I just bought a new ipad Air (1), and for some reason, I keep having wifi issues. Its intermittent, but at times I can't see DL speeds over .5 MBps. Not sure if this was a known issue or if anyone else has experienced it, but it ticks me off when I am streaming something to my ipad and I am literally 10 ft away from my computer and wifi router. I checked my wifi on my iPhone 5S and it gets 15-25 MBps, and I found if I connect back and forth to another network and back on... that I get better signal for a little while, but then it tanks again. Is it a know iOS 8 issue?
