         Hello Sir

         I am writing this request to ask for your aid, we have been
         tryng to get
         ubuntu 14.10 to run on an ASUS T100TA tablet and we are having
         wifi issues

         I am appealing to you and to ask for your help as i have been
         trying for
         weeks to get this wifi working stable, i have been trying to
         modify the
         NVRAM file to get a stable connection so we can have decent working
         internet on this tablet to enjoy the Linux experience. right now
         currently we can download in the range of 600 bytes/sec to maybe
         10kb/sec

         We are unable to connect with the current NVRAM file provided
         from the
         NVRAM file unless we put our current MAC address for our wifi
         card in
         the brcmfmac43241b4-sdio.txt

         and once we do that we are able to connect but we get frequent
         disconnects and very very slow download rates...

         I have pulled the NVRAM from the efivars in 
sys/firmware/efivars and
         have attached it for you is there perhaps an updated file that will
         work, or would you be able to help us and create a new or provide a
         current NVRAM File?

         Also the firmware that is provided for us is dated july 17th 
2013 is
         there an updated linux firmware that we can use for this device 
that
         perhaps would have an updated NVRAM file to go with it?

         I have attached the firmware that is provided for us as well for
         your
         reference

         I am sure you are a busy person and we in the linux community
         would love
         to be rid of windows and enjoy the linux experience, could you,
         would
         you lend us your aid?


     Hi Brian,

     Sure I can try to be somewhat helpful. I am currently on vacation
     and rain is pouring down in buckets.

     The nvram that is in EFI should be the perfect fit for the device.
     Maybe you can provide some more background info. Are you using stock
     ubuntu kernel. What kernel version is running? Can you boot the
     kernel with 'debug ignore_loglevel' parameters, load the brcmfmac
     driver with 'debug=0xd416', and send me the full kernel log.

     Regards,
     Arend
