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?

Ok, looks like no solution for this one. I've thought of 3 ways around it: - (using Lubuntu) manually fetch network-manager-tde and all its dependencies and install them in my TDE installation, in hopes of using it to make the connection. - try to find a wired connection or a network that uses WPA. - get the Ubuntu live CD, which looks more current than the Debian one that I installed from. Q: what is the effective difference between using the Debian and Ubuntu distros?

Off the top of my head Ubuntu ships with non-free firmware by default and allows insecure operations (such as using WEP--WEP is practically useless and provides no real protection) by default. Debian has a more privacy- and security-conscious stance, and does not ship non-free firmware by default among other restrictions.
Personally I prefer the Debian approach, but that is due to my years of experience with Linux and my preference to know of potential security problems. Most users (including myself when I was just getting started so long ago) instead find this frustrating and spend long hours with Google trying to figure out why things are not working. ;-)

Thanks. I'll look for a wired connection or WPA-secured network and have a go at the Debian version. Robert

I haven't been following the thread so apologies if I'm repeating stuff. As Tim says, firmware/security seem likely culprits. This link may help;
