Networking was on but it said ‘no network devices available. This driver is packaged for the Debian 9 "Stretch" release as broadcom-sta-dkms.After dual-booting MacBook Air with Ubuntu, when I logged in to Ubuntu, I found that Ubuntu did not detect any wireless network. See bugs reported on this package in the Debian Bug Tracking System. Laptop-mode-tools: set WIRELESS_BATT_POWER_SAVING=0 within /etc/laptop-mode/conf.d/nf This may be resolved by disabling power management via: Frequent disconnections can be experienced.This prevents use of any Ethernet device supported by b44.The Sonics Silicon Backplane driver (ssb) conflicts with the wl driver ( 545388).ī44, b43, b43legacy and ssb are blacklisted by default as of broadcom-sta 5.10.91.9.3-3 (brcm80211 and brcmsmac since 5.100.82.38-1, 5.100.82.38-2 respectively).

(Optional) Check all the built DKMS kernel modules. (Optional) Rescue if install/build fails in previous step # apt-get install -f DKMS will build the wl module for your system. This will also install the recommended wireless-tools package. # apt-get install linux-image-$(uname -r|sed 's,*-*-,') linux-headers-$(uname -r|sed 's,*-*-,') broadcom-sta-dkms Install the relevant/latest linux-image, linux-headers and broadcom-sta-dkms packages: # apt-get update The BCM4311, BCM4312, BCM4321, BCM4322 and BCM4331 chips are alternatively supported by the open source b43 driver.Īdd a "non-free" component to /etc/apt/sources.list for your Debian version, for example: # Debian 9 "Stretch"ĭeb stretch-backports main contrib non-freeĭeb buster-backports main contrib non-free The BCM4313, BCM43224 and BCM43225 chips are alternatively supported by the open source brcmsmac driver. The driver depends on the x86 or x86-64 architecture (Debian i386 and AMD64 ports respectively). Supported devices are listed at the end of this page. It includes a binary-only component targeted for the x86 or x86-64 architecture. The proprietary Broadcom wireless LAN driver (wl, aka broadcom-sta) provides support for some Broadcom-based PCI/PCIe hardware. ![]()
