Here is my set up: main access point downstairs with linksys wireless router, upstairs I have an extender that is hooked up into my airport base station extreme. The airport then send the signal to my iMac which I am typing on now. I basically have strong wireless throughout the house. Will the MBA's airport work fine and get a fast and strong signal everywhere my iMac gets? I was just wondering because I read on here about the wireless of the MBA being weak? can someone please elaborate on the MBA's wireless capabilities interent wise? Thank you.
