I disagree! Wireless works fine for us. We are a one provider office. A main desktop with another wired desktop, and three laptops they are wireless since two are being moved around all the time. I never experience any slowness at all. I think her problem is the number of providers!
AC is great for a solo office, but once the # of provider exceeds 5, you will have some problems. That's also what I heard from my biller who has a lot of customers using AC.
