Need urge to fire up this RTL8723e WLAN interface on axioo RNE model. Using updated precise with 3.2.0-30 kernel the network manager cannot see this device. Here is the lsusb outputs :
{code}[[email protected] ~]# lsusb

And here is the lspci outputs :

For some minutes try to find the supported Relatek driver module for this wlan, but cannot find it everywhere, neither on their driver download page or any reply from email sent to realtek wlanfae. Found this tutorial and give it a go … and voila … its workin … host the source here in case anyone need it.
The driver compiling and installation is very easy,
1. Prepare the driver build environment and kernel header : {code}sudo apt-get install build-essential linux-headers-generic linux-headers-`uname -r`{/code}
2. Extract the downloaded driver source to some location, then cd into it.
3. Do make :

5. And finally load the driver module :
{code}modprobe rtl8723e{/code}
The driver will loaded succesfully and the network manager will automatically pick up the device and scan the available AP. (don’t forget to switch off the Radio Kill Switch with Fn + F11 in case is switched on)
If you’ve got error trying to modprobe rtl8723e, just like this :
{code}[[email protected] rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012]# modprobe rtl8723e
FATAL: Error inserting rtl8723e (/lib/modules/3.2.0-30-generic-pae/kernel/drivers/net/wireless/rtlwifi/rtl8723e/rtl8723e.ko): Invalid argument{/code}
then it means there is some compat wireless module especially with rtlwifi.ko module that conflicting with this rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012 driver. You must make sure there were no compat wireless on the system by removing / uninstalling them before doing make. If you were using atheros ethernet ar8161 with compat-wireless or there is the linux-backports-modules-cw-xxx module on system, you must uninstall them first.
