Recently I installed Ubuntu 16.04 but cant get the usb wifi adapter to work properly , can anyone help me?

When wifi adpater is plugged , the lsusb output:

Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

When wifi adapter is unplugged , the lsusb output:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

    Are you in a virtual machine? You cannot use the host's usb devices unless you explicitly select it from your VM software. –  Sep 04 '16 at 16:38

Mange updated his [github](https://github.com/Mange/rtl8192eu-linux-driver/commit/56ccb6b05cff08de1beddbbd03efdb36eff1416d) to support the device – Jeremy31 Sep 04 '16 at 20:07
  • @CelticWarrior, I am not the OP, but I can assure this is not necessarily a VM problem, since I'm experiencing the same issue on my single-boot Ubuntu desktop. – Waldir Leoncio Sep 15 '16 at 14:51
  • @DavidFoerster, thanks for the link, but I believe this might not be VM-related. I am experiencing the very same issue on my single-boot Ubuntu desktop. – Waldir Leoncio Sep 15 '16 at 14:52
  • @Waldir Leoncio - Doesn't yours appear listed? The main problem here is out to "move" the device from the host to the guest OS in VMWare, as shown by the results above. If your doesn't work follow Jeremy31's comment. –  Sep 15 '16 at 14:57
  • @CelticWarrior, it doesn't appear listed, not even on http://www.linux-usb.org/usb.ids. However, I still managed to make it work by following your tip. I'll explain it in my answer below. Thanks! – Waldir Leoncio Sep 15 '16 at 16:14

  • @DavidFoerster How is it related to a virtual machine? – Pilot6 Sep 15 '16 at 16:51

I was going through the same problem. Here is how to solve it, even though it doesn't solve the nameless problem:

If you have wired internet available to your problem PC

  1. Follow this answer, which adds Pilot6's rtlwifi PPA to your sistem and installs the required rtl8192eu-dkms package.

If you have no internet access in your computer

  1. Find another computer with internet access to download the rtl8192eu-dkms package manually.
  2. Access https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi
  3. Click on "View package details"
  4. Filter your Ubuntu codename (16.04 LTS is Xenial).
  5. Click on the triangle to open more options of "rtl8192eu-dkms - 4.4"
  6. Download rtl8192eu-dkms_4.4_all.deb.
  7. Transfer this file to your target PC
  8. Install the file on your target PC, either through the Software Center or the Terminal (by issuing dpkg -i <filename> in the appropriate folder).
  9. Re-plug your dongle.

Here's a screenshot to better show the location of the download link:

  • @DavidFoerster You are wrong. The system does see the device. It is 2357:0109 – Pilot6 Sep 15 '16 at 16:49
  • it does see the device , it just doesn't recognise it , installing the drive should add the required udev config to have lsusb identify it – Amias Sep 15 '16 at 16:50
  • This is a correct answer. You can use my PPA. See the last comment under your question. – Pilot6 Sep 15 '16 at 16:52
  • @Waldir Leoncio I do not have internet on my computer. I followed your answer up to #8 but it resulted in package dkms not installed . Any help? – user278121 Sep 29 '16 at 09:08
  • @user278121, what is the terminal command you issued and what was the output? – Waldir Leoncio Sep 29 '16 at 09:10
  • I copied the file rtl8192eu-dkms_4.4_all.deb in the Downloads folder of the target PC. cd into Downloads folder and ran this command: sudo dpkg -i rtl8192eu-dkms_4.4_all.deb – user278121 Sep 29 '16 at 09:14
  • Looks right. What was the output? Alternatively, try installing it by double-clicking on it. This should open the installer. – Waldir Leoncio Sep 29 '16 at 09:21
  • This was the output. `(Reading database ... 173068 files and directories currently installed.) Preparing to unpack rtl8192eu-dkms_4.4_all.deb ... Unpacking rtl8192eu-dkms (4.4) over (4.4) ... dpkg: dependency problems prevent configuration of rtl8192eu-dkms: rtl8192eu-dkms depends on dkms (>= 1.95); however: Package dkms is not installed. dpkg: error processing package rtl8192eu-dkms (--install): dependency problems - leaving unconfigured Errors were encountered while processing: rtl8192eu-dkms` – user278121 Sep 29 '16 at 09:40
  • When I tried double-clicking, the Software Center window appeared but clicking on the Install button from there didn't change anything on the screen. – user278121 Sep 29 '16 at 09:50
  • @user278121, well from "dependency problems" it seems like you're missing a package required by dkms to be installed. I'd recommend checking into that. Are you on 64 bits? – Waldir Leoncio Sep 29 '16 at 10:07
  • I installed the dkms package from https://launchpad.net/ubuntu/+source/dkms and then following your answer worked. The internet is now working fine. Thanks for all your help. – user278121 Sep 29 '16 at 10:15
  • @user278121. That is awesome, please remember to upvote! – Waldir Leoncio Sep 29 '16 at 10:17
  • @Pilot6 do you know of a working version for TL-WN823N US v3 by chance? These packages install but can't associate with a network. – emkman Jan 01 '19 at 01:04

The driver for this dongle can be installed by

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

  • Tested on 16.04 x64, kernel 4.4.0-36. It works great for me. My dongle: TP-LINK TL-WN823N(EU) "VER 2.0". – gorlok Sep 16 '16 at 23:43
