Connected but without TDE

Hello, By installing something like Ubuntu 14.04 I can easily have a wifi connection and even install some Trinity apps. This is by using the most recent repos (Raring, 13.04) as instructed in www.trinitydesktop.org/wiki/bin/view/Documentation/UbuntuBinaryInstallation. However, when the core TDE packages are selected (using Synaptic), they appear as broken - missing several dependencies. OTOH, if I try to use Ubuntu 13.04, with which I hope the Raring repos are compatible, then I can't get a wifi connection - my machine (Lenovo Thinkpad T440s) is too recent, and I have already gone thru the hassle of installing firmware, drivers, etc. to no avail. It's the same problem with Exe Gnu/Linux or a live CD Image for Ubuntu with Trinity preinstalled. Any ideas? For now I can use Windows or a distro without TDE. Also I think of selling the Thinkpad and using a less demanding (and expensive) machine. Robert
