Yún - no connection

Good day!

I have the Arduino Yún, which I tried to reflash linino. Now the Board turns on but the computer (windows 8) does not form a connection with her. When connecting to the LAN on the motherboard led is on the connection status, but the list of connected devices on the router in the DHCP table no. I have a programmer for ISP, but I don't know how to flash it . Prompt it is possible as that to revive the device.

Thank you!
