For those of you that have the wifi connection go down but your wired devices still get internet data fine you could try this.
Try locking the channel selection for g and n from auto to some specific channel.
With just an iPhone I was working with a time capsule just fine for months. Now I have a lion laptop in my house as well and it started having wifi problems. Even weirder it was causing my iPhone to be kicked off also, something that device wasn't doing before bringing a mac into the house. I tried some general stuff I found on the forums which didn't really help but given two devices either couldn't get data or just couldn't even see the SSID when it was down I blamed it on the time capsule. The one thing I changed which made a real difference three days ago was locking down both the g and the n from auto configure channel to just selecting a channel number and locking it there. Not a problem sense then.
I live in a condo and I can see nineteen SSID names on the macbook and ten on the iPhone, it is a little crowded. I don't know if the WAP was hopping around or catching interference or something but this is a worked for me thing.
