It's probably like 4 years old (I have this one - http://www.ecobinary.com/ecart/images/airportextbase.jpg). Are the square ones any faster/stronger? I notice that when my laptop is right next to my basestation, I still don't get the full signal bars, I'm always one bar short. Thinking about getting the new basestation or possibly throwing an antennae booster on my current one. Thoughts? Thanks.
