Failed to Detect Network Card[SOLVED]

Post by mistral » Sun Feb 11, 2018 2:36 am

Hi people,

I have installed Linux Mint 18.3 Cinnamon 64bit on tablet Acer Aspire Switch 10 SW5-012-19RC to replace Windows 8.1, which I couldn’t recover. There is a problem; it cannot detect built-in Broadcom 802.11abgn Wireless SDIO Adapter.

Could you help me with this?

Thanks JeremyB, I ran the command. It showed an error:

user@acer ~ $ ls /sys/firmware/efi/efivars | grep nvram; dmesg | grep sdio
nvram-74b00bd9-805a-4d61-b51f-43268123d113
[ 16.525790] brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43241b4-sdio.txt failed with error -2
[ 17.540268] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
[ 18.555612] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50

Then as explained here: https://www.spinics.net/lists/linux-wir ... 34712.html

the following command solved the problem:
user@acer /sys/firmware/efi/efivars $ sudo cp nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43241b4-sdio.txt

Thanks again for your help. Please mark it as solved.
