Husband and I both have iPad2s. Can't get a lot of use out of them as they will not load mail, and FaceTime will not work. These both worked at the Apple store when we bought them and also both work when we take our iPads out of our home Wi-Fi range (friends homes, restaurants, etc). Strangely, our home Wi-Fi does work WONDERFULLY on the iPads.....we use Safari, play WWF, download from the App Store, etc. Weird - right? These are the only two apps we're having problems with, and the problems only occur on our home wi-fi. So, I naturally assume my Wi-Fi is blocking these apps and make plans to call Comcast (I live in Sarasota FL). Did some google searching and thinking probably the DNS would need to be changed, but I'm not the most technically savvy person ever. I did add 184.108.40.206, 220.127.116.11 and 18.104.22.168 but that didn't help so I deleted them. I'm a procrastinator and never called Comcast and then..... Just today I received my iPhone 4s and last week my husband got his iPhone 4s. No problem whatsoever using FaceTime over Wi-Fi. NONE! Mail and FaceTime work GREAT over Wi-Fi! Ever heard of this? Any solution? Don't know who to call here.....clearly my router/modem is working because my other apps are working on the iPad and even these apps are working on the 4s. Never seen something so strange!
