Do you get the same IP address from DHCP every time? My guess is yes, and your network has some kind of protection against rogue devices connecting to the network via static (unauthorized) IP. When the network switch/router sees an unauthorized IP, it drops the traffic. I have similar experience in my company's network.iAnathema wrote:Yep...
Then if I set the same static address that the Dhcp server gave to me(172.20.0.30), it's works!
