Wireless not working in Lubuntu 12.10 : Ralink corp. RT2561/RT61 802.11g PCI

[Lars Noodén]

During the installation and after booting the installed system, Lubuntu
is not finding the wireless card or any local WLANs.  Ubiquity is
finding the device (Ralink corp. RT2561/RT61 802.11g PCI) but not any
network that I care to set up.

  $ iwconfig wlan0
  wlan0     IEEE 802.11bg  ESSID:off/any
            Mode:Managed  Access Point: Not-Associated   Tx-Power=off
            Retry  long limit:7   RTS thr:off   Fragment thr:off
            Power Management:off

I tried earlier with 12.04 [1] and had no luck either.  The wireless
does work, I did see it find a wireless network once before, but only once.

Regards,
