I'm sure there is a simple solution to this.....
I get internet to my computer via Ethernet cable. When i want to stream music to my Airport Express, I turn on wireless and select Airplay in iTunes. Now my computer streams my iTunes wirelessly to my Airport Express. The problem is that once i turn Airport on, it no longer allows me to browse the internet (via Ethernet).
Is there a way to tell my computer for Internet purposes look at Ethernet, but use the Airport Card to stream music to my Airport Express?
