Will not install: Asus Usb-ax56 Dual Band Ax1800

**chili555** · March 19th, 2024

Did you try a reboot?

After the reboot, did the module load as expected?

Code:

lsmod | grep 8852au

Was a wireless interface created?

Code:

iwconfig

Does it see networks?

Code:

nmcli device wifi list

PS - The 'getting old' card is hard to play here. I am confident that I have at least a decade on you!

No I didn't reboot did not even think about doing that.

Code:

  mike@bastion:~$ lsmod | grep 8852au
8852au              13557760  0
cfg80211              974848  1 8852au

mike@bastion:~$ iwconfig
lo        no wireless extensions.

eno1      no wireless extensions.

mike@bastion:~$ nmcli device wifi list
mike@bastion:~$

IDK if it makes an difference it is a USB wireless adapter which I'm positive most already know that

Let's see if there are any clues in the message log:

Code:

sudo dmesg | grep 8852

**sgt-mike** · March 20th, 2024

that returns

Code:

mike@bastion:~$ sudo dmesg | grep 8852

My very favorite kind of problem: everything looks great except it just doesn't work.

Please shut down the computer. Remove the USB wireless. Start the computer. Open a terminal and run:

Code:

tail -f /var/log/syslog

Insert the USB wireless. Capture the output in the terminal and post it here.

Get out of 'tail' with Ctrl+c.

Is it possible that the USB wireless needs a USB 3.0 (or greater) port but it is currently plugged in to a USB 2.0 port?

Sorry for my delay in posting

I obtained the usb wireless device to use when the media server (or my NFS) was disconnected from a wired connection.
It was/is a nice to have item not required. With that in mind I removed the device driver to get out of the kernal tainted status.

But your last question is a true statement it is a USB 3.0 device plugged into a USB 2.0 port. That could very well be a major part of the problem, even though it's supposed to be backwardly compatible it may not be.

And to praseodym post:

secure boot --- I don't recall setting it up unless it was a default setting from Ubuntu 22.04 server install, and I don't doubt that it is, I'll research that to disable that --- it very well maybe the whole underlying fault
This may take a week or two before I can revisit this small issue (I need to flush a tractor's fuel system, joy oh joy, which means almost complete deck and rear end assembly removal to get to the fuel tank). maybe less.

After reading both post's I'll re-install the driver and do as Chilli stated and capture the output.
Then I'll disable the secure boot if it's enabled after running down the output that Chilli advised.

Post back if you need step-by-step instructions.

I just got this WiFi dongle, which as far as I can figure out is the same one being referred to here.

Because the USB Id's match up:
From the repo: ASUS USB-AX56 with USB ID 0b05:1a62
Fom lsusb: Bus 001 Device 006: ID 0b05:1a62 ASUSTek Computer, Inc.

In this case, im just lucky that the repo README has the USB IDs in the list, a lot of devs don't go to that level of detail.

My question is how did you find this repo?
In the general case...what's the secret sauce for finding a driver?

We normally do a net search for the USB ID and see where it leads, hopefully we find something that is patched for newer kernels
Sometimes for Realtek wifi you can search the /os_dep/linux/usb_intf.c for part of the USB ID

Ahhh ****, I ran into issues compiling the module.
I'm on a Raspberry Pi, which has a + in the kernel release version (5.4.79-v7+). apt treats that as a special symbol.
Here's how to install kernel headers for RasPi - apt install raspberrypi-kernel-headers

Next issue I ran into is that my kernel was too old.
The ole apt-get dist-upgrade sledgehammer solved that for me

She's compiling now!
