I have a 2010 MacBook Pro with OS X software. Last night I started having really slow wifi connectivity. I am not having this problem on my iPhone or AppleTV. As a matter of fact I am having to type this out on my iPhone right now. I am trying to run a speed test but that page had been trying to load for five minutes. I read a few other posts and tried switching DNS server but it didn't help. I really know nothing about this stuff. PLEASE HELP ME!
