Builtin rtl8723ae Realtek WLAN driver detect card but cannot set it up

Hello there,

I have been trying to make my new computer's wireless Realtek 8723AE card work under Linux over the two last days but it did not work though I tried a lot of things.

Brief

The rtl8723ae module is correctly started on boot and will recognize the wifi card as shown by dmesg and list it in availaible interfaces with lo and enp2s0 LAN card.

However I cannot set it up using either the `ip link set wlp1s0 up` (or `ifconfig wlp1s0 up`) ; doing so and running a `ip link show` after will still show it as `DOWN` and if we look in dmesg we can see a new line:

ADDRCONF(NETDEV_UP): wlp1s0: link is not ready

Due to this problem `wifi-menu` calls are unsuccessful because the card is not up. I bother if this is only an IPv6 error or if this is also meaning that the whole card is not ready, because I do not need IPv6 on WLAN networks so I can disable it if possible.

Tried hacks

• wicd will not perfom better as default system network tools.

• compiling the Realtek Linux modules from scratch and modprobing it does not help

• Other random module options settings like `ips=0` but no improvement

Some of these hack where also tried on Ubuntu, but I quickly installed Arch over it in order to have a better driver testing environment (and I was suspecting that the kernel was too old but same problem on Arch so…).

Thank you a lot for any feedback! The wifi card is perfectly working on Windows 8 dual boot with Realtek drivers so this is not an hardware issue.
