just wondering what the best wireless mode is for the 1st gen Time Capsule. Currently I have it on 802.11n (only 2.4 ghz). All of my devices are n compatible. There are a lot of other wireless networks around me. I was thinking maybe 5ghz only would be a better option but then I realized that the iphone 4 only did 2.4ghz. If i do 802.11n (abg compatible) will this use a mixture of 2.4 and 5ghz or am I stuck to 2.4 ghz with this as well? Thanks for any help. If you have any other settings tips I'd appreciate them!
