 |
|
I am new to Gentoo, and this is the first time I have installed it on my Dell Precision M4800. I have Broadcom BCM4352 wifi but I cannot get Wi-Fi to work. I have tried configuring the kernel a couple of times and have even.then I havent been very lucky.
I see my card when i use lspci -k:
| Code: | 03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter (rev 03)
Subsystem: Dell BCM4352 802.11ac Wireless Network Adapter
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma, wl
|
But when I try ifconfig this is the reply:
| Code: | eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.10 netmask 255.255.255.0 broadcast 192.168.1.255

This is the output of dmesg:

Any help would be greatly appreciated. I am new to Gentoo and I am very excited to learn through this OS. Thank you
Edit: I just had to disable B4xxx drivers that were conflicting.

Plz try
| Code: |
emerge -av broadcom-sta linux-firmware
rfkill list ### to check if wifi is blocked
|
If it still doesnt work then try if it works when you boot into a livecd.
If it does then it is a kernel and/or initrd thing.
In that case emerge
gentoo-kernel-bin
and see if it works.
If yes then you will have to work on your kernel .config

| Are you expecting that ifconfig should show the wireless device? Remember that a bare ifconfig does not show interfaces that are down. It's possible that your wireless interface is working, but you never configured a client for it to acquire an address and bring the interface up. If you still need help, please show the output of ip a and tell us what wireless client you are using. wpa_supplicant is popular. |
