So I have an Asus x200M which I bought a couple of years ago. I used Windows 10 (which worked fine) until a couple of days ago when I decided to switch to Ubuntu 16.04. I made the switch and everything worked fine until I realized that the wifi was working very badly and that after waking from hibernation the icon would change as if my connection was a wired one instead of a wireless one.
I checked some posts and I found that some people were having the same problem as me. One recommended upgrading the distro might solve the problem. I upgraded to 16.10 and nothing. Further investigation led me to check my wifi card using
sudo lshw -class network
and with that I get the following:

which leads me to believe that my wireless adapter is the Realtek RTL8188EE Wireless Network Adapter. Further googling action led me to this post in which a user sugests doing the following in a terminal
sudo apt-get install build-essential linux-headers-generic git dkms
git clone http://github.com/lwfinger/rtlwifi_new.git
cd /rtlwifi_new
make
sudo modprobe -rv rtl8188ee
sudo make install
sudo modprobe -v rtl8188ee
And I tried that, and I get the following
mario@mario-X200MA:~/rtlwifi_new$ make

modprobe: ERROR: could not insert 'rtl8188ee': Required key not available
The last line is the one that baffles me, because it tells me that the required key is not available. I did some more googling and found that with mokutil I could disable the Secure Boot, but I ran that in a terminal and it outputs
This system does't support Secure Boot
So my question is, what do I do now? Do I try to sign the package myself? Do I even need to sign it, given that my computer doesn't support Secure Boot? Have I followed a wrong path?
[EDIT: So after tinkering with the BIOS I found out that the Secure Boot option is a bit difficult to find, but there it is, under a couple other options]
So I was able to try the method stated above, and while it did change the driver, it did not solve the problem. I've been having some packet loss that gets worse from time to time. Right now is at 13%.
