Hardware info: D-link DIR-880L HW:A1 FW:1.05WW (actually applied 1.05.B2 already).
I've setup my 880L to act like a wireless access point, but it reports that the internet connection needs repair. This appears to be a bug, since wireless devices connected to the 880L are correctly getting an IP address and can connect to the Internet.
I setup the 880L in router mode, but turned off DHCP since the IP addresses are coming from my main router (ATT Gigapower NVG599). I tried bridge mode but this turns off all wireless configurations (I can't change the wifi network name(s)). The 880's IP address is reserved using the 880's mac address in the NVG599.
Devices are able to connect correctly, and devices show up connected. You can see in the pic below that 16 devices are connected wirelessly to the 880L.
