Also in regards to lack of display of static IP address...
I have a DIR-855, Hardware Version: A2, Firmware Version 1.12.
The Status|Wireless monitor displays the SSID, MAC Address, IP Address, Mode, Rate (Mbps), and Signal (%) of the wireless clients that are currently connected to the router.
For the DAP-1522 client that is connected to my router, the IP Address shows as "0.0.0.0", although that client has been configured for a static IP address.
