My broadband is pretty appalling at home so I took the decision yesterday to purchase a MiFi device on the basis that I am cancelling my phone line and broadband package with Sky so I can just use the MiFi or my iPhone unlimited data for the internet. I tested the MiFi yesterday and everything seemed fine. Apple TV plays videos from Netflix, my Ps3 let me play online with no issues so I thought I had found a solution to my slow internet, but then I tried to access my music on my Apple TV and the home sharing would not work. I have checked and iTunes is configured to allow home sharing, the setting is also checked on the Apple TV itself so I cannot figure out what is wrong. I have also noticed that my Airport Express connected to my stereo in the kitchen now doesn't work when the iMac is connected to the MiFi network. When I connect to my current Sky Wi-Fi router everything works fine so I am after any help as to how I can go about making the Home Sharing and Airport express work through my MiFi network and iPhone hotspot sharing.
