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.
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 . broadcom bcm94313hmg2l driver

The kernel recognizes the PCIe device and loads brcmfmac . For this card (PCIe variant), you actually need
Only if you get it for free or under $5. For the same Mini PCIe slot, a Realtek RTL8821AE or an Intel 7260HMW offers dual-band 802.11ac and far better driver sanity.
If you’ve recently salvaged a Wi-Fi card from a low-end Windows laptop or purchased a “dual-band 802.11n” mini PCIe adapter on a budget, you might have encountered the .
