It sounds like there is some bad interaction between your Mac's DHCP client and your router's DHCP server since your upgrade. If your ISP already knows about it, presumably they already know about it.
Do you have control over the router? If it has firmware, you should try to locate the latest version, and upgrade it. If the router is crippled by design because your ISP has control over it, my recommendation would be to buy your own router. You could try setting your IP address manually. In System Preferences, Network, you select your interface, then choose to configure IP manually; if it's not on the main screen, press Advanced and it's there on the TCP/IP tab. You've got to use an IP address and subnet mask compatible with your other devices; pick an IP not likely to be used, like near the end of your range. You could use Google DNS (8.8.8.8, 8.8.4.4) until you learn the addresses of other servers of your ISP, if desired. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
