The kernel recognizes the PCIe device and loads brcmfmac .
# Check your device ID lspci -nn | grep Broadcom Manually fetch the firmware (Debian/Ubuntu example) sudo apt install firmware-b43-installer Or copy the blob from a Windows driver extraction sudo cp brcmfmac4313-pcie.bin /lib/firmware/brcm/ broadcom bcm94313hmg2l driver
At first glance, it looks promising: 2.4/5 GHz support, decent Linux compatibility on paper, and a cheap price tag. But getting this specific chipset (BCM4313) to play nicely—especially outside of a pure Linux environment—can be surprisingly painful. The kernel recognizes the PCIe device and loads brcmfmac
Broadcom uses different firmware blobs for the 4313 depending on whether the card is connected via SDIO or PCIe. For this card (PCIe variant), you actually need brcmfmac4313-pcie.bin . it looks promising: 2.4/5 GHz support
