I have a Mac Mini (late 2012) 2.3 i7 w 16 gig of ram that is seeing super slow wifi speeds. I've run several speed tests on a couple of other Windows PCs i have in my house connected wirelessly to the same router which are 5-7 times faster than on my mac. I'm seeing DL speeds on my Mini of only 5Mbits, where I'm getting 33Mbits on my Acer laptop, and 22 Mbits on my Dell Laptop (which is 6 years old) and is sitting right next to my Mac Mini. interestingly, I'm getting 10Mbits+ upload speeds on ALL three machines (the Mini included). I've tried shutting down the laptop which is in close proximity to the Mac Mini (incase it was causing interference) w no effect. I have read that USB 3.0 HDDs next to the machine can cause issue (which is crazy, but true), and i've made sure those are off... I've shut off and restarted my wifi adaptor - and it's still crazy slow... Any thoughts? Thanks!
