we received a few of these tablets for christmas ... on one of them, the wifi button is grey and completely disabled. you cant click it. you cant swipe it to turn on the wifi. you cant do anything. i've done three hard resets and still nothing. no change whatsoever. i've been trying to contact the company for three weeks. they won't help at all. they originally said they were sending me a box to send me a new crappy one but that was three weeks ago and haven't heard anything since. (wrote them five emails and have called numerous times to just be hung up on) anyways, i thought i'd try to solve it on my own. these things aren't usable at all without a wifi connection. i have another of the exact same model and it works fine. two computers, lots of tvs and other devices all running from our wifi as well. it's not our router ...it's simply this tablet. just won't let you turn the wifi on. any ideas?
