I have a long list of DNS's that I've tried, none better than the other. Making these DNSs primary on the Mac fails to solve the frequent internet failures. I've tried over 15 DNS's, including the AT&T DNSs and none are any better than each other, It's the changing of the DNS several times, that usually brings the Mac to all green for a while.

Then I triedwireless, and wireless usually holds up a few minutes longer than ethernet, before the inevitable ISP, Internet and Server control panel indicators become yellow or red and I cannot ping out.Ĭhanging the Cat port on the Mac made no difference. Sometimes I change it to DHCP but results are usually fail. Network Radar tells me that my static IP choices are notin collision with something else. I have to do this about 3-4 times trying various DNS's and static IPs. Reboot or Physically disconnect ethernet from Mac, wait 10 minutes, reconnect, status returns to normal.Ĭhange 4th octet AND DNS to something else What I have to do, about every 10-15 minutes. Nearby (Ethernet) windoze box is always up. Static IP is primary, although I tried DHCP. Connection will not return until I do something. ISP, Internet, and Server becomes either yellow or red, and the Mac won't ping out.
