At my work there are some wireless network access points. At my home there are some wireless network access points. The iPhone will latch on to open networks automatically. The networks at work say they are open (on the phone's wifi connection screen). The phone will say it has connected to the networks at work. However, when trying to access the internet after wifi is established, you get the familiar 'NO NETWORK FOUND' popup and nothing loads. The only difference I have noticed is captured by the following screens (not my actual device).
At home:
At work:
All things else equal, I have noticed the phone will not truly connect to 'open' networks when there are two digits (work) in the IP address as opposed to three (home)
Any ideas?
