Thursday, March 8th--I just upgraded to the new IOS 5.1 operating system on my new iPad2 and now I am unable to connect to the internet via Wi-Fi.  Has anyone else experienced this and how did you solve the problem?  It started when I tried to download the new iPhoto App and a message came on saying I needed to upgrade to the new 5.1 OS.  I did this and it took about 25 minutes to download it and install it.  Then when I went back to install the iPhoto App, it jammed halfway finished and said I needed an internet connection to finish the download.  I am writing this on my wireless laptop using the same source for Wi-Fi as the iPad has been using just fine.  Thanks for any help.  Cobraguy
