When I first unboxed my iPad 2 several months ago, connection to internet was a breeze = Verizon DSL. This weekend I stayed out of the state for a few days and was unsuccessful in my efforts to connect to my sister's network - Roadrunner with Time Warner. (I've been using my laptop there for years with no trouble.) Upon returning home to PA, I am now unable to connect to my network! My network's name comes right up, but does not give me any opportunity to type my security key... Thanks for any help you can give me.
