iPhone 4 defaulting to 3g over wifi
I have and iPhone 4 with iOS 4.1 that is defaulting to 3G over wifi. I have "reset network settings" from the settings > general > reset tab and it is still not working.
I am using a linksys e1000 router and it lists my iPhone's mac address as 192.168.1.121 (a random assignment from the dhcp client table from the router administration browser). The iPhone on the other hand is displaying a 169 address suggesting that it isn't connecting.
This has only started within the last couple of days, but just for reference, the wifi is "mixed" WPA2 Personal. i don't recall what the definition of mixed is for the e1000 router, but it works with older g-devices, and this iphone has connected before without a problem. (another iphone 4 with iOS 4.1 in the house is connecting just fine still).
Any ideas? Thanks.
all of them, iOS 4
