Router like repeater?

Hi. I've a Dlink DI-624 router WiFi.

The LAN section of this router is K.O. The router is still accessible via WiFi and allow the WiFi client flow.

There is no route from WiFi to LAN or vice-versa.

I would use this router like a repeater or bridge but the firmware doesn't allow to works in other way: only router. No client, No bridge, No repeater...

There's any way to enable the repeater/bridge function on this router? I repeat; the HTTP interface it's accessible via WiFi... I think the Telnet port, too.

Thanks!
