    I just bought TL-WN781ND (WIFI card)

    I noticed it didn't work when my GTX 760 was installed on the x16 slot
    I moved my video card to the x4 slot and all of the sudden the WiFi card started working !

    this is my BO manual http://download.gigabyte.asia/FileList/Manual/mb_manual_ga-p55a-ud3_v2.0_e.pdf
    I've tried reading but I didn't find anything about this

    can't I use my card on the x16 slot and make this WiFi card work ?

    is this a limitation due to my motherboard or what ?
    is there anything I need to pay attention to when buying a new motherboard ?
    because I'm going to buy ASUS PRIME Z370 for my new PC, will I face the same problem when trying to install a wifi card with the video card on x16 slot ????

    Q1 - Not seeing any reason why it would not work, other than maybe its not fully seated.
    But there is nothing wrong with using it in the x4 slot

    Q2 -
    Should be ok
