iPad mini intermittent wifi dhcp client failure.
Got UK 16Gb iPad mini WiFi IOS 6.01 13 days ago. Have noticed intermittent browsing hangups on my D-Link DSL-2780. No problems observed for Macbook (Mountain Lion), MacBook Pro Santa Rosa (Snow leopard), iPhone 3G cellular data OFF, Nokia E61.
Today at a friend's house with Zyxel P660HW router the iPad mini lost WiFi , going into settings saw his ssid showing good signal but a 169 IP assignment ie no address assigned by DHCP - tried renew lease but no effect. iPhone 3, E61, and iMac (Snow leopard) all happy on same ssid. Then created local hotspot E61 Joiku - iPad sat there whirling no connection on Zyxel ssid, showing strong signal on E61. I prodded the E61 bar and it logged on to it working perfectly. Powering off and rebooting Zyxel router got the iPad onto it working fine for a few minutes, then it hung again with a repeat of the scenario above.
This has to be buggy code on the iPad mini, possibly the DHCP client. Apple people please fix this.
There are also iPad mini Bluetooth issues, which I will post separately.
