Wifi connection problem on new ThinkPad

Hello, On a new Lenovo ThinkPad T440S I installed Trinity from exegnulinux_4.2.iso dated 24-Jul-2013. This is in addition to a preinstalled Windows 7 Professional. Running wicd does not detect any wireless networks, however, wicd in Trinity in my older laptop does detect them. And Windows in the ThinkPad also detects the networks, so wireless must be enabled. AND wicd doesn't even see a wired network when connected with a LAN cable. Do I need to configure wicd? Or install from a newer image such as exegnu_wheezy_r14_26032014.iso? Or install (L|X)Ubuntu and set up Trinity on top of that? Robert
