Fixing Wi-Fi Not Working on Ubuntu (Dual Boot with Windows)

Recently, I faced an annoying issue after booting into Ubuntu which was running alongside Windows(dual boot) on my ASUS VivoBook 14 (Model: M413IA) .My Wifi was not working , i switched to Windows and it worked just fine. MyWifi card is Intel Wi-Fi 6 AX200 card.

After a lot of digging, debugging, and trial-and-error, I figured out the root cause and fixed it. This post documents that journey, in case anyone else is facing the same issue.

The Symptoms :

In Ubuntu, running:

nmcli device

The output


DEVICE           TYPE      STATE                   CONNECTION         
enxca89f39a6d94  ethernet  connected               Wired connection 1 
lo               loopback  connected (externally)  lo                 
docker0          bridge    connected (externally)  docker0

Wi-Fi was completely missing.

Then I checked the network hardware:

sudo lshw -C network

The output:

*-network UNCLAIMED
   description: Network controller
   product: Intel Corporation Wi-Fi 6 AX200

The device was "unclaimed" — a clear sign that the kernel recognized it, but no driver was managing it.

The Error in Logs

To get more detail, I ran:

dmesg | grep iwlwifi

It showed

iwlwifi 0000:01:00.0: probe with driver iwlwifi failed with error -110

error -110 typically points to a timeout, meaning the device isn’t responding correctly during initialization.

What Didn’t Work

I tried a lot of common fixes:

None of these worked.

The Real Cause: Windows Fast Startup

Eventually, I booted back into Windows to double-check if the card was functional. It was. This confirmed that the hardware wasn’t faulty.

Then I remembered that Windows Fast Startup sometimes causes devices to be left in a low-power or suspended state — especially Wi-Fi and Bluetooth cards.

This was the key.

The Fix That Worked

Here’s exactly what I did:

  1. Booted into Windows
  2. Went to Control Panel → Power Options → Choose what the power buttons do
  3. Clicked “Change settings that are currently unavailable”
  4. Disabled: Turn on fast startup (recommended) remember: turn this off
  5. Performed a full shutdown (Shift + Shutdown)
  6. Booted into Ubuntu

Now, the Wi-Fi card is detected properly:'

nmcli device

wlp1s0 wifi disconnected --

And no more probe failed with error -110 in dmesg.

Summary

If your Intel AX200 card isn’t working on Ubuntu and you're dual-booting with Windows, disable Fast Startup in Windows and fully power off the system. The card will reset, and Linux will be able to initialize it properly.

It’s a frustrating issue, but once you know the cause, the fix is pretty simple.
