Help installing 0bda:0811 Realtek Semiconductor Corp

Networking
#1

I was running my OS off a USB stick fine and the wifi was working. I installed it to my SSD and setup again but now the WIFI adaptor isn’t working.

I followed the first time Having problems seeing my wifi Ubuntu Gnome 16.04 and it worked but since installing onto the SSD and doing the same its not working.

No wlan0 interface found
Please check drivers, try lsusb to check USB device is present

Ive also tried

sudo apt purge rtl8812au-dkms
sudo apt install git
git clone https://github.com/gnab/rtl8812au.git
sudo cp -r rtl8812au  /usr/src/rtl8812au-4.2.2
sudo dkms add -m rtl8812au -v 4.2.2
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2

Any advise? I think from trying to fix it ive been making it worse.

Fixed.

I wiped the SSD and put the image on again.

Then straight away did

sudo apt purge rtl8812au-dkms
sudo apt install git
git clone https://github.com/gnab/rtl8812au.git
sudo cp -r rtl8812au  /usr/src/rtl8812au-4.2.2
sudo dkms add -m rtl8812au -v 4.2.2
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2

Rebooted and its working.

this indeed works 12/2019. If you can’t get ethernet to the rig and want to get on via wifi, you can download the git to a zip on a usb media and insert it into hive and mount it and follow the same directions and you should be on your way.

insert stick
sudo fdisk -l ( should be /dev/sdb1)
mkdir /media/usbstick
sudo mount -t vfat /dev/sdb1 /media/usbstick
cp /media/usbstick/filename.zip ~
cd ~
mv filename.zip rtl8812au.zip
unzip rtl8812au.zip

sudo cp -r rtl8812au /usr/src/rtl8812au-4.2.2
sudo dkms add -m rtl8812au -v 4.2.2
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2

reboot and you should be online or you can configure at this point
