    Very nice work.
    Just a quick question; is there a third wifi antenna available in XPS 15z?
    Asking because I would like to know whether I could upgrade this wifi card to a 450MHz one.

  2. Hlong

    I ‘ve just installed an intel wireless card 7260 ac on my xps 15z, updated all latest drivers from intel download center but it ‘s still not working now. In device manger both Intel wireless card and bluetooth show an Exclamation mark.

    how are the speeds with this card? Assuming you’ve got an AC router to test with.
