when computer boots you must press a key (at mine is F12) . You will see at down page something like "Press F12(or del or something else) for setup". When you press that key , BIOS configuration page will come up . Be careful there what to change. Just try to find something similar to "Usb Legacy" and if is disabled , you must enable it.
Something else . Did you try to change usb port of Usb wireless adaptop ? If not , try it.
