I've been lurking for some answers about the RTL8811AU EDUP and Rosewill G300EX WiFi adapter. The Rosewill adapter that I dug out of my basement picks up wifi signals, tries to connect, and then drops them for no reason I can decipher.

The USB adapter, on the other hand, doesn't even turn on. I do have a USB hub because I thought it was a power issue, but that didn't work. There's a twist; I have no internet access on that computer (The adapters aren't working!) so I can't install any packages. I've even tried USB tethering with an iPhone. I do not have access to wired internet.

My PC is an HP XW4600 running Ubuntu 18.06. I am willing to run some diagnostics if you have any questions, but it is limited- I can't even run ifconfig, because I need to install packages over the internet.

Thanks!

If you can download packages on any other PC, then here's a solution, as described in this post to install RTL8811AU driver:

sudo apt install dkms
git clone https://github.com/zebulon2/rtl8812au.git

now copy that directory over onto the machine that does not have Internet access and execute there:

cd ./rtl8812au
sudo ./dkms-install.sh

Though, in addition to cloning git as mentioned above, you would need DKMS for Ubuntu 18.04, and its dependencies too so have a look here on how to install packages off-line

  • I am not able to install packages. I am going out today to buy a wired ethernet cable, so hopefully that works. – George Vokac Aug 09 '19 at 13:18
  • @GeorgeVokac See edits but an Ethernet cable would be the easiest solution to your problem though... Jags: An edit and an upvote! ;-) – Fabby Aug 10 '19 at 20:37
