wahiggins3,
First, make sure you have the latest firmware installed for your D-Link. Many routers, and D-Link is not alone in this, don't always provide information via DHCP using the accepted standards for DHCP. Any updates that mention digital devices or gaming consoles usually address that issue.
Second, what security are you using on the router? Are you using MAC or hardware address filtering?
Personally when entering my password for the wireless network at my in-laws I had to slow down and remember that the letter that will be typed will pop up if you hold your finger on the screen. If it is incorrect you can slide your finger to the correct one, and then lift it off the screen.
Hope this helps,
