iPad Mini with LTE could not join wife at all, keep pooping up unable to join network. Sometime will need to wait 10 minutes or more to get wifi show up on the list.... This has happen to all iOS 7 iPads, but not in iPhone or iPod Touch. Wifi will keep connect if you put the iPad to sleep, but unable to connect to wifi randomly when you turn off and turn back on. All my other devices, including Nexus 4, BlackBerry PlayBook, Macs and Windows PC could connect to wifi with no problem. 1. Tried rest network setting, still same error. 2. Unless I reboot my router, it will not connect, Since my 3G network is unlimited bandwidth, the carrier choose to disable some app accessing networks, such as VoIP, email client and instant messaging... So it is extremely annoying without wifi at home. Notice for second picture, my network didn't show up at all. Sometime it will takes 19 minutes or more to find my network. His has only happens since beta 5, never before beta 5.
