D-Link DI-524 Wireless Router Review

We bought this router to hook up a second computer in a house with a rather spread out floor plan.  We were worried that the second computer would be too far away but this D-link router works great.  It was a little challenging to hook up.  I build my own computers so I consider myself fairly tech savvy but getting this to work took a bit of trial and error.  One thing we did have problems with was securing the network.  We never did get that to work, but it was unclear whether that was a problem with the router or the fact that one computer was an older machine with Windows XP instead of Vista.  We have now bought a second wireless adapter and added a third computer to the network with no problems.  The router works great and the D-link adapter that came with the router works great. The new adapter was Netgear and we had no problems with that either.  We still have never gotten the security function to work despite many trials, but again it may be the computer rather than the router.
