I just installed Elementary OS on my ASUS laptop. The internet (WiFi) seems to stop working (though it shows as connected) after some time of use. I have noticed this happens when I haven't booted with the charger plugged. [EDIT: nope, it stops either way]

I checked the power management settings by doing an iwconfig wlan0 and it says power management: off

I have no idea, I would really love to use elementary OS, but cannot if the internet does not work :(

EDIT: On running sudo lshw -C network

EDIT: Works perfectly fine on Windows (so nothing wrong in the BIOS/hardware)

  • What's it your wifi card? Try in terminal "sudo lshw -C network" and add the output to your question editing it. – bitseater Apr 22 '16 at 4:59
  • Thanks, I did that. Hope we are able to figure something out!! – user1836386 Apr 22 '16 at 5:08
  • Do you think installing some other proprietary driver will help? If so, how do I go about it? can you help? – user1836386 Apr 22 '16 at 6:42
  • edit, nope... still crashed [SOLVED] [NOT REALLY] ... Re-installed the OS...I'm guessing it was one of the updates that messed things up.. DO NOT UPDATE!! – user1836386 Apr 22 '16 at 7:01
  • nope, crashed again! – user1836386 Apr 22 '16 at 7:19

The Realtek drivers have so many issues on Ubuntu. There are some drivers forked by the community, like "rtlwifi_new" that you can find at github.com

Install instructions:

From terminal :

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install 

Reboot your system and try again.

Source and more info: askubuntu.com

If it doesn't work, open a terminal and try echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf how it's indicated in the link below.
