Ever since I installed 16.04 on this laptop, I have had the following problem, only on Ubuntu (everything works fine on my Windows side): the wi-fi disconnects after maybe 2 minutes. I can reconnect for another 2 minutes or so by clicking "Enable Wi-Fi" off and on again, or by restarting network-manager from the command line.
Occasionally after doing this a few times, these methods will no longer work and I'll have to restart my computer. Or, sometimes after doing this a few times, the network will then appear connected in the network-manager applet in the top toolbar, but any page will just time out.
I have tried a variety of things over the past year to fix this, to no success; a couple of these attempted fixes caused more wi-fi issues - I'm now back to where I was when I started: wifi connects but cuts out every few minutes.
The attempted fixes that didn't work for me include:
- updating the OS
- installing wicd (which I later removed)
sudo apt autoremove
- starting or restarting network-manager using
sudo service network-manager restart
- setting IPv6 to "Ignore" for the connection I'm trying to connect to
- some others that I've forgotten
So, I am now looking for help with my specific situation because trying similar things I found on Stack Overflow hasn't solved my problem and I'm afraid trying more will worsen the situation again.
Here is the output of wireless-info, during a time when the wifi appeared connected but all pages were timing out: http://paste.ubuntu.com/25582452/ I have a Realtek RTL8821AE wireless adapter on an ASUS A555 laptop.
