UPDATE Kernel 4.1.2-2 and lost Wifi-Connection

Hi everybody...
Yesterday I updated my notebook to 4.1.2-2 Kernel, but when I restarted the pc, the wifi was lost.
If I write the command:

ip link

The result is:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s29f7u1u2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 80:49:71:0f:7c:26 brd ff:ff:ff:ff:ff:ff

The enp0s29f7u1u2 is my Ethernet, but the wlan0 is lost.

And if I use this:

[skioda86@Arch-MacOSX:~]$ lspci -v

02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
        Subsystem: Apple Inc. AirPort Extreme
        Flags: fast devsel
        Memory at a0400000 (64-bit, non-prefetchable) [disabled] [size=16K]
        Capabilities: <access denied>
        Kernel modules: bcma

How I can resolve?

I had the same issue.

Have you read this?

https://wiki.archlinux.org/index.php/Broadcom_wireless

I just rolled back the kernel so I could get online...not sure what kinds of long-term solutions there are for this.

If anyone has any other suggestions to deal with the wonderful world of Broadcom, I would love to hear about it...

I had the same issue. What worked for me was to install broadcom-wl-dkms from AUR.

Hope it helps.

What is the PCI ID of this card?  Which driver were you using, b43?  If so, did you update b43-firmware from the AUR?
