You can install a driver for Ubuntu 16.04 this way

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt update
sudo apt install rtl8192eu-dkms

You need to be connected by wire for that.

This is my PPA. I added the ID for this adapter to official Realtek drivers. They always forget to do it.

If UEFI is used in your computer, you need to disable SecureBoot to load the kernel module.

i have tried this once even i tried it once again – Akash Mahalik Jun 29 '16 at 14:28
What do you mean you tried? You need to use only one solution, not many. They conflict. This driver should work. Maybe you installed another driver from the same PPA or a driver from git. You need to remove everything else. – Pilot6 Jun 29 '16 at 14:29
how do i remove the ones i have already installed ? – Akash Mahalik Jun 29 '16 at 14:32
It depends on what did you install. To start please give output of dkms status. – Pilot6 Jun 29 '16 at 14:33

Remove 8192cu by sudo dkms remove 8192cu/1.10 --all, then run sudo modprobe rtl8192eu and insert the dongle. It should work. – Pilot6 Jun 29 '16 at 14:39
my current dkms status rtl8192eu, 4.3.8.12406.20140929~xenial2, 4.4.0-21-generic, x86_64: installed |||||| rtl8192eu, 4.3.8.12406.20140929~xenial2, 4.4.0-28-generic, x86_64: installed – Akash Mahalik Jun 29 '16 at 14:42
it says modprobe: FATAL: Module rtl8192eu not found in directory /lib/modules/4.4.0-28-generic – Akash Mahalik Jun 29 '16 at 14:44
Oops. Hold on, I will check the driver. – Pilot6 Jun 29 '16 at 14:44
The correct name is 8192eu. Run sudo modprobe 8192eu and test. – Pilot6 Jun 29 '16 at 14:47
modprobe: ERROR: could not insert '8192eu': Required key not available – Akash Mahalik Jun 29 '16 at 14:50
Oh, this can be easily fixed. Disable SecureBoot in BIOS. The module is not signed and SecureBoot does not let to load it. – Pilot6 Jun 29 '16 at 14:53
how do i disable secure boot ? – Akash Mahalik Jun 29 '16 at 14:53
Just disable SecureBoot and the issue will be fixed. – Pilot6 Jun 29 '16 at 14:53
Ok got it i will run my BIOS and come back – Akash Mahalik Jun 29 '16 at 14:54
Thanx thanx a lot ..is there any way i can give u 10-15 green ticks and 20-30 upvotes :P – Akash Mahalik Jun 29 '16 at 14:59
No, please do not do it. This is not allowed and will be automatically reverted including the fair one. – Pilot6 Jun 29 '16 at 15:00
just kidding :P – Akash Mahalik Jun 29 '16 at 15:03
