I cannot get my Ipad2 to connect to the internet. I reboot my router and ipad2 several times and is still does not work. I need information on how do setup a new Wi-Fi connection. What does "forget this network" do. IP Address/Subnet Mask/Router/DNS/Search Domains/Client ID/Renew Lease/HTTP Proxy/Off/Manual/Auto - do I need to enter the information manually? Thank you.
