No, if you see no 5GHz information with 'iw list' then it means your cards do not support 5 GHz. Its a physical limitation of the actual hardware. To support 5 GHz your card would need a 5 GHz radio, and it simply does not come with one. For your Atheros card specifically the output shows a AR2122 RF, this is a 2.4 GHz radio only.
