    Question Wi-Fi Adapter Not Recognized on Ubuntu 22.04 - Qualcomm Atheros QCA6174

    Hi everyone,


    I'm having a frustrating issue with my Ubuntu 22.04 system where my Wi-Fi adapter is not being recognized, and I can't connect to any Wi-Fi networks. Here's a summary of the problem:
    System Information:


    • OS: Ubuntu 22.04
    • Wi-Fi Adapter: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter
    • Driver: ath10k_pci
    • Current Firmware: WLAN.RM.4.4.1-00157-QCARMSWPZ-1

    Problem Description:


    • The Wi-Fi adapter appears as DISABLED when I check using lshw -C network.
    • The device status shows unmanaged in nmcli device status.
    • When I try to scan for Wi-Fi networks using nmcli device wifi rescan, I get the error: "Error: Scanning not allowed while unavailable."
    • I've tried using rfkill to unblock Wi-Fi, but it doesn't solve the issue. rfkill list shows that Wi-Fi is not blocked.
    • The adapter was previously working when I was setting up a Wi-Fi hotspot using hostapd. After that, I couldn't connect to any Wi-Fi network.

    Steps I've Tried:


    1. Reinstalling NetworkManager: Ensured NetworkManager is installed and up to date.
    2. Reloading the driver: Tried modprobe -r ath10k_pci and modprobe ath10k_pci to reload the Wi-Fi driver.



    I'm out of ideas at this point. Has anyone encountered a similar issue or could suggest further troubleshooting steps? Any help would be greatly appreciated!


    Thanks in advance!
