Okay so I just fell over something that could help you. I use the T9E network card as well and everything works for me:

  1. Open the Software & Updates application
  2. Go to the Additional Drivers tab
  3. Look for the Broadcom Limited: BCM4360 802.11ac Wireless Network Adapter device (this is your TP-Link)
  4. Choose the Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary) option to enable it

I had similar problem. The driver wasn't install by itself:

Run

apt-get update && apt-get upgrade && apt-get dist-upgrade

Reboot and run

apt-get install broadcom-sta-dkms

modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

modprobe wl

And reboot again

Link to topic when i found solution:

If you have internet while you install Ubuntu it will install the T9E driver by itself. I sadly do not know how to do it after install. I do have a working T9E driver. If you know any way I can help do ask.

Why are you trying a T4U driver when you have a T9E card? The T4U is a USB device uses a Realtek chip. The T9E is a pcie card and it uses a Broadcom chip hence you need to use the Broadcom wl driver.
