can't enable wireless networking after manual configuration.

[Gabriel]

Binary package hint: network-manager

It is not posible to enable wireless network again after do a manual configuration.
After a manual configuration, the only menu option in the NM applet is "manual configuration". Enable Wireless Networking is missing. There is no way to enable wireless again.

Relase: Hardy 8.04

network-manager 0.6.6-0ubuntu5
network-manager-gnome 0.6.6-0ubuntu3

I can confirm this on xubuntu and ubuntu 8.04. Or rather, if I configure a wireless network manually with encryption, I can't use nm-applet to choose wireless network. This however works if i configure an open network and set the wireless card in roaming mode. The wireless network is up and running, but I can't choose network if i have several, or switch between wireless card and eth0. Also, the nm-applet icon that should display link quality as a bargraph is only shown when using roaming mode, not if manually configured (encrypted/dhcp).

Where to proceed from here?

if you do manual configuration you dont use NM ... in 0.7 all thise manual configuration stuff isnt needed. so this is somewhat fixed in intrepid.

"Enable Wireless Networking is missing"

If you want the Enable Wireless checkbox back, look here:

In a nutshell, remove the following lines from /etc/network/interfaces

  auto eth1
  iface eth1 inet dhcp
  wireless-essid zzzzzzz
