I don't know if this has been asked before, but the internet (ethernet and wifi) is constantly disconnected. I've checked the router, via other devices (such as cell phone and tablet) and access to internet is fine. Even when I boot Windows 7 on my computer it's able to connect and stay connected. When I'm running ubuntu (15.04 I believe), when I first start it up it connects just fine to the Wi-Fi network I use. But after using the internet for some time it all of a sudden disconnects and I'm unable to connect again to the router I use. It's says "wifi networks disconnected". But the strange part is when I boot Windows 7 on my computer it's able to stay connected to the Wi-Fi network and access the Internet, it's just the Ubuntu OS I seem to be having some trouble with here.


It may just be an internal error.

sudo apt-get purge network-manager
sudo apt-get update
sudo apt-get autoremove
sudo apt-get upgrade
sudo apt-get install network-manager
sudo apt install ubuntu-desktop

Do that then reboot.

  • Well, that did seem to help. But I notice that when I connect a bluetooth headset to it, it disables the wifi. Any advice on how to fix this? – 234Nico Aug 1 '15 at 3:25
  • @234Nico I know what's causing it, but unfortunately, not how to fix it. This is a problem caused by the motherboard not being able to port both wireless, and bluetooth devices at the same time. I'd recommend asking an entirely new question on it. – David Aug 2 '15 at 5:55
  • Ok, thank you though for all of the help! Even though you may not know how to fix it, I still am very happy that I know now what's causing the problem. – 234Nico Aug 6 '15 at 4:30

    @UmarAsghar This answer is over two years old, and is statedly designed around 15.04, and as such may not work with all versions – David Dec 21 '17 at 15:08

    @ShivaManhar See the answer below this, by NatoBoram It will fix the issue you are having – David Jan 18 '19 at 0:49

If you decide to use David's answer, the Settings shortcut might be missing. To fix that, I used cshubhamrao's answer to reinstall ubuntu-desktop.

sudo apt purge network-manager
sudo apt autoremove
sudo apt update
sudo apt full-upgrade
sudo apt install network-manager
sudo apt install ubuntu-desktop
