    [SOLVED] Realtek RTL8192SE enabled but cant see wifi networks

    Hi I just finished installing Lubuntu 14.04 on my netbook and works great! In the installation process I have enabled wifi and all the update proccess was made through it.

    After installation finished, I rebooted, but the WIFI stopped working!

    I managed to add Network Manager Applet and my WIFI adapter appears there, but when clicking the WIFI icon, no networks appear!

    I'm really missed here, because on installation, my WIFI was working just fine, but after reboot, is stopped working

    Here is the output of Wireless Info Script

    Hi, well, after rebooting several times, I got the Connections Manager system tray icon and was able to connect to my wifi networks.

    Thanks anyway.
