Hi, my impression from various web sites is that the Intel WiFi device in my Lenovo T400s laptop has support for the 5 GHz band channels. However, it seems to never associate with any access points using such channels. It always ends up using some of the 2.4 GHz channels instead, or not being able to associate with any access point at all.
Just FYI: There are versions of the T400 that do not have 5GHz. You need to check the exact chip ID. -- Ragge
