Hi all, I know this topic has been covered before and there is a support page for this problem on the apple website but I haven't been able to fix the problem using either hence the post so sorry for repetition. As the title says my airtunes keeps cutting in and out, but it only seems to happen when I am actively using the internet. What I mean to say is that if the internet is connected and sitting there dormant it works fine, but as soon as a start to surf or download it cuts out, the higher the download/upload rate the longer the cut outs are until it stops all together. My network contains the following, 2 Computers (1 iMac and 1 MacBook Pro) 1 Airport Express The iMac is the host of the network, it also is the provider of the internet via a USB mobile broadband stick shared out via Airport (which cannot be connected directly into the Airport Express). Airport Express is used purely for Airtunes. I could not change the channel setting to test for interference in Airport Utility as the iMac was the host. I tried changing the whole network channel on the iMac but the cut outs still occurred. I use the MacBook Pro to send the audio from iTunes to Airport Express, distance would only be about 4 meters with no physical barriers such as stereo/cables/walls etc. Any suggestions would be much appreciated. Cheers, Jarrod.
