Come back, I opened up, and was surprised to find it as Version 2.0. Version 3.0 seems to have been out for a few months already, yet Version 2.0 are still being sold. The thing is, from the outside of the box, you have no way of knowing if it is Version 1, 2 or 3. You need to open up and look at the label on the underside of the device.
From the looks of things, the WRE54G isn't moving too well, since the Version 3 has been out for a while now, and yet, Version 2 are still on the shelves. There was one box where the serial number was older. If I have picked that one up, I might have end up with a Version 1 instead, and Version sucks because it doesn't have an ethernet port for you to confiture the device.
