I have recently decided to switch to Ubuntu on my personal laptop. I decided to install Ubuntu 16.04 since I was running into issues with version 18.04. After two days, I was able to installed properly on my machine.

I got to add the parameter "pci=noaer" after squash line in the console while booting in order to overcome an error while booting(PCIe bus error).

After that, I was able to use & connect to the internet. After two hours, the internet stopped working. I have try everything & I don't get anywhere.

My network adapter is a RTL8821AE 802.11ac PCIe Wireless Network Adapter. I own a Asus machine and I removed Windows completely so I just have Ubuntu 16.04 installed. Any help will be appreciated it.

I have try updating dependencies, playing with settings, nothing have solved my issue. I am about to quit to be honest.

Edited

Output running the command ip a

Also try sudo aptitude safe-upgrade -y and it didn't solve the issue.

Solution:

I found the answer to my problem. It seems that I needed to install the proper drivers for my Realtek RTL8188. This is the solution:

sudo apt-get install build-essential linux-headers-generic git dkms
git clone http://github.com/lwfinger/rtlwifi_new.git
cd /path/to/rtlwifi_new
make
sudo modprobe -rv rtl8188ee
sudo make install
sudo modprobe -v rtl8188ee

I figured it out using this answer.
