Thank you, but you grossly underestimate my ignorance :-(

First, I have no router. Well, not quite, for there's a router with my
wifi modem connected to my desktop, but I'm not connected to it. I've
picked a local AP (using wifi-radar) to configure. I assumed that no
router would be involved.

   # wifi-radar
   [I selected an AP to configure]
   Mode: Managed
   Channel: auto
   Key: [ what key?]
   Security: open
   
   No WPA
   Automatic network configuration (DHCP)
   Connection commands:
      Before: [leave blank?]
      After: [leave blank?]

  I click "Connect".

Then # iwconfig: 
    ...
    wmaster0: unknown hardware address type 801
    ...
    DHCP discover on wlan0 to 255.255.255.255 port 67 interval 4
    ...

   # ifconfig wlan0 up

   # ifconfig
   ...
   wmaster0 no wireless extensions
   wlan0  ...
   	  [No "UP"]
	  Link quality=70/100
	  Rx invalid nwdid:0 ...
	  ...


If I were using a router, what would be its password? With a desktop
machine, I have a modem router, but don't believe I set any password
for it .

How would I know if I  got a "DHCP reply" The ifconfig wlan0 command
above did not offer any inet address line, and so should I assume I've
got no DHCP reply?

I assume that without WEP, no password is involved, and in the
wifi-radar dialog above, and with "No WPA", I assume I could leave the
Key text area empty.

Should iwconfig report "no wireless extensions"?

Should I aim for there be a line in # ifconfig for wlan0 saying "UP"
and reporting an inet address?
