I've been having a few networking issues at home, partly due to my existing router getting on a bit and some new rules it randomly decided to implement to block most of my iTunes streaming and syncing traffic only over the Wireless Network. As a result I had some elaborate system to get ethernet to all of the devices that really needed to talk, ie the iMac iTunes Server and the AppleTV. This still meant that all of the iDevices were blocked out from being used as remotes etc.
This week I finally bit the bullet and got an Airport Extreme and a Time Capsule and put them into play. I have to say it was probably one of the easiest setups I've every had to implement (even for apple products). I picked up both the items from ebay and if the Time Capsule had come up first I probably wouldn't have bothered with the Airport Extreme but the solution is markedly better with both devices. Adding the Time Capsule wirelessly to the Airport Extreme extends the wireless network (genius) and acts as an ethernet bridge.
The only real problem is it now has me thinking about getting an Airport Express so I can Stream to the nicely wired Tivoli Setup.
