Guys I posted this question in another forum a few days ago and had no luck. I'll try again. I have an airport network that shares my internet and HDD wirelessly with a mini and MBP. The MBP works fine until the mini joins the network. As soon as the mini is on, the MBP can no longer access the internet or HDD but remains connected to the network. I have tried reseting and restarting in various ways. Have even reserved MAC address for both. Am using 'share a single IP address'. Please please help.
