[Intrepid] Can't configure Wifi internet and ethernet static IP

[Shaun Crampton]

Binary package hint: network-manager-gnome

Just upgraded to Intrepid beta and found that the network manager no longer has the manual configuration option. Therefore there is no way to configure my network. I use WiFi for my internet connection and then use my ethernet NIC to host LTSP clients. As soon as a client boots up, network manager starts using the ethernet NIC for the internet connection and I lose connectivity (since the only thing connected to the ethernet is my LTSP clients).

I think the manual option should be reinstated since it's needed in a number of different situations.

You should be able to configure your network by right clicking on the nm-applet and selecting 'Edit Connections'

Thanks for your help, I think I now have it configured correctly. However, the new system seems like it needs some usability improvements:

  - It forced me to specify a gateway in the manual confiig even though there isn't one on the network attached to the interface (since this computer is an LTSP server with two NICs). I tried setting it to my IP, but that didn't work and it magically changed to 0.0.0.0 when I opened the dialog for a second time.
  - There is no help or example configuration to help.
  - There are a number of options that are not explained "Link local"; "Shared to other computers"; "DHCP Addresses only".
  - It's not clear what the system setting and connect automatically check boxes do. As a technical user I'm guessing that the former makes it a global configuration rather than tied to my user account. I'm not sure if the latter means "connect to the internet over this interface whenever it's available" or "bring this interface up at boot".
  - The routes dialog is also completely devoid of help or examples. Even as a technical user, I need a reminder of how to fill all those rather complicated fields in.

Unfortunately, the configuration doesn't seem to still work after a reboot. I can't seem to configure my Wifi connection to provide internet and for my ethernet connection to just have a manual IP address, but not to be used for internet access. How should I configure this?

I have the same problem to, network-manager is not saving the manual IP configuration after a reboot

Static IP settings disappearing after reboot is bug 259214.

The network mananger in version 8.10 is downright shambles. I can confirm the 'gateway bug', mentioned above, which is adding 0.0.0.0 as a gateway,automatically. But my problem is much worse.
I have two NICs, eth0 and eth1. One is local LAN and the other is the internet connection. When I try to manually config the eth1(local), I enter the correct network mask (255.255.255.0-- what else). When I save the configuration, the mask is changed to unexplainable 24 - thats right, 24. And they add 0.0.0.0 as gateway address, too. I have tried about 200 times, or so, every time I can find my network mask changed to 24. The tabulator key does not work, by the way. When I have entered the IP-address and use the tab key, I am taken out of the ip-address/mask/gateway line. I have to use the mouse to go to the mask box. There I have to get out by pressing the tab key, otherwise the OK box will not show up active, from its inactive state. The whole GUI is corrupt, as it seems to me.
I have also tried to edit /etc/network/interfaces, calling ifup in rc.local, and all the expensive stuff. When I reboot, I find out that my network manager has gone completely bananas.
I have had ubuntu 6.01 for years, and fedora 6 for years. No problems.I have always been able to ping them.
Since ubuntu 8.10 my network has gone bananas. Can anyone explain to me how I should proceed?
I mean, since the graphical tool is obviously corrupt, which other possibilities do exist?
How can I bypass the graphical networking tool? How come that the network tool is reading the correct info from the files and making shambles out of it?. Now I had to boot VISTA and submit this. F...it. By the way, referring to bug 278211, I also cannot understand the configuration options.

24 is the CIDR notation for 255.255.255.0, which is not an issue and I think is normal operation. As for the gateway route, if you could please open a terminal and run "route -n" and post the output of it.

Seems to be fixed in Jaunty. There is now a "Use this connection only for resources on this network" option in the routes dialog.
