What I’ve Tried:
My workstation is basically fully offline right now as I do not have a way to connect it with a wired network as it sits quite a distance away from my router. I also do not have a way (at the moment) to move it to closer to my router to connect it with a wired cable (a relatively small one that I have). So, after installing the OS, anything that I had to update or install, I had to first download on my laptop and then copy it over on a USB to this workstation, and then finally install it.

I tried to collect the output using the wireless-info script but even after following the steps to make it executable, it did not work. A manual sh -e ./wireless-info in Konsole, generated a syntax error.

I have tried to install compatible Wifi drivers available for AX900 from Tenda’s website as well as from a git library and the driver installation is successful, but the Wifi interface does not show up in Wifi & Networking.

lsusb output shows this device: Bus 001 Device 006: ID 368b:8d81 AICSemi AIC 8800D80

sudo dmesg | grep firmware:

I am fairly new to Linux, so have limited know-how of the platform. I am open to learn though. If someone could provide guidance/steps that I could try based on the information I have provided, it will be really helpful. Thank you.

I did cross post from askubuntu but only in the hope that I would get a better response here. If needed, I can delete my post there as it does not have some of the details that I posted here in terms of the issue. I still need guidance to troubleshoot this issue. If someone can help diagnose it, please do reply. Thank you.

It’s fine having both. I merely comment to make other possible helpers aware.

That said, at AskUbuntu is where you should post the most information. It’s a Q&A format, not a forum, and as such the question should contain all the relevant information and be focused on one issue. In forums you can get away with much less, someone at some point point will ask about what they think is missing in a thread.

Have you checked if WiFi is turned off in the UEFI settings utility? We are assuming that you are not dual booting with Windows. If WiFi is turned off in Windows, then it is unlikely that Kubuntu will be able to turn it back on. That used to be the problem years ago. I do not know if it is still a problem.

I do not use Kubuntu but in Ubuntu we can turn off WiFi. Has that happened? Did this machine come with a built-in WiFi adapter?

Run

rfkill list

That will tell you is WiFi is blocked in hardware and software. Hardware blocked = no driver. Which you perhaps already know. But we do not.

Regards

It’s still a problem and it may also be ‘highjacked’ by Windows even if turned on. When dual-booting disabling Windows’ Fast Startup and shutting down properly before booting Ubuntu again is a must. Also recommended to disable Fast Boot in UEFI.

Hey!

I hope the community had a fun weekend!

I do not dual boot with Windows. That would be an overkill for the resources available on this workstation. No inbuilt Wifi. No fastboot configuration available in my Dell BIOS. This is a Dell Precision 3620 by the way. I didn’t state this earlier, so just adding this piece of info.

rfkill list → no output (blank)

I noticed something new while the system was booting up. There’s a timeout error encountered while the following service starts. It seems to wait for exactly 2 mins and then errors out.

systemd-networkd-wait-online.service

Does this point to a possible issue?

@celticwarrior @graymech - anything from the information that I have shared, point to something? Maybe I just don’t know how to do this correctly but I’m really looking for some guidance to troubleshoot this issue further. Thanks.

I would remove the modules you installed and try GitHub - shenmintao/aic8800d80 as that builds and works fine with my similar wifi on the 6.17 kernel

I tried using the drivers from shenmintao’s repo but that gives me a different set of errors.

At this point, this seems like a lost cause to me. It should not be this difficult to get a Wifi dongle to work on Ubuntu. I understand that a lot of people here are trying to help each other out. However, if even simple things like these give such a hard time, new comers like me tend to get pushed over to using a different OS which may not be preferred but at least most things work out of the box. I wish there was more from a base OS perspective that Ubuntu OS devs could do to make things simpler but that’s just me. Maybe I’m just looking at this all wrong and I should have referred to the Ubuntu guides to find a compatible dongle in the first place. I would not be in such a mess. :man_shrugging:

Might want to try a different USB port. Those errors are from before the driver even loads

I completely removed the drivers and reinstalled them. Rebooted Ubuntu to see if that would make any difference but it did not. The dmesg | grep aic shows the following error:

usb_err:<aicwf_usb_rx_submit_all_urb,232>: bus is not up=0

A google search shows that this may have something to do with missing firmware, driver loading failure, or power management issues during initialization. None of them seem to be the thing that is happening. The full dmesg output is as below:

The same USB ports work for other devices that I connect there. Anything else that I could check?

