I use ubuntu netbook edition on a Samnsung N150. Used to work fine.

* But network manager does not appear at startup anymorw.
* Under preferences > I have the following enabled ...
nm-applet --sm-enable

Because this is ubuntu netbook edition I don't have the standard menu to access > system etc ....

What else can I try ???

Advance thanks,

A few safe checks to try before doing a full GNOME reset (as suggested). Missing Network Manager icon usually means the applet never started, the panel/indicator area crashed, or the service itself is stopped. The steps below try the least-destructive fixes first, then escalate.

Check whether the applet and service are running, try restarting them, and start the applet by hand so you can see any error messages:

pgrep -a nm-applet || ps aux | grep -i nm-applet
nmcli device status
sudo service network-manager restart        # works on older Ubuntu/Upstart systems
sudo systemctl restart NetworkManager       # works on systemd systems
nm-applet                                   # run in a terminal so you can read errors

If the applet starts manually but does not appear after login, look for a disabled autostart entry or an absent notification area. Inspect /etc/xdg/autostart and ~/.config/autostart for an nm-applet .desktop file (or a file that hides it). Also check logs for clues:

ls -l /etc/xdg/autostart ~/.config/autostart | grep -i nm
sudo grep -i nm-applet /var/log/syslog* 2>/dev/null
grep -i nm-applet ~/.xsession-errors 2>/dev/null
journalctl -b | grep -i NetworkManager   # if journalctl is available

If those checks show nothing or nm-applet crashes, try reinstalling the Network Manager packages and back up your desktop settings before any wholesale reset:

sudo apt-get update
sudo apt-get install --reinstall network-manager network-manager-gnome
tar czf ~/gnome-config-backup.tgz ~/.config ~/.gconf* ~/.gnome* 2>/dev/null || true

A full reset of GNOME/user dotfiles can fix the issue but is destructive and will lose panel/layout/custom settings, so keep a backup and use it only as a last resort.

Hi,
If the network manager icon is not appearing, but it has been, than it can be fixed using the following commands typed into a terminal:[just copy & paste the lines in green to a terminal :)]
(Change current directory to the home directory):
cd
(Backup in case anything goes wrong!):
mv .gnome .gnome-bak && mv .gnome2 .gnome2-bak && mv .gconf .gconf-bak && mv .gconfd .gconfd-bak && mv .metacity .metacity-bak
Remove the current config files:
rm -rv .gnome .gnome2 .gconf .gconfd .metacity
Now reboot your system(or just simply log out and log back in),when you are done with it you should have the default setup back!
