I am attempting to install a driver for a TP-link TL-WN 823N wireless adapter. I have already posted on this forum, but although I’ve made some progress, I still haven't been successful in getting the wireless set-up to work. I am not very au fait with Ubuntu, and certainly very new to the process of installing drivers.
I followed the suggestions on this forum to use Pilot6’s PPA. However I’m still unable to link to the router for my home PC or the router we use in a small shop I manage.

The code I used as per Pilot6 was: 

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

This seemed to work OK – no errors. However I still can’t access the internet via the dongle. The dongle does work on my daughter’s PC which runs on Windows.

When I run nmcli dev on my home PC I get the following:

DEVICE /                             TYPE   /      STATE          
enx98ded01807c2        /       wifi       /      disconnected  
eth0                /                      ethernet  /    unavailable  
lo                          /                loopback  /  unmanaged

When I type in lsusb, again on my home PC, I get:

Any help would be gratefully received

  • Did you disable Secure Boot in BIOS? – Pilot6 Feb 04 '17 at 13:31
  • No I didn't, because I didn't know I had to, and I don't know how either. Are you able to help with that? Thanks – Tim Feb 05 '17 at 10:53

  • Thanks for that Pilot6, but I have tried 2 of the ways now (of disabling Secure Boot) and neither have worked. When I went the mokutil route, I entered : sudo mokutil --disable-validation and got back EFI variables are not supported on this system. – Tim Feb 05 '17 at 18:29
  • And when I followed the method in the wiki I got the following: sudo: update-secureboot-policy: command not found – Tim Feb 05 '17 at 18:31
  • It is better to switch it off from BIOS. But maybe you do not have UEFI. – Pilot6 Feb 05 '17 at 18:49
  • Oh dear!! What is UEFI? I tried doing ESC when the PC was restarting, but it didn't give me a menu I recognised. – Tim Feb 05 '17 at 22:33
  • @Pilot6 Thanks for your help so far - I have tried hitting esc, F2, F12, del during the boot-up process; using esc I get one screen which just gives me 3 boot options, but no option to disable Secure Boot; using F12 eventually takes me into what looks like a grub screen, but I have no idea what I'm doing there. Should I be starting a new question about how to get into BIOS? – Tim Feb 06 '17 at 09:13
  • What is your BIOS and how to get there is off-topic. You need to look into your computer's manual. – Pilot6 Feb 06 '17 at 09:21
  • @Pilot6 Yes, I thought so - I will have to ask the chap who installed Ubuntu on this PC for me. Thanks again for your help so far. At least I've learned more about using the Ask Ubuntu forums!! – Tim Feb 06 '17 at 10:00
  • I have got into what I think is BIOS, but I can find no option there to disable Secure Boot – Tim Feb 06 '17 at 13:34
  • Maybe it is not an UEFI. – Pilot6 Feb 06 '17 at 13:38
