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

  • That older driver file is unlikely to compile on 14.04. In fact, the driver rtl8723ae is already included in 14.04. Is it not working as expected? What are your symptoms? Are there any clues in the message log? dmesg | grep rtl Thanks. – chili555 Jul 18 '14 at 20:14
