The firmware to be loaded correctly and the WLAN interface to be usable as usual. I tried the packages from stretch-backports (20180825+dfsg-1~bpo9+1) as well as latest firmware blobs from linux-firmare git, but only a downgrade to firmware-brcm80211:20161130-3 allowed the firmware to be correctly loaded. output of 'modinfo brcmfmac': filename: /lib/modules/4.18.0-0.bpo.1-amd64/kernel/drivers/net/wireless/broadcom/brcm80211/brcmfmac/brcmfmac.ko license: Dual BSD/GPL description: Broadcom 802.11 wireless LAN fullmac driver. author: Broadcom Corporation firmware: brcm/brcmfmac4373-sdio.bin firmware: brcm/brcmfmac4356-sdio.bin firmware: brcm/brcmfmac4354-sdio.bin firmware: brcm/brcmfmac43455-sdio.bin firmware: brcm/brcmfmac43430-sdio.bin firmware: brcm/brcmfmac43430a0-sdio.bin firmware: brcm/brcmfmac4339-sdio.bin firmware: brcm/brcmfmac43362-sdio.bin firmware: brcm/brcmfmac4335-sdio.bin firmware: brcm/brcmfmac43340-sdio.bin firmware: brcm/brcmfmac4334-sdio.bin firmware: brcm/brcmfmac4330-sdio.bin firmware: brcm/brcmfmac4329-sdio.bin firmware: brcm/brcmfmac43241b5-sdio.bin firmware: brcm/brcmfmac43241b4-sdio.bin firmware: brcm/brcmfmac43241b0-sdio.bin firmware: brcm/brcmfmac43143-sdio.bin firmware: brcm/brcmfmac4373.bin firmware: brcm/brcmfmac43569.bin firmware: brcm/brcmfmac43242a.bin firmware: brcm/brcmfmac43236b.bin firmware: brcm/brcmfmac43143.bin firmware: brcm/brcmfmac4371-pcie.bin firmware: brcm/brcmfmac4366c-pcie.bin firmware: brcm/brcmfmac4366b-pcie.bin firmware: brcm/brcmfmac4365c-pcie.bin firmware: brcm/brcmfmac4365b-pcie.bin firmware: brcm/brcmfmac4359-pcie.bin firmware: brcm/brcmfmac4358-pcie.bin firmware: brcm/brcmfmac43570-pcie.bin firmware: brcm/brcmfmac4356-pcie.bin firmware: brcm/brcmfmac4350c2-pcie.bin firmware: brcm/brcmfmac4350-pcie.bin firmware: brcm/brcmfmac43602-pcie.bin alias: usb:v04B4p0BDCd*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0A5Cp0BDCd*dc*dsc*dp*ic*isc*ip*in* alias: usb:v043Ep3101d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v04B4pBD29d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v13B1p0039d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0A5CpBD27d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0A5CpBD1Fd*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0A5CpBD17d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v0A5CpBD1Ed*dc*dsc*dp*ic*isc*ip*in* alias: pci:v000014E4d0000440Dsv*sd*bc02sc80i* alias: pci:v000014E4d000043C5sv*sd*bc02sc80i* alias: pci:v000014E4d000043C4sv*sd*bc02sc80i* alias: pci:v000014E4d000043C3sv*sd*bc02sc80i* alias: pci:v000014E4d00004365sv000014E4sd00004365bc02sc80i* alias: pci:v000014E4d000043CCsv*sd*bc02sc80i* alias: pci:v000014E4d000043CBsv*sd*bc02sc80i* alias: pci:v000014E4d000043CAsv*sd*bc02sc80i* alias: pci:v000014E4d0000AA52sv*sd*bc02sc80i* alias: pci:v000014E4d000043BCsv*sd*bc02sc80i* alias: pci:v000014E4d000043BBsv*sd*bc02sc80i* alias: pci:v000014E4d000043BAsv*sd*bc02sc80i* alias: pci:v000014E4d000043EFsv*sd*bc02sc80i* alias: pci:v000014E4d000043E9sv*sd*bc02sc80i* alias: pci:v000014E4d000043D9sv*sd*bc02sc80i* alias: pci:v000014E4d000043D3sv*sd*bc02sc80i* alias: pci:v000014E4d000043ECsv*sd*bc02sc80i* alias: pci:v000014E4d000043A3sv*sd*bc02sc80i* alias: sdio:c*v02D0d4373* alias: sdio:c*v02D0d4356* alias: sdio:c*v02D0d4354* salias: sdio:c*v02D0dA9BF* alias: sdio:c*v02D0d4345* alias: sdio:c*v02D0dA9A6* alias: sdio:c*v02D0d4339* alias: sdio:c*v02D0d4335* alias: sdio:c*v02D0dA9A4* alias: sdio:c*v02D0dA962* alias: sdio:c*v02D0dA94D* alias: sdio:c*v02D0dA94C* alias: sdio:c*v02D0d4334* alias: sdio:c*v02D0d4330* alias: sdio:c*v02D0d4329* alias: sdio:c*v02D0d4324* alias: sdio:c*v02D0dA887* depends: mmc_core,brcmutil,cfg80211,usbcore retpoline: Y intree: Y name: brcmfmac vermagic: 4.18.0-0.bpo.1-amd64 SMP mod_unload modversions parm: txglomsz:Maximum tx packet chain size [SDIO] (int) parm: debug:Level of debug output (int) parm: p2pon:Enable legacy p2p management functionality (int) parm: feature_disable:Disable features (int) parm: alternative_fw_path:Alternative firmware path (string) parm: fcmode:Mode of firmware signalled flow control (int) parm: roamoff:Do not use internal roaming engine (int) parm: iapp:Enable partial support for the obsoleted Inter-Access Point Protocol (int) -- System Information: Debian Release: 9.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.18.0-0.bpo.1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) firmware-brcm80211 depends on no packages. firmware-brcm80211 recommends no packages.
