Hello all! I have a MacBook 13,4" (late'08). It's so amazing! But I have a problem: When I connect the MacBook to a router with a cable, it doesn't get an IP from the DHCP-server. When I set the correct IP manually, it doesn't work either. The connection seems to be up, but when I try to ping the router, it says: Code: macbook-van-guido:~ Guido$ ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1): 56 data bytes ping: sendto: Host is down ping: sendto: Host is down ping: sendto: Host is down ping: sendto: Host is down ^C --- 192.168.1.1 ping statistics --- 4 packets transmitted, 0 packets received, 100% packet loss When I connect using Airport, it works fine. The router is OK, when I connect from another (non-mac) laptop using LAN, it works fine. I allready tried another router, other cables... But with no success. I Googled for hours and still can't find the solution. Could someone help me please? Thanks so much!!
