I still have the issue with the latest version of the linux-firmware package (1.173.1). However the firmware (brcm/brcmfmac4356-pcie.bin) in the official linux-firmware repository solves my issue.
The fix was introduced in the following commit: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=fe4a9d49d44c40a7bc32cdd9529e6a5c8ac92519 Regards, Jean-Pierre. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1772624 Title: Broadcom BCM4356 wifi chipset firmware is not working Status in linux-firmware package in Ubuntu: Confirmed Bug description: Hello, After upgrading to Ubuntu 18.04 I got an issue with the wifi chipset (Broadcom BCM4356) not initializing properly.
