Try using a static IP address. The following should work:
IP: 192.168.0.75
Subnet mask: 255.255.255.0
Default gateway: this will be the IP of the LAN interface on your router/ modem, usually something like 192.168.0.1 or 192.168.1.254, etc
Primary DNS: 8.8.8.8
Secondary DNS: 8.8.4.4
How this helps.
