as of right now I have no way of connecting to the wireless networks in my fresh install of Ubuntu 15.04. My wireless adapter is a TP-Link Archer T4u ac1200. I have another computer that I will be able to install drivers from over USB, but I'm not sure how. I have absolutely no internet at all and also, I can't install drivers in additional software either. I'm pretty sure Ethernet will work but I am unable to move my PC downstairs near my modem. How can I make it so that I can connect to wifi?

Edit

The output of lsusb

I obviously see my M65 RGB (Corsair) and my external HDD (Seagate RSS LLC) but I'm not too sure about my keyboard, which is an AZIO MGK1-RGB.

  • what is the output of 'lspci | grep -i network'? – Ashu Mar 26 '16 at 5:05
  • When I enter that command in terminal I don't get any output at all. – Execution Mar 26 '16 at 12:47
  • Please edit your question to add the result of this terminal command: lsusb. You may omit all listings that are not the wireless device if you wish. – chili555 Mar 26 '16 at 13:01

  • Was the Archer USB wireless plugged in at the time? I don't see it. – chili555 Mar 26 '16 at 13:28

One of the packages you need, dkms, is on the install DVD or USB; insert it and drill down to pool > main > d > dkms and drag dkms to you desktop. Then install:

cd ~/Desktop
sudo dpkg -i dkms*.deb

Now download this package on some other computer and transfer it by USB or similar to your desktop: https://github.com/abperiasamy/rtl8812AU_8821AU_linux/archive/master.zip Right-click it and select 'Extract Here.' Now, back to the terminal:

cd ~/Desktop
sudo dkms add ./rtl8812AU_8821AU_linux
sudo dkms install -m 8812au -v 1.0

Reboot and your wireless should be working.

NOTE: This depends on the presence of build-essential and linux-headers-generic. Please check:

sudo dpkg -s build-essential
sudo dpkg -s linux-headers-generic

If either is not installed, I will edit my answer to propose a further solution.

  • I don't have a DVD drive, I got rid of it because it made the front panel of my case look ugly. I don't have a way to use the driver install DVD. Or do you mean the USB I used to install Ubuntu? That won't work either, it won't allow me to access those files. – Execution Mar 26 '16 at 15:04
  • Yes, the Ubuntu install USB. Why are you unable to access those files? Are you running Ubuntu from the USB or is this a full installation? – chili555 Mar 26 '16 at 15:06
