IF you IP address is 0.0.0.0
this mean the machine is not getting IP address from the internet router,
because the WiFi is not set to give IP addresses for example...
ipconfig /all - the other pcs.
see what ip addres they have.. and make your pc same network ID
lets say 192.168.0.2 is on of the other pc
set Static IP to your net card, to 192.168.0.15 / 255.255.255.0 / router . ip. address .
make sure for internet you set the ipaddress of the router to your ROUTER in the network card configuration window...
Also I had this problem beffore, where a long underground cable was
eaten from some peredator with 2 teeths.
the cable las not cut , but the isolation was off and the receve cable was
touching the transmit... the you get 0.0.0.0 and no packets goes up or down..
