Select the connection you wish to use, then click Properties.
Ensure Enable this connection is turned on.
If your ISP or network administrator has given you an IP address, set Configuration to Static IP address, then enter the address in the IP address field and click OK. Otherwise, set Configuration to DHCP and click OK.
To activate or deactivate network connections, select your connection, then click Activate/Deactivate.
There is nothing like Network (as mentioned in step 1), but Network Tools??
A quick googling and I found step-by-step instructions for installing ubuntu on your hardware.
It appears that earlier versions had trouble with the wireless driver. Are you trying to configure a wireless or wired network?
Finally I gave up my Ubuntu installation and formatted the entire system to reboot my Windows Vista! It's a pity that I was not able to have a dual boot with Ubuntu alongside Vista and do what all I have been doing on my Windows partition.
This is really strange, I have never seen a Linux installation not configure a wired NIC (wireless, yes). Or wait a minute. A while ago my daughter got a fresh-off-the-line ASUS motherboard with a very new wired NIC and neither Fedora nor Ubuntu would recognize it and we had to install an old NIC card in her rig to get it on the network. So I guess it is possible.
Now that you are back on Vista, go into Device Manager have it give you the specs (manufacturer, model, etc) for the NIC and google for Linux help with that NIC.
Also, its a little late now, but did you try opening a terminal and running "sudo ifconfig"? That would at least tell you which NICs it found, if any.
I've heard about a problem in the current version of the Linux kernel used in Ubuntu 8.10 (kernel 2.6.27-11): some wired network adapters don't work anymore because of a bug in the kernel. It has already been fixed and is planned for update 2.6.27-13 (I don't know when it will be available). Note that this does not happen with all network adapters, just a very few specific models.
But even if the problem is that particular bug, then it's strange that you don't see the Network item in the menu.
I've never had luck with getting Linux running on my machine. Earlier I had a Desktop PC and was a total fiasco when trying to get Fedora core 5 running and hooking it up to the internet. Now, the same happened when trying to get Ubuntu on my Lenovo R61.
If you want linux to work NOW, try using VMWare Player and download a pre-installed virtual appliance.
If you want to dual-boot, you've got to be really patient. We haven't scratched the surface as far as network troubleshooting is concerned.
And if you want to get angry, get angry at the hardware manufacturers who don't produce Linux drivers or publish specifications so drivers can be implemented easily. Linux, much like this here ranch, is maintained in large part by volunteers.
I'm using Xubuntu, which is very similar, but not the same as ubuntu.
There you will allways have the Network-applet shown as Icon in the menubar. It's symbolized by two screens, one behind the other. This should show up if an eth-chip is detected (and not switched off in bios), if a wifi is detected, or if a modem is detected. 3 chances.
On the page linux-on-laptops http://www.linux-on-laptops.com/ibm.html I find two different chips for the lenovo R61:
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN Network Connection (rev 61)
03:00.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
The command for linux is:
The command to start the network-manager-applet on xubuntu (8.04) is nm-applet , maybe it is the same for ubuntu.
