    Dear all Z83-4 users,

    By default, Broadcom has hidden some of the available Wi-Fi channels,
    by replacing the nvram file attached in this thread, it will unlock them and make them all available for use.

    To do so, download the attached 4356r6nvram,txt file,
    then put it to C:\Windows\System32\drivers

    Replace the file in the destination, restart the system, done.

    This will enable:
    2.4GHz channels: 1/2/3/4/5/6/7/8/9/10/11/12/13
    5GHz channels: 36/40/44/48/52/56/60/64/100/104/108/112/116/120/124/128/132/136/140/144/149/153/157/161/165

    It appears that you think a BIOS fixes everything! o_O
    It is a driver thing nothing to do with BIOS!

    I recently wiped my system as well. Every driver seems to have installed correctly except for the wireless broadcom driver. It wont install. I copied the nvram text file into windows system 32 drivers and restarted but it still wont install. I have been and continue to search the forum for how to install this driver but everything keeps pointing to this file being manually inserted....which i double checked, did do. Any help? Thanks.

    So I found out the problem. I read that you simply point device manager in the right direction to update and install the drivers. The wifi driver however kept failing even after moving the nvram text file. Turns out windows is stupid. It installed all the drivers fine, but the wireless driver is 1 too many files deep and cant read it. Pointing it to that last file fixed it. It always seems that when I finally give up and post for help..I find the fix minutes to hours later....lol

    Can you please explain what you mean by the last file? What file specifically did you update? I am having the same problem as well.

    When you open device manager and point it at the files, it finds them and installs them. The Wi-Fi driver requires that you navigate directly to the driver. It will not search the folder more than 1 file deep. I forget offhand the exact folder names but he is an example.
    Main drivers://main folder/drivers

    Wi-Fi driver: //main folder/drivers/Wi-Fi specific driver

    It seems device manager won't read more than the 1 level of folders deep. So you point it at the driver directly. The nvram text file also must be moved as stated. After this is all done restart computer.

    Put the "4345r6nvram.txt" NVRAM document under the folder C:\Windows\System32\drivers

    Then restart the computer to take effect.
