The old style Airport Expresses are amazing and have been around a long time, they are great for extending your home network and also great for setting up impromptu networks when travelling.
However, as of Mountain Lion the Airport Utility (which is now pretty dumbed down) doesn’t support them which is kind of lame – I guess when the devices once had an expected life of 18 months that isn’t much of a surprise.
There is however still a solution, AirPort Utility 5.6 for Mac OS X Lion, which of course you can’t install on Mountain Lion until you find these excellent instructions.
From frustrated to happy in the space of 5 minutes, now I can get this Tiger running Mac Mini from 2006 back online alongside the new Mac Book Air that replaces it.
Now I just need to see if I can set the second one up for my in-laws too so they can get iPlayer on the TV
