Ubuntu
software-center package

where is network manager

Asked by Mark Marsh

 I am new to Linux and need to set up wireless connections (which are available and operating under Windows 7).
I have installed Ubuntu 10.10 netbook on my new Samsung N220 Plus netbook as a 2nd Operating System.
I can see applications in the 'Ubuntu Software Centre' list and 'Network Manager' is noted as installed but I cannot find it through the 'Applications' icon under any of the categories. There are several other applications which are also noted as installed but are similarly not found.
Can you you please help me to find these.

Look at the top of the screen, next to the clock and the volume icon, there should be an icon like two arrows or an antenna.

If its not there, press ALT+F2 and run:

nm-applet

It should then appear

If you are tiold it's already running then run:

killall nm-applet

then try again

Currently connected by wire and can see up/down arrows which give options 'auto eth0, Disconnect and VPN connections.
Without wire connection I get the antenna symbol and the VPN connections option.
Should I be seeing the Network Manager when I open Applications and select System?

To add a wireless connection right click that icon and choose "Edit connections..."
But if you have a working wireless card you should have those autodetected. Maybe you need to install a wifi driver.
If that is the case try this:
- Connect to internet using a wired connection.
- go to System -> Administration -> additional drivers (or something like that, the icon is green)

There it might suggest some wifi driver you might be missing.

If that does not help, you will have to tell us what wifi card you have or the exact notebook model.

The 'Edit Connections' option shows 'auto eth0' under the wired tab but nothing under the wireless tab.
The netbook is Samsung Code: NP-N220-JP02UK and the Ubuntu version I loaded from the Ubuntu Netbook site.

I appreciate the help you are giving.

You have to get the wifi card working first. This procedure

should work. The thing is the card only supports windows, so you have to use the windows drivers in ubuntu, which is a bit tricky, but works most of the time.

The tool referenced there in the article I linked is ndisgtk, which you can install from software centre while connected with a wire to Internet. You may need to install other packages, too. Follow the instructions.

Excellent, Thanks Frederico.
For reference:
1. I installed Windows Wireless Drivers from Ubuntu Sofware Centre (after search for 'ndis')
2. Activated the Driver (noted this was Broadcom STA proprietary wireless driver)
3. Noted right click on antenna symbol has 'enable wireless' checked and left click shows wireless networks available. Tested OK.
