I picked up an Apple Airport Base Station (Graphite) several years ago, and have only had minor problems with it. Sometimes it would be visible to the iBook but unresponsive/unconnected to the DSL, sometimes it would simply not appear. I'd go into our office and usually find all three lights on solid green. Fixing it was easy, just unplug the power, wait 30 seconds or so, then plug it back it, which usually fixed everything. It has been acting up a little more recently, and decided to just show the middle light lit up solid red. The usual methods to reboot failed. I was fortunately able to jump on someone else's wireless base station on our block to do some searching via Google, and ended up at Hack the Planet: How I Got My AirPort Base Station to Work, which gave me enough info to reboot the base station and reload the software on it. Maybe 5-10 minutes of work, and it was just like new.
