Ok, well in my case I was: - 1. missing the firmware at all as I thought it is not required for this device, but this was quickly resolved, my kernel config is as follows: ares ~ # grep -Hrn "FIRMWARE" /usr/src/linux/.config /usr/src/linux/.config:1541:CONFIG_PREVENT_FIRMWARE_BUILD=y /usr/src/linux/.config:1543:CONFIG_FIRMWARE_IN_KERNEL=y /usr/src/linux/.config:1544:CONFIG_EXTRA_FIRMWARE="brcm/brcmfmac43602-pcie.bin brcm/BCM-0a5c-6410.hcd" /usr/src/linux/.config:1545:CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" /usr/src/linux/.config:3222:# CONFIG_CYPRESS_FIRMWARE is not set /usr/src/linux/.config:3372:# CONFIG_DRM_LOAD_EDID_FIRMWARE is not set /usr/src/linux/.config:3428:CONFIG_FIRMWARE_EDID=y /usr/src/linux/.config:5000:CONFIG_FIRMWARE_MEMMAP=y /usr/src/linux/.config:5009:# CONFIG_GOOGLE_FIRMWARE is not set /usr/src/linux/.config:5408:CONFIG_TEST_FIRMWARE=y
2. The message "Direct firmware load for brcm/brcmfmac43602-pcie.txt failed with error -2" is not an issue in general, such file is related to calibration as per my understanding and is not provided for this device. 3. The message "brcmf_cfg80211_reg_notifier: not a ISO3166 code" might cause or not some issue, but this is probably related to manufacturer based on discussions on Gentoo forum 4. I got confirmation from one Gentoo guy from link referenced in previous post by me that he has the device and it works, but mine still didn't work. The last step I check was network stack app boot and found that both packages are in default runlevel: net-misc/networkmanager-1.6.2_pre net-misc/dhcpcd-6.11.3 Once I disabled dhcpcd (which is anyway auto-started on demand by NetworkManager and that was somehow causing issue and continuous switching of MAC addresses as well) I was able to connect to wifi. Stability - I am on 4.10.3-gentoo kernel and: A. At work/airports - I am on Open or WPA2-PSK secured network and all is fine, I didn't experienced disconnect or Kernel Panic for about 2 weeks B. At home - Well, this is still strange. When I work alone all is stable, but when my wife sit at me and connect from here Android based Lenovo phone, in about less then ~5-30 minutes I get kernel panic. I will try to capture some more details about this strange and probably unique situation as I don't experience it anywhere else. (probably it is because of my wife :-) ) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1600624 Title: MacBook wifi doesn't work (brcmfmac) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1600624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
