I have a Dlink wireless modem, and a Hawking 300N range extender for the far end of the house away from the Dlink. The ipad works fine on the Dlink wireless. But when I'm at the end of the house that requires connecting to the Hawking extender, I have problems. The ipad says I am connected to the extender, but when I go to open a web page it says it is not available because I'm not connected to internet. The range extender works fine with my Lenovo think pad, so it does work. Visiting friends have the same problems with their iphones. Any suggestions?
