家里如果其他设备没有问题而只有iPad有问题，那么就不是reset 路由解决的。看看你在iPad网络设计里面有无proxy ，或者 DNS设置了openDNS

How do u remove OpenDNS from your IOS? Locate the Wi-Fi network to which you are connected on the Wi-Fi screen and tap the blue arrow to the right of that network. Tap the “DNS” setting under DHCP on the Wi-Fi network settings screen. Tap the “Backspace” key on the on-screen keyboard to remove the OpenDNS servers from the DNS field.
