After much stuffing around with DNS Settings, turning off notifications, changing wireless channels on the router and ever other little change that gave me marginal improvements, my YouTube buffer line is getting ahead of the play line and there is now no waiting. For those who run 802.11g routers and have this issue, it is worth trying 802.11n. I had an older d-link 802.11g router that was ok but after searching for a replacement router or combined router, I had an idea to use the Airport Express Base Station (AE) as the main wireless router instead of just being a client to my network for AirPlay to output to the hifi. After 10 minutes of tinkering, I swapped the old router with the AE and tested it. Throughput went up a bit but the streaming effect was huge. The only thing missed when using AE is the lack of browser interface but as a whole it works fine so far. As a bonus, streaming movies from Itunes to my ATV2 is also improved and the movies load a lot faster. The next question is to keep the AE, replace it with another 802.11n router or just buy another AE. I thought about the AE Extreme but I dont see the value. Maybe they will release a new version soon. Anyhow, for improved output to ATV2 or Ipad I recommend giving 802.11n a go.
