I've searched for someone with a similar problem here and on the web and cant find anyone else with this problem. I have ATT wireless wifi set up and run 3 Macs and a Windows tablet on thet network with no problem. No lost connections, speed is outstanding. But, all 3 of the idevices that I use hang up during use - by hang up, I mean the blue progress bar in Safari stops midway and just stays till I get a time out message. All devices are cellular as well and the only way I can proceed in what I am doing is to turn off the wifi and let cellular take over. The cellular works just fine then. IPhone 6, iPad Air 1 and iPad Mini 2 all do the same exact thing, while all the computers run with no problem.. It cant be the hardware, and the wifi signal is great. Anyone with an idea of what is wrong? This has been happening forever, its not a new problem. i just use cellular on the idevices when at home only most of the time. Any suggestions are welcome.
