The university I work at uses its DHCP servers to update a dynamic DNS server when you connect to their wireless network. Sometimes the DNS update gets lost in the shuffle, and you wind up with an IP address but no DNS entry. The solution to the problem is to release your DHCP address and get a new one -- but the Network control panel in Panther only has a "DHCP renew" button (not the same as "release").
I found
a message on the web that describes one way around this:
- Open the network icon in System Preferences.
- Select a new location and call it "None"
- Turn off all selected ports. (Show: Network Port Configurations, uncheck all)
- Select Apply now.... your done.
Now every time you select location "None," a DHCP release packet will be sent to all active network interfaces and it won't ask for a new one. To get a new DHCP address, just set your location back to "Wireless" or whatever it was before.
