The problem of interoperability

Bought an Apple AirPort Express to connect my laptop with my stereo to listen music and at the same time be able to browse the web.  Since I have a Fonera router for using my network and sharing it with others (not that anybody has actually connected as I live in the middle of nowhere), I thought it would be easy to have them talk to each other and to my PC… how wrong I was!

After 3 hours of fiddling with the different settings I got it all working and now I'm happy listening to music without any wires in the way.  However, it got me wondering about the good old problem of interoperability.  Even when following the same standards, it is ridiculous things wouldn't work because of an arcane problem between WPA/WPA2 implementations in the two routers.  I guess there is still plenty of work to be done.
