Public bug reported: When connected to a 5GHz (802.11ac) WPA2 wireless network , running UFW firewall enabled , I experience intermittent issues where the Wi-Fi completely disconnects and the 5G network is no longer displayed in the list of Wi-Fi Networks. Toggling the "Enable Wi-Fi" option is required for Linux to reconnect to the network.
The latest A10 firmware version is installed on the laptop. I don't think this is a local network issue , as the 5G network appears to still be up when the machine disconnects from it. Also, I have no custom firewall rules that would cause this behaviour.
