It appears I have a proper WiFi driver, but for some reason I also have ssb kernel module that I thibk prevents me from having a working WiFi on this laptop...
I currently have a wired connection here. But I want WiFi to be working as well...
Thank you. |

ONEEYEMAN,
I see you have posted multiple times in an effort to get this card working:
https://forums.gentoo.org/viewtopic-t-1171887-highlight-bcm4312.html
https://forums.gentoo.org/viewtopic-t-1145172-highlight-bcm4312.html
https://forums.gentoo.org/viewtopic-t-997980-highlight-bcm4312.html
Your initial post (the last link) about the BCM4312 was in 2014.
At that time you posted:
| Code: | lspci -vnn -d 14e4:
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) |
It seems over the years that nothing you have tried has worked.
Have you considered the broadcom-sta driver:
https://packages.gentoo.org/packages/net-wireless/broadcom-sta
Broadcom's IEEE 802.11a/b/g/n hybrid Linux device driver
Driver . . . . . . . . . . . . . . . Description
brcm80211 . . . . . . . . . . . . . . . Kernel driver mainline version (recommended)
b43 . . . . . . . . . . . . . . . . . . . . . Kernel driver reverse-engineered version
broadcom-wl . . . . . . . . . . . . . . Broadcom driver with restricted license*
Source: https://wiki.archlinux.org/title/Broadcom_wireless
*Obviously, you would have to be willing to accept the license.
I cannot say whether or not it would work with your card -- I do not know. If you decide to try it, when you install that package, pay attention to the portage package warnings. It may give you kernel configuration and module blacklist warnings. For example:
| Code: | MAC80211: If you insist on building this, you must blacklist it!
* PREEMPT_RCU: Please do not set the Preemption Model to "Preemptible Kernel"; choose something else.
* CONFIG_PREEMPT: should not be set. But it is. [ !! ] |
You can adjust your kernel config and rebuild as you deem necessary.
Also, looking at the ebuild, you likely need to blacklist some of the other conflicting kernel modules B43, BCMA, and SSB:
| Code: | ERROR_B43="B43: If you insist on building this, you must blacklist it!"
ERROR_BCMA="BCMA: If you insist on building this, you must blacklist it!"
ERROR_SSB="SSB: If you insist on building this, you must blacklist it!" |
If all else fails, you might consider investing in a USB Wi-Fi Adapter with a chip that is well supported by the Linux kernel and works out of the box with very little additional configuration needed, such as an Intel AX210 for example. I mention that one simply because I have a laptop with that card and it is plug and play (when used with generic kernel or gentoo-kernel-bin). There are likely other viable options. |
