other earlier reviews mention working "out of the box".
Summary: The product I received works well although it is not what I ordered. What I ordered is pictured above and it is an ethernet adaptor with four additional usb ports built in. The product I received is an ethernet adaptor, but it does not have the four additional ports.
Summary: Did not work for my computer using windows XP, contacted tech support, they didn't know what to do either and installing driver didn't work. Anything can have a good price BUT if it doesn't work, it will never be worth it.
Summary: I purchased this for my intel iMac with a non-functioning ethernet port. The adapter is automatically recognized and will hook to the network with zero configuration. Communication speeds are fast.
This product is awesome. Can be used for regular Windows 98

Summary: At first, I thought that the computer didn't recognized it. I have Windows 98 and I had used another adapter with a plastic door but it broke. This product is very good and got it started after half an hour.
