Hello,
My Lubuntu installation has been able to connect to a network secured
with WPA2 and to another with WEP.  My TDE installation, from the
recent Exegnu live CD, can connect to the same WPA2 network but not to
the WEP one - the authentication fails.  Right now the WEP network is
the only one available to me, and I hope to be able to use it to
upgrade TDE.   Does the following info suggest anything?

$ sudo lspci -vv | grep Wireless

  Subsystem: Intel Corporation Dual Band Wireless-AC 7260
