Ubuntu – install usb wifi adapter on ubuntu 14.04

14.04driversnetworkingusbvirtualbox

I have windows 10 on my laptop and I run Oracle VirtualBox with ubuntu 14.04.5 LTS 64 bit on it.
I bought tp-link usb to wifi adapter – TL-WN821N v5.

I am try to connect the usb to the vm so it have wifi and wireless functionality in it.
in vbox there is option to connect the usb direcly to the machine so the the windows 10 dont detect the usb.

lsusb detect the adapter:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 80ee:0021 VirtualBox USB Tablet
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

but lshw -C network

and iwconfig 

lo        no wireless extensions.

eth0      no wireless extensions.

wont seem to identify the new hardware:

I thought the problem is that need some driver – so I tried to install the driver:
http://www.tp-link.com/en/download/TL-WN821N.html#Driver
but make give me syntax errors (and i think there easier way)

I followed this link
DLink DWA 131 wireless adapter not working on ubuntu 15.10
and when i run apt-get install rtl8192eu-dkms
I get this:

Reading package lists... Done
Building dependency tree
Reading state information... Done
rtl8192eu-dkms is already the newest version.
The following packages were automatically installed and are no longer required:
  culmus linux-headers-3.13.0-32 linux-headers-3.13.0-32-generic
  linux-image-3.13.0-32-generic linux-image-extra-3.13.0-32-generic
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 12 not upgraded.

and it still dont work.

The laptop (and vm) connected to ethernet directly.

kernal version- 4.4.0-45-generic

thank you for help!

I was unable to use TL-WN812N on ubuntu 14.04 (not vbox). Attempted to download the driver from tp-link website but pt-br tp-link website version have no driver link there. Tried google and found your question.

I could find the driver following the link http://www.tp-link.com/en/download/TL-WN821N.html#Driver you mention but I faced the same makefile issue. But I could fix it: the guy who wrote the Makefile did a great job but the guy who created the driver zip root folder I was not aware of what he was doing. He named the driver folder TL-WN821N(EU)_V5_160315_Linux then when you run:

sudo make
"******************************************"
"NO SKRC,we will use default KSRC"
"******************************************"
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/3.13.0-106-generic/build M=/tmp/TL-WN821N(EU)_V5_160315_Linux/Driver  modules
/bin/sh: 1: Syntax error: "(" unexpected
make: *** [modules] Error 2

Bash gives error because the path name of driver makefile is not escaped. I renamed the folder to tl-wn821n-v5-160315-linux and it worked from building to connecting to internet.

Hope this help.
