Public bug reported: Device ID: Network controller [0280]: Broadcom Inc. and subsidiaries BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 03)
WiFi worked correctly in Ubuntu MATE 20.04. Now I'm getting very slow throughput and constant error messages like the following: b43-pci-bridge 0000:03:02.0: swiotlb buffer is full (sz: 2390 bytes), total 0 (slots), used 0 (slots) It sounds like this may be related to errors introduced in b43-fwcutter 1:019-5 with installing the wrong firmware, as reported in Debian bugs #958566 and #960279.
