Here are the facts: -wireless icon not showing, in wireless settings it shows generally as connected, sometimes loses connection. This is my home connection, where it has never had a problem before. -internet on phone doesn't work when on wireless only. 3G works o.k. -I cannot ping other computers on network from phone (using a net utility app) -I can ping the phone, or at least the phone's ip address. I was thinking a duplicate ip address on the network might be a problem, but can't find another device with that ip address. IP address, net mask, router, consistent with network settings. -tried a hard reset by pressing both sleep and home buttons. No joy. -can't seem to change the phone's ip address maually (it seems to be set on static ip). I enter a new value but when I press return it changes to the old ip address. -ios7, iphone 4 Thanks!
