Problem on Xubuntu 14.04 with TP-Link WN822Nv4

Question

I've recently obtained the TP-Link WN822Nv4 (EU) adapter because my onboard adapter doesn't seem to work very well (low signal strength, my phone gets 10x the speeds), however I can't for the life of me figure out how to make it work. I've tried searching the site for similar things (like this and this, the second one reported an error of some kind), but none of them seem to work. My laptop is a HP Pavilion G6-2002SM if it matters.

Output of lsusb ( Device 004 is the adapter I think):

I'm not too familiar with troubleshooting on Linux so I can't figure out how to solve the problem. Any advice?

I am looking into it. But it is unclear which one is installed. My source does not have that ID. And the 3.19 kernel is not supported. I would suggest to upgrade the kernel to 4.4 first. — Pilot6, Jan 22 '17 at 17:44

I didn't notice the kernel version, to update to 4.4 you can

sudo apt-get install linux-generic-lts-xenial

We need to get rid of one of the dkms installs as I am not sure Pilot6 updated his PPA for Trusty

sudo dkms remove rtl8192eu/4.3.1.1.11320.20140505~trusty1 --all

sudo dkms remove 8192cu/1.10 --all

Reboot

Then we can install git and build-essential

sudo apt-get install git build-essential

Then we can clone Mange's github code

git clone https://github.com/Mange/rtl8192eu-linux-driver.git

Then use dkms to add it sudo dkms add ./rtl8192eu-linux-driver

Then install

sudo dkms install -m rtl8192eu -v 1.0

Reboot

Mange's code will support your device because of a commit made 6 months ago

 +  {USB_DEVICE(0x2357, 0x0107),.driver_info = RTL8192E}, /* TP-Link - Cameo /

  #endif

Also removing 8192cu does make sense. – Pilot6 Jan 22 '17 at 17:49
I did not update for trusty, but the deb can be downloaded from the xenial. Also upgrading kernel to 4.4 is recommended. – Pilot6 Jan 22 '17 at 17:50
This worked even without the kernel update, though the speeds are a bit lower than when using Win8. Not sure if this is a consequence of not updating, but the DL/UL are nonetheless way faster than on the default adapter, thanks! – blueshift Jan 22 '17 at 21:36
I do recommend changing to a supported kernel for Ubuntu 14.04 so that you get kernel security updates. If lshw -c video shows only Intel video the kernel update should be painless. The dkms should built the wireless module in 4.4 without issue as that is the kernel I tested it with – Jeremy31 Jan 22 '17 at 21:50
