Wifi dont work. i try kmod-b43, kmod-brcmsmac, kmod-brcm-wl drivers.

Nice to know it's working, except for WiFi. Thanks for testing!

b43 support for WiFi on SoC 0x5357 is next on my list, but it will take some time anyway.

Let me know if I can help

This WLAN LED being controlled by 2 GPIOs is a bit confusing neutral How exactly does it work? Do you need to set only one GPIO to "1"? What happens if you set GPIO 0 and GPIO 1, both to 1?

I also don't understand why your router is not detected as "Asus RT-N15U" anymore. Did you do anything nasty to your NVRAM? Could you provide output of "nvram show"?

The discussion might have continued from here.
