Just wanted to give you all another update. A couple of days ago my iBook started behaving like the iMac, it wouldn't connect to the network. I figured it had to be the router or similar since both were doing it. I've now got my Airport Express broadcasting the WiFi in our house and the iMac is back online. I've not had an issue with re-connection from either sleep or a cold start. It all seems to be working well.
