Thank you for your reply. Originally, my 2Wire router did not have a password but the iphone showed the padlock symbol next to it and asked for a password. That's why I set one up, but entering it in the iphone didn't solve the problem. However, I just now was able to connect via Wi-Fi using an Linksys router, presumably a neighbor's, although the signal was weak. I would like to be able to connect using my 2Wire router, but don't know how to access it. Maybe my ISP who provided the 2Wire router could help me.
