Asus USB-AC53 Nano driver redux - not working

**chili555** · August 5th, 2020

Perhaps it is the device itself that is defective. Does it work in other computers? Windows??

I got same idea, but on windows machine it installs and works w/o problem. I ordered replacement mobo, a bit hard to buy new after 15 years

Meanwhile i dug out my old HDD with Windows. All USB ports seems to work and dongle installs. Don't know what to think.

With your Ubuntu HDD back in, insert the device, boot up and show us:

Code:

lsusb
dmesg | grep usb

As the output may be lengthy, psate the result here and give us the link.

lsusb still doesn't work. Dmesg output attached.

Let's try a newer version of the driver. Remove the device from the USB port. From the terminal:

Code:

sudo dkms remove 8822bu/1.1
git clone https://github.com/cilynx/rtl88x2bu.git
cd rtl88x2bu/
VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER} 
sudo dkms install -m rtl88x2bu -v ${VER}

The 'build' step takes a few minutes; please be patient.

Insert the device and show us:

Code:

iwconfig
dmesg | grep -e 88x2 -e wlx

Code:

sudo dkms remove 8822bu/1.1

didn't work, got to

Code:

sudo dkms remove 8822bu/1.1 --all

reboot... and.... tadam!

Code:

szydas@ubunciak:~$ iwconfig

Hi, how to solve this problem

Hi mapst and welcome to the forum, if you have a question please state the issue in your own thread and do not post in someone else's asking for help, it gets confusing for everyone involved.

Thanks
