Yes, network-manager is the applet I mentioned. When I select info, it
shows DHCP (IIRC), but most other figures are 0.0.0.0

It is. I've enabled Roaming. Before this, I didn't see any
configuration options on the network-manager applet.

It's every time I select the wireless network. I've never been asked
for a master password - I'm still using Feisty on this machine,
planning to upgrade v. soon.

I haven't really tried rebooting/logging in without changing at least
one setting, and every time I've had to re-select the appropriate
wireless network.

ifconfig wlan0

no IP address. When I connect to the wireless network and enter the
WPA key, the NO_CARRIER disappears from the ifconfig output.

route -n

default gateway is correct, but on device eth0 instead of wlan0.
Trying to ping the router gives host (or maybe network, not sure)
unreachable.


Hwyl,
Neil.
