Rtl8811au

**mariannagr1** · July 5th, 2020

Hi all

I have issues with my wifi USB stick (RTL8811AU). When I first installed Ubuntu 20.04 LTS it was working but this is random after every restart. I have a build-in adapter that I want disabled, since it is terribly old and I use the dongle to connect to wifi.

lshw -c network shows network disabled for my PCIe wireless network adapter, and ok for my ethernet

lsusb finds my wifi stick

Followed advice on this thread: https://ubuntuforums.org/showthread....hlight=rtl8811 and rebooted. Wifi adapter not found.

In synaptic I see I have installed rtl8812au dkms

When I turn on theswitch for wifi/bluetooth, they work using my built-in card, that sucks...

Need some help please (newbie alert lol)

Your wireless info shows that you have:

Realtek Semiconductor Co., Ltd. RTL8723AE PCIe Wireless Network Adapter [10ec:8723]
Subsystem: Realtek Semiconductor Co., Ltd. RTL8723AE PCIe Wireless Network Adapter [10ec:0726]
Kernel driver in use: rtl8723ae

This is not an rtl8811au or even rtl8812au device. It uses the installed and working driver rtl8723ae.

Your report also shows:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

Please find the hardware switch or key combination and turn on the wireless radio. It is currently set to disable the wireless.

This is the internal wifi card. If I turn on the switch, it works. But I don't want it to work. I want my usb dongle on, that uses the driver rtl8811au...

Please try:

Code:

sudo apt update
sudo apt install build-essential git dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo ./dkms-install.sh
sudo modprobe 88XXau