I think there is some USB bus issue with that wifi on your computer. I picked one up just because it was really cheap. I know the driver isn’t the best but it is all there is. I might look into it more if I can change the amount of debug info that comes through dmesg with the driver

There is a list of Linux kernel supported USB wifi at a link on GitHub - morrownr/USB-WiFi: USB WiFi Adapter Information for Linux

Hi Jeremy,

While I have considered buying a different wifi adapter, I also tried to use an AV500 TP-Link network extender that I have. However, I found out that it does not support connecting to my router via Wifi (has to be hard-wired to the router). Another thing that I found out about my router (which is provided by my ISP) is that it does not support WPS. So, I have limited options for the hardware that I can use to hook up my workstation wirelessly with my Wifi. I spent the last week trying all of these options with hardware that I already had but was not successful in getting Wifi connectivity to the workstation. I had to eventually move the workstation back to its original place as I had kept it on my dinner table temporarily (well, it was there for about 2 weeks!) :stuck_out_tongue:.

Unless you got a chance to look at porting one of the drivers available to work with the Wifi adapter that I have, I believe I do not have any option but to buy a new Wifi adapter that is compatible with Linux. I have referred to the link that you gave and am considering my options from that list.

Thank you so much for trying to help thus far!

@Jeremy31 - I also tried downloading the BrosTrend Linux driver for AIC8800 (as suggested by morrownr here and that seemed to go through a much better install experience. However, the end result was still the same. While loading the driver, the error logged in the kern.log is the one below (as it was with the other drivers that installed successfully).

usb_err:<aicwf_usb_rx_submit_all_urb,234>: bus is not up=0

I have also in the process tried to upgrade to the latest Linux kernel version i.e. 6.17.0-14-generic but that has the same issue too. Still trying to find my way out… :man_shrugging:

16

This is a hurray moment! I did eventually find a solution to this issue!! The real credit goes to a user who in the process of working with this issue, built his own solution…

I had to dig through the entire thread here to get to the actual part where he posted his steps that got things working for him i.e. here!

I am posting the solution steps (as is) here just in case anyone else stumbles across this same thing.

# Step 3: Load drivers in correct order
sudo modprobe aic_load_fw
sudo modprobe aic8800_fdrv

# Step 4: Add USB IDs (CRITICAL - driver doesn't have them built-in)
echo "a69c 8d80" | sudo tee /sys/bus/usb/drivers/aic_load_fw/new_id
echo "368b 8d81" | sudo tee /sys/bus/usb/drivers/aic8800_fdrv/new_id

As soon as I ran the commands to add the vendor and driver IDs to the new_id files, and unplugged and plugged my Wifi adapter back in, it worked!! I finally have Wifi connectivity on my workstation, YAY!!

I am curious though as to why these IDs were required to be present in the new_id files. I’m sure part of it is because I don’t know their purpose, but then why did the driver installs not put those IDs in the files if the driver would not work without them?

Hi @Jeremy31,

Here’s the output that you requested. Just to clarify, after making the change that I mentioned in my last post, the adapter worked but after a reboot it did not. I had to repeat that change again. I created a custom service which runs a script. The script will make the same changes at every boot.

The newid thing wouldn’t have been needed with the driver I recommended as I checked the alias list for both those drivers but at least the Brostrend seems to be dkms

20

Unfortunately, that driver didn’t work in my case. Not sure why if you’re suggesting that it creates the required aliases automatically. Eventually, it was the BrosTrend Linux driver that got things working for me along with the new_id changes. I could try the same thing again with the shenmintao driver as well to see if it makes any difference because essentially, I was getting the same error with both.

Another thing is that the Bluetooth does not work with this driver, so this is still a dirty workaround just to make the Wifi work. I am not complaining though because Wifi is all that I needed. Bluetooth was never a concern.

Let me know if you need me to try anything else which might give additional insights. I could give it a shot now that I have a fallback available to make things work.
