Anyone else out there use a closed network with MAC address filtering on their Time Capsule and have an iPhone 3GS connected to it? I added my iPhone's MAC address to the list so it can connect but it won't. I've tried changing the channel that my WiFi broadcasts, I've tried changing the WiFi to 802.11n - 2.4ghz, and opening up the network but no luck. I don't mind so much about allowing people to see my network but i'd really want to keep the MAC address filtering on. Any thoughts on why it won't connect? Everything else does with no problem - my Mac Pro, 2 MacBook Pros, and 2 Apple TVs. Why not the iPhone?
