Hi Toan,

I received some more funding on the kickstarter campaign which will
allow me to add support for the external PA and external LNA stuff
which will bring our GPL'ed driver to the same level of hardware
support of the vendor's driver.
In order to do that it'd be great if you can provide some help:
Please flash your router to OpenWrt or LEDE and enter a console via
SSH. Then see which flash partition holds the wifi eeprom:
cat /proc/mtd
There is supposed to be a 'factory' partition, e.g. /dev/mtd2 or
something like that. Dump that partition to /tmp
dd if=/dev/mtd2 of=/tmp/factory.bin
Then logout and copy that file to your workstation:
scp root at 192.168.1.1:/tmp/factory.bin .
(assuming the router has the IP 192.168.1.1)
Then send that file (factory.bin) to me via email, so I can analyze
it and see how we can auto-detect those features present on your
device.

I know this is some effort (flashing OpenWrt/LEDE and then reverting
to the factory firmware, loosing your configuration on the way and all
that) but I would be a great help and most likely improve the bad wifi
signal situation on OpenWrt/LEDE within the next days.


Cheers


Daniel
