Usually protected networks cause such problems. If you do not have security enabled, it means that your routers firmware is a problem, try updating it. Also make sure that if you are using MAC-filtering your ipone's MAC address is in the list. Some routers allow to create so called "Guest zone", where you can allow anybody to connect to router. You can allow this option and enable MAC filtering for the guest zone (not many routers support it).
