I'm experiencing the same behavior with Ubuntu 20.04 on an older laptop with a Dell/Broadcom BCM43228 NIC. Kernel is 5.4.0-52-generic. Below is an example from syslog. Periodically the WiFi just stops working and takes a long while to resume again. Anyone have any tips from troubleshooting/fixing??
