[Ti] Internet connection drops between sessions

[John Griffin]

When I sleep my mac in the evening I also switch off my DW6000  
satellite modem. In the morning I switch the modem back on and when  
all LEDs are lit, I wake the computer. Invariably I have no Internet  
access on my Ethernet port. The Network Prefs pane shows that it is  
active and it also shows the correct connection addresses which are  
supplied by the ISP. But the dot in front of the Ethernet port is  
amber rather than green and it has the notation that the port is  
active but not connected to the Internet because it has an ’internal  
address' But I don’t see any internal address, just the IP address  
that it has acquired via Auto DHCP which is always correct. Hitting  
the renew button does nothing.

Can anyone tell me why it is acting this way?

I tend to run around trying this and that with no real idea of what I  
am doing, but which always eventually gets me connected and running  
again (unplug the cable, reboot computer, reboot modem, etc.)

I should also explain that whereas I used to have a wireless router  
system when I was actively employed (now retired), I have decided to  
bypass it and just hardwire a connection between my computer and the  
modem and simplify things.

Any help would be appreciated.
