The Home Sharing feature in iTunes on my home network seems to be very hit or miss. This includes Home Sharing from computer to computer, iPhone Apple Remote App, Computer to ATV2, and computer to iPhone. Sometimes, it all works fine and sometimes nothing will connect and the libraries can not be found. One second everything is fine, then I will do something like go to use the Remote App and it will not find the library that it was just connected to a minute ago. I'm wondering if this could all be related to DHCP assigned IP addresses. If I set up static IP addresses for everything will they have less trouble communicating and be more consistent in maintaining connections? Before I go thru all the trouble of setting up static IP's on everything, I was hoping someone with a bit more network knowledge than me might know if this would likely help. The following devices are on my home network regularly: Macbook Pro ATV2 Roku XBOX 360 2 iPhone 4 iPhone 3G Airport Express 4 PC's that only get occasional use Like I said, sometimes everything works fine, but then sometimes it will just suddenly stop connecting. Then sometimes it seems to just fix itself without me doing anything. Othertimes, I go thru steps like closing and reopening iTunes, logging off the network with the various devices involved and then logging back on, etc. and am able to get my connections back. I'm wondering if these issues are cause when any given device goes to "sleep" and disconnects from wifi and then rejoins the network with a different IP. Would this explain what is occurring?
