D-Link DAP-1522 :: Devices Local Do Not Show On Network Map

This is the configuration I am running:Internet > Cable Modem > Netgear WNDR3700 Router ~~ DAP-1522 > Wired Windows 7 PC + Linux PC + Printer.The Windows 7 and Linus PC's do communicate well to the internet as do any laptops accessing the router wirelessly and any devices wired to the router. That is the good news.

The bad news is that any devices located after the DAP-1522, including the DAP-1522 do not show up on the network map of either the router or any of the wireless laptops. Neither does the Win 7 PC connected through the DAP-1522 show any networked devices, whether through the DAP-1522 or not, even though network discovery is turned on.

Right now the DAP-1522 is set up to function as a bridge and is in "Static IP" mode. I tried changing it to DHCP, but the DAP-1522 will not allow saving that setting, even though it will allow changing it. It just reverts back to "Static IP". The firmware version is 1.31, and the firmware update went well after a workable logon to the admin page was discovered. Also the one-button (WPS) set-up to the router worked as far as allowing an internet connection.

What needs to change to allow all the devices to show up on the network maps and maintain internet access? Ultimately, I would like to stabilize the IP's of the major components of the network to make troubleshooting easier. But to do that the devices need to show up on the network maps, particularly of the router, so they can be added to the IP reservation table by selection.
