I use static IP adresses.
When changing the IP of a network interface (eth0 or wlan0) the settings are saved to the network connections but when running
ifconfig or looking at Network Settings, either connections retain the old IP address.
I have tried restarting the networking service, the computers (yes, this occurs on more than one) and even reinstalling the OS.
PLEASE can somebody help me. I'm losing out on so much work this past week just trying to get Ubuntu 12.04 working like a normal OS.
Using the command
sudo ip addr add 192.168.0.1/24 dev eth0 SOMETIMES works... the command switches the interface off, then when re-enabling it the IP reverts again. AAARGH!
