Macbook Pro - no wireless interface

I have a unibody macbook pro, trying to get the wireless to work but the wiki seems to have brought me to a dead end.

According to this:

$ lspci -vnn | grep 14e4
02:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5764M Gigabit Ethernet PCIe [14e4:1684] (rev 10)
        Subsystem: Broadcom Corporation NetXtreme BCM5764M Gigabit Ethernet PCIe [14e4:1684]
03:00.0 Network controller [0280]: Broadcom Corporation BCM43224 802.11a/b/g/n [14e4:4353] (rev 01)

I have a BCM43224, which uses the brcmsmac driver. According to the wiki, this driver is included in the kernel and requires no setup at all.

But the wireless interface doesn't come up when I do this:

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether 58:b0:35:fd:07:94 brd ff:ff:ff:ff:ff:ff

I'm not sure what more I should post, but here's the output from hwdetect:

$ hwdetect --show-net
NET    : libphy tg3 bluetooth mac80211 rfkill cfg80211 

I don't know what any of those mean, other than bluetooth

Surely I must be missing something simple if this driver is supposed to "just work", right?

Re: Macbook Pro - no wireless interface

And here's the relevant wiki troubleshooting guide that suggests the blacklisting mentioned in the previous post. I mention this because the wiki also says:

Now, rebuild the initramfs image and everything should work as expected.

# mkinitcpio -p linux

So, I did this and it doesn't seem to have worked. The link that karol pointed to says this:

To see if you were successful, execute

grep bcma /proc/modules

If there is no output, then blacklisting was successful.

But there was output:

$ grep bcma /proc/modules
bcma 11198 0 - Live 0xfb5f5000

So apparently the blacklisting was unsuccessful.

Re: Macbook Pro - no wireless interface

I could be wrong, but I it would work if you rebooted. I am fairly certain that blacklisting only stops modules from getting automatically loaded. If it was already loaded, you'll need to manually unload bcma and then load the module you need.

It should be something like:

$ rmmod bcma
$ lsmod | grep bcma #to check that it did unload
$ modprobe <driver name. Idk what that is. brcmsmac?>

If you can't find the right name of the module, try:

$ rmmod bcma
$ /etc/rc.d/network restart

That might work... try it and let us know?

Re: Macbook Pro - no wireless interface

Ok so I've managed to fix the interface issue. For some reason bcma wasn't being removed at first.

So now I'm trying to use wicd to connect to my network. It detects it, but fails at authenticating and gives me the message "Bad Password", but I'm sure that it's the right one, since it works on Mac OS X. The router is using a WPA2 pre-shared key.

The router has acted up in the past though, so this possibly could be the router's fault. I'm going to try and connect to my university's public internet when I get a chance.
