My laptop MSi S12 has a RTL8723ae PCI card with Ubuntu 14.04 on board. It doesn't detect wi-fi networks.

I tried the answers from ubuntuforums and Wireless card Realtek RTL8723AE-BT is not recognized but make fails.

How can I fix this issue?

UPDATE:

1) Fail with "make" drivers is the same like here - Problem building an rtl8723 driver . And, in my case rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012.tar.gz gave me the same error (I suppose drivers have trouble with 3.13 kernel).

2) Wireles modules looks OK:

alex@gendalf:~$ lsmod | grep ^rtl 
rtl8723ae              76506  0 
rtl8723_common         22417  1 rtl8723ae
rtl_pci                26314  1 rtl8723ae
rtlwifi                52835  2 rtl_pci,rtl8723ae

3) A little bit more information

alex@gendalf:~$ iwconfig 
wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
          Power Management:off

lo        no wireless extensions.

eth0      no wireless extensions.

I've experienced much better performance with this network card following the advice from this user:

https://zach-adams.com/2014/06/fixing-rtl8723ae-driver-ubuntu-linux/

In short, two stages:

  1. Try installing the linux-firmware-nonfree drivers with this command:

    sudo apt-get install linux-firmware-nonfree

  2. Try installing the WICD network manager. For instructions for your version of Ubuntu, see https://help.ubuntu.com/community/WICD
