Please explain the error in this screenshot

DHCP Setting:

This screenshot was taken after powering off the old comp hence he server interface is shown as the wireless card - it becomes 192.168.0.1 when I connect wires and power up the old laptop to boot via PXE.

My scenario is simple. An old laptop and a new laptop . A cross over cable ( that I myself made from CAT 6 cable by cutting it and connecting 4 wires as mentioned in some doc). The new laptop ( tftp server ) has a Wirelss Card ( with which I am browsing and writing this ) . And the cable is connected between laptops .
