WiFi dual band (or only 5GHz)

[shug]

Hi all,
I'll have to use my A20 boards in an awful environment with lots of WiFi traffic (2.4 GHz). So I'll probably switch to 5 GHz to be get less interference. Do you know an existing module or an USB stick working well with that board and Linux (Debian or Ubuntu)?
Thanks !

Hi, did you find s solution for 5GHz in the meantime? I try to get a RTL8812AU https://wikidevi.com/wiki/Realtek#ac_2 adapter working. But the RTL8812AU driver source does not compile with allwinner kernel

Maybe this version works for you https://github.com/gnab/rtl8812au

MakeFile:
CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_ARM_SUNxI = y

Hi Gerrit,

thank's for the hint.

But the version from gnab has same compile error:

CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_ARM_SUNxI = y
are set in Makefile

UPDATE:
after some adaptations it is now compiling and 8812au.ko was loadable via insmod. Will post patch later. But now i have to understand how allwinner scripts in android handle wlan with a specific module

Ok, rtl8812au working,

here some adaptations to get https://github.com/gnab/rtl8812au compile with allwinner kernel:
