Atheros AR9462 - Unabe to re-connect to network after disconnecting until reboot.

Post by DirtyDavis69 »

I have searched high and log since release of Linux Mint 20 but have not found a resolution.
I am having issues re-connecting to WiFi and tethered networks after disconnecting.
I can re-connect to a network, and I get the notification that a connection was established, but I cannot ping for example Google's DNS server and all apps are unable to connect.
  • I will disconnect for the first time, and will not be able to connect again until I reboot.
  • The issue appears to impact USB tethering as well. After a single disconnect while tethered, a full reboot is required to restore network connectivity.
  • I also notice that any Bluetooth device will lag terribly once I connect to a WiFi network, and this issue has rendered Bluetooth inoperable while on WiFi, which is pretty much all the time as this is a laptop.
  • I am able to USB tether, while connected to WiFi, and disconnect from WiFi after the USB connection is established and I will remain connected./list]


    This issue has happened since updating from Mint 19.3 to 20.
    I have tried:
    • Many many different commands I found online, such as modprobe. So many that I reformatted as I had butchered the system entirely.
    • Reformatting and doing a clean install and the issue persisted.
    • I then tested the issue in the live image and the WiFi/Bluetooth issues are happening there too.
    I believe all of this is tied to Atheros ATH9K, and potentially the kernel as well.
    Any assistance is greatly appreciated.
