Readers Digest Version - Great product, but performance is 10 - 15% less than my original ABES. Ok, I had a an ABES that was running my whole wireless network. It lives in the basement and give me great coverage and speed on both the 1st and second story. I wanted to separate my G devices and setup a dedicated N for my Macs. Got a Time Capsule yesterday and tested it all different kinds of ways. Now, I really like the Time Capsule but found it's performance is not as good as my original ABES. I have no trouble connecting with the Time Capsule anywhere in my house but the strength and through-put is about 10 - 15% less when I'm on the 2nd floor. I moved it up to the first floor and this works fine for my house now. The Time Capsule on the 1st floor gives me the same signal I get from my original ABES in the basement.
