Wifi doesn't work and PC doesn't have an ethernet port

Postby Mich-C » 2017-06-23 15:40

Hi, I installed Debian 8 stable on my Tablet (dell venue 10)
I can't connect to the internet using the Wifi (and can't connecting a Lan cable...) I tryed using the terminal in different ways and I tryed to install a driver compatible with my hardware but I didn't have good results...

Windows reports these 2 wifi cards for the same tablet (strange)
"Broadcom 802.11 abgn Wireless sdio"
"Dell wireless 5810e Mobile Broadband"


Can anyone tell me the which drivers I need and how can I install them? (I don't care if the drivers are open or proprietary)

Your wireless card Broadcom BCM43241 on SDIO is already supported by Linux 3.16, you probably need the following:
(a) The binary firmware package `firmware-brcm80211`
(b) nvram config file `brcmfmac43241b4-sdio.txt`

You can confirm by `dmesg | grep brcmfmac` right after reboot. You might see "brcmfmac_sdio mmc0:0001:1 firmware: failed to load ...... (-2)" if it's indeed lacking firmware.

The latter, the "txt" can be obtained in various ways. See:

Thanks, the terminal reported that error "brcmfmac_sdio mmc0:0001:1 firmware: failed to load ......"
So I copyed that 2 file files you linked in the right directory (a .bin and a .txt file) and I also installed the package `firmware-brcm80211` for Debian Jessie.
I rebooted, executed the command `dmesg | grep brcmfmac` and rebooted again, but when I open Wicd (wireless tool) I still have "No wireless network found"

It seems that the driver cannot find the nvram config file (the .txt), are you sure you obtained the right file and put it in /lib/firmware/brcm/ ?

Hi orythem27, the first time I didn't copyed the file in the right location (don't know why), now I put the file in that folder and still Wi-Fi doesn't work.
Maybe Debian support for tablet like mine is too weak (Dell venue 10 5055), should I switch to Gallium OS? It's a distro made for chromebooks...

Make sure you have entered the exact command without any typo. e.g. ">&21" is not the same as "2>&1"
