 Posted: Sun Jan 31, 2016 11:56 pm Post subject: Broadcom Wireless Not Working on v4 Kernel |
 |
|
Recently I upgraded from the v3 to the v4 kernel. In each of the v4 kernels I tried (4.0.5, 4.1.12, 4.4.0-r1) I was unable to get my Broadcom wireless to work. Conversely, it has always worked fine for me in the v3 kernels (3.8.13, 3.12.13, 3.16.5). Recently, I rebooted into the 3.12.13 kernel, without rebuilding any modules or packages, and my wireless continued to work.
LedBox ~ # lspci | grep Broadcom
0d:00.0 Network controller: Broadcom Corporation BCM43228 802.11a/b/g/n
.conf file for 3.12.13 kernel: https://bpaste.net/show/41d13b0debd8
.conf file for 4.4.0-r1 kernel: https://bpaste.net/show/fcb9b04bcc4d
make.conf: https://bpaste.net/show/8c004d83c052
iwconfig: http://dpaste.com/0Y546YY
ifconfig: http://dpaste.com/3RV5DE3
emerge --info broadcom-sta: http://dpaste.com/2629ZDE
Thanks for your help and continued support of Gentoo. |

| See what happens to firmware loading (dmesg). Maybe a new version of firmware is required. |

| Never had any of those Broadcoms myself. What it looks like with working kernel (dmesg). |

| Try building the b43 driver as a module. When it is built into the kernel blacklist cannot block it. |

[ 0.609549] b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 9, Type 4 (N), Revision 16)

This PHY type is supported on at least kernel 4.3. Check you kernel config, you need to
enable CONFIG_B43_PHY_N ("Support for N-PHY (the main 802.11n series) devices").
Best you enable all CONFIG_B43_PHY_* options and recompile the kernel. |

Wireless problem is solved and working!
Per jburns, built b43 as a module, but that still didn't clear the problem. Followed roarinelk's advice and enabled as many of the CONFIG_B43_PHY_* options as I could, while keeping b43 as a module. Wireless is working perfectly now.
Resulting .conf file for 4.4.0-r1 kernel: https://bpaste.net/show/399c6a4c6d14
Thanks for all of the advice, very much appreciated. |
