TCP/IP Weirdness

[Geekboy]

My TCP control panel window says I'm connected
via the Ethernet.
Configure: Using DHCP Server

Then automatically when I boot up the system reads my cable modem and automatically fills in the IP address and the Subnet, etc.

Now whenever I go into sleep mode and awake the system my IP address is blank and so is the Subnet and so on. I have to do a restart and everything is fine.

This never happened in the past when coming out of sleep mode.
I've trashed the TCP, System and Finder preferences files but nothing matters.

Whenever I go into sleep mode and come out of it all the address are gone and I can't connect to the internet.
I have to reboot everytime.
Anybody know what's going on?

thanks

Have you tried to turn off the Energy Saver and see if it maintains the IP scheme?

Are you spinning down the hard drive?

I don't mess with Energy Saver because I've had too many issues with it.

Theoretically, when your hard drive spins down, the machine has to "remember" where it physically was and what values were being used preceding its wakeup.

Not surprising that it wouldn't lose some of that sometimes.....

You may want to try to disable Energy Saver and putting it to sleep and see if that isolates the issue.

Hope that helps.

Chris,

Thanks for the info but that didn't help either.  I even put the Energy Saver control panel in the disabled folder and trashed the preferences and rebooted but still no good.

I put it in sleep mode and when I came out the fields in the TCP panel were blank again and had to reboot again.

Damn.........this is a strange one!

In the TCP control panel window click on "Options", Make sure that "Make TCP/IP Active" is checked and that "Load only when needed" is unchecked.
