Hi All, I am considering buying the new Aiport Extreme base station and had a question. I currently have a "g" broadband router/modem combo from Linksys. Two questions: 1) If I update to the new "n" Base Station, what will my speed increase really be? Will I notice a speed boost or does the broadband speed just look sexy on a speed test? 2) How can I check my current broadband speed? Is there a website I can go to to check the speed? Thanks to all!!!
