Info

Environment: Ubuntu 10.04 Lucid Lynx

Advantage of Using Network Manager as opposed to wpa_supplicant:

Network Manager supports the latest wireless advanced encryption method WPA2 AES. To date, the wpa_supplicant manual does not include WPA2 AES as a supported feature.

Network Manager Wireless Setup:

1. Right-click network icon in system tray.
2. Select Edit Connections...
3. At Wired tab, if you show a connection there, hit Edit and unselect Connect Automatically, and hit Apply.
4. Open Wireless tab.
5. Put check in box Connect automatically at top and Available to all users at bottom.
6. At Wireless tab, hit Add.
7. Enter SSID: name of your router, Mode: Infrastructure, BSSID: (optional - can be left blank), MAC: (optional - can be left blank), MTU: automatic. (Note: You can copy these optionals from wired connection if you have one.)
8. At IPv4 Settings tab, Method: Automatic (DHCP), leave the rest blank.
9. At IPv6 Settings tab, Method: Ignore.
10. At Wireless Security tab, Security: choose method and enter your password.
11. Hit Apply to save all settings.
12. Restart your computer:
13. If network icon in system tray shows a red x and "no network connection", ignore it.
14. Right click network icon, choose Edit Connections...
15. At Wireless tab, hit Edit, and check to see if the system has made a duplicate connection. It starts with auto. If so, delete it. Hit Apply to save, leaving your original wireless connection in place.

Network Manager Wireless Usage:

Every time you start or restart system, ignore the "no connection" icon status. You must get Network Manager to fetch the DHCP assignment from the router like this:

Open a terminal window. Type:

sudo dhclient

Authenticate your password and exit the terminal window.

OR this task may be automated at startup in Ubuntu 10.01 Lucid Lynx, by entering a simple little phrase in the rc.local file.

Open a root terminal and type:

gedit /etc/rc.local

Add the following phrase to rc.local without the # hash mark above the exit command:

/sbin/dhclient

Save the file and restart system. That's all there is to it.

Running the dhclient command is a must. Otherwise, Network Manager will search and search and never connect, even if all else is correctly configured.

As to configuring router, no problem. It's a go for WPA2 AES, N function by itself, and MAC address filtering.

Note: When starting your browser, be sure to bring it out of "Offline Mode". You may have to do this as often as you start or restart the browser. Hit File at top menu, uncheck "Offline Mode". Then go where you need to go. The gain in wireless security is more than worth this little nuisance.
