Linksys WUSB54G - Beware different versions...

I use a Linksys WRT54G router, which has been flawless. It was wirelessly connected to 2 computers with Linksys WUSB 54G adapters... No problem...

 

When I wanted to wirelessly add a third computer, I decided to stick with what had worked for me, the WUSB54G. I thought the interchangeability would be nice. I got a new WUSB54G, installed it, and all was fine... Except...

 

It is a different version of the WUSB54G, and is not interchangeable with the other two. The boxes are exactly the same, the units look exactly the same, except that 2 of them say Version 4 on the back of the unit by the serial number. Only one of the boxes says version 4, so apparently they updated the item before updating the boxes.  I need to return my new one and find a version 4 so I can be the same on all machines....

 

They all worked, they just weren't interchangeable, as you'd expect. This is just an FYI if you value system consistency....
