I'm an Ubuntu rookie with an unresolved wireless internet connection issue. I've spent a lot of time fiddling around in my never-ending quest to get my connection working properly, but my inexperience is beginning to show and I need a little extra help.

The issue in brief: slow speed (Ookla clocks in at ~5-8Mbps download speed - it should be ~20) and connection dropouts occur every ten minutes.

OS: Ubuntu 14.04
Kernel: 3.13.0-32-generic

I've done some homework and tried a lot of solutions from these forums. I think ultimately the problem is going to be with the driver rtl8192ce. I've tried changing it to rtl8188ce using FreedomBen's tutorial, but I can't fathom how to use script for the automatic installation (I have problems with manual installation too, but I don't want to ask two questions in one post, so I'll save them for later). Can anyone help me out? I think I have the .zip downloaded if that's important.

I've included outputs to various Terminal commands below that may also prove helpful.

Sorry if I've missed something obvious, I'm green as grass but, as you can see, willing to suffer a lot of hassle to avoid returning to Windows.

Save any unsaved work before you start as the last command will reboot.

Open a terminal to copy and paste the following commands one line at a time to install the driver. Press enter after each command line. Do not close the terminal untill you are completely finished with the installation.

first command:

sudo apt-get update && sudo apt-get install git gcc build-essential linux-headers-generic linux-headers-$(uname -r)

second command:

cd && git clone https://github.com/FreedomBen/rtl8188ce-linux-driver.git

third command:

cd rtl8188ce-linux-driver && sudo make

fourth command:

sudo make install && sudo reboot

notes

When it asks to change branches type for you after the third command, select "y" and at the end of the fourth command it will say something about turing power-save mode off, just select "n" or no because that is not an option for this driver in this version of ubuntu anyway but if you select yes it won't matter you'll just recieve an error that is of no consequence.

For 16.04

sudo apt-get update
sudo apt-get install git gcc build-essential linux-headers-generic linux-headers-$(uname -r)
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo modprobe -r rtl8192ce
sudo modprobe -r rtlwifi
sudo modprobe rtl8192ce

Reinstall the driver package: 

sudo apt-get --purge autoremove linux-firmware-nonfree && sudo apt-get install linux-firmware-nonfree

then reboot.
