 |
|
Hello everyone! I have this BCM4352 Broadcom WiFi card and I can not make it work. I tried to follow this guide:
https://wiki.gentoo.org/wiki/Dell_XPS_13_9343
because this Dell XPS has the same WiFi card, maybe I have done something wrong but mine isn't working, it isn't even recognized by the system.
This is the ifconfig -a output:
| Code: |

The wlp0s20f0u1 is a USB dongle WiFi that I'm using as a temporarily solution, alongside wpa supplicant.
Instead this is the lspci output:

Moreover, this should be my current kernel configuration: http://dpaste.com/2MSV2E2
Kernel version is 5.4.28-gentoo-x86_64
Thank you for your help!

| You skipped a step, because it was colored. It is as I expected. You are lacking the firmware packages. Don't know if you need both, but definitely need the broadcom one. |

| If you don't have a network at this point, and cannot go back to install mode, you could try to manually copy the missing files (those that appear in dmesg with -2 error) to /lib/firmware. Be sure to respect the paths. In your case /lib/firmware/brcm/. |

I do have internet connection, I prefer to not re-install Gentoo. |

You don't have to reinstall. just "emerge net-wireless/broadcom-sta sys-kernel/linux-firmware" and that should be all. |

dmesg still shows those files missing? |

If you use an initrd file you might want to redo that again.
I notice in your previous post of dmesg, it shows 3 different times the kernel tried to load the firmware. One at the point of boot. That might be during initrd time. It should still work though. |

| then add those files to CONFIG_EXTRA_FIRMWARE separated by spaces, or make it a module. |

I have manually added /lib/firmware/brcm/BCM20702A1-0a5c-21fb.hcd downloaded from here https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM20702A1-0a5c-21fb.hcd
Now dmesg | grep -- -2 shows this:

spike32,
Is that from your Gentoo?
| Code: | wlp0s20f0u1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.104 netmask 255.255.255.0 broadcast 192.168.1.255 |
It works well enough to have an IP address, so what doesn't work?
Your missing firmware looks to be for Bluetooth but it might well be shared.
The 2.4GHz band is used by both Wifi and Bluetooth. Indeed, some chipsets share the radio components.
Your dmesg output when you boot your own kernel would be good.
Its big so has to go to a pasetbin site.
If you need to, you can do then post dmesg.txt after you reboot to get networking.
Your kernel BCM43_ is built into the kernel but its firmware is not listed in CONFIG_EXTRA_FIRMWARE=""
The kernel wireless page indicates that your Wifi may not be supported by in kernel drivers.
The output of would be good, so we can see the pci vendor and device IDs for your
| Code: | | 03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter (rev 03) |
There are other drivers but we need to know which chip you actually have. BCM4352 is a bit vague.

spike32,
You need net-wireless/broadcom-sta as mentioned above and its firmware.

The problem is that my wifi card is not even recognised

spike32,
I don't think that your firmware is is the linux-firmware package.
Please put all of dmesg onto a pastebin site.

I think this might be the relevant bit. Although I have no idea what to do next. Seems to me to be a conflict between a less then ideal driver in the kernel, and a better driver outside of kernel which compete for the same resources. Sort of like nouveau & nvidia.
I don't exactly know where this wl module came from, but based on a cursory google reading, seems you have to disable the kernel modules, if you plan to use the broadcom proprietary drivers. so blacklist or disable brcmsmac, bcma and b43.
Now, I wouldn't suggest to actually do that if you have no backup, because I think your removable usb wifi thingy might need 1 or 2 of those. I seen your computer has an ethernet port, so maybe use that instead of your wifi adaptor, and then you can continue to disable those and go with wl alone. Not sure how to proceed at this point. |

spike32,
Lets rewind a little.
You can try wl or broadcom-sta but only one may be loaded at a time.
If you manage to load both, look inthey will fight over the hardware and neither can win.
