I have an ipad 1 and I'm having issues with the Wi-Fi. I was using it at my house with no problems until I went on vacation and came back. Now that Im back home and I try to use safari, it says it is not connected to the internet. It it showing full signal in the upper left corner. When I check the Wi-Fi settings, my router pops up, but it never connects. It keeps working and never puts a check by my router name. What gives??
