I always have problems making my Internet work, but this is by far the weirdest thing I've seen. I'm writing on a PB right now, which is in the same network as my Mini. This computer and a PC are connected, but my Mini is not. I've not changed any options, but I can tell you what is on the PB and what is the configuration on the Mini. These are the preferences in the one that is working (PB): Configure IPv4: Using DHCP IP Address: 192.168.1.100 Subnet Mask: 255.255.255.0 Router: 192.168.1.1 Everything else in the TCP/IP section is empty, except the long IPv6 Address Now, this is the configuration of the Mac Mini (the on that is not working): Configure IPv4: Using DHCP IP Address: 169.254.173.205 Subnet Mask: 255.255.0.0 Router: Empty... weird Again, everything else is empty except IPv6. I'm using a linksys base station, and everything used to work perfectly until yesterday, and I haven't changed anything. Help please... many thanks in advance.
