Q: Ethernet self-assigned 169 IP address 10.4.11
Suddenly and without warning my old G5 running Mac OS X 10.4.11 lost connectivity to the internet. I booted one morning and saw the dreaded 169 IP in the Network tab of System Preferences. Oddly enough when I boot from HARDDRIVE2 (same OS) in the same G5 everything's OK and I have internet. Booting from the main drive, HARDDRIVE1, yields nothing but 169 frustration.
Here's a list of what I've done to troubleshoot:
- Rebooted the modem (CenturyLink Actiontec C1000A)
- Rebooted the G5
- Trashed /Library/Preferences/SystemConfiguration folder and the two files within, NetworkInterfaces.plist and preferences.plist
- Determined that the ethernet cable is working properly
- Determined that all four ports on my modem are working properly
- Used Network Setup Assistant to obtain a 192 IP
The genius at my local Apple Store can't figure it out and Apple Tech Support won't talk to me because the OS is too old. You're my only hope, Obi-won.
PowerMac, Mac OS X (10.4.11), No Internet!
