How do i activate the brcmsmac in /etc/config/wireless on a asus rt-16n ?

I have installed kmod-brcmsmac ( reboot) and tried this config, it is not working ?? an i missing something =?

config wifi-device 'radio1'
        option type 'brcmsmac'
        option txpower '20'
        option country '00'
        option channel 'auto'

config wifi-iface
        option device 'radio1'
        option network 'lan'
        option mode 'ap'
        option key '********'
        option ssid 'TMP2'
        option encryption 'none'

I too am interested in running brcmsmac on a bcm47xx router (Linksys E3000v1 running openwrt-e3000_v1-squashfs-r38898.bin). The only instructions in the wiki for brcmsmac state to enable it with opkg (and disable all other drivers). I have followed these instructions, but the result appears to be broken in the following ways:


The 2Ghz radio is still using the b43 driver, and will no longer come up. The 5Ghz radio is no longer recognized at all. iw phy doesn't even see it.

root@E3000:~#  lspci -k

    Subsystem: Broadcom Corporation BCM4322 802.11bgn Wireless Network Controller
    Kernel driver in use: b43-pci-bridge

There are still many b43 files scattered all over the file system.

My config/wireless file looks like this:

config wifi-device 'radio0'
    option type 'brcmsmac'
    option channel '11'
    option hwmode '11g'
    option path 'bcma0:0'
    option disabled '0'

config wifi-iface
    option device 'radio0'
    option network 'lan'
    option mode 'ap'
    option ssid 'OpenWrt'
    option encryption 'none'

config wifi-device 'radio1'
    option type 'brcmsmac'
    option channel '11'
    option hwmode '11g'
    option path 'pci0000:00/0000:00:01.0/ssb0:0'
    option disabled '0'

config wifi-iface
    option device 'radio1'
    option network 'lan'
    option mode 'ap'
    option encryption 'none'
    option ssid 'OpenWrt5'

I would love to see more documentation on how to activate the different drivers for bcm47xx hardware. Happy to give more info about my setup.

Here is what I have done:

opkg update
opkg install kmod-brcmsmac
opkg install kmod-brcmutil

rmmod b43
rmmod b43legacy
rmmod wl
rmmod brcmsmac
rmmod brcmutil
modprobe brcmsmac

# make sure to delete the old config files ... you have to ...
rm -f /etc/config/wireless
wifi detect > /etc/config/wireless
vi /etc/config/wireless


Now comment out # "option disabled 1"


My configuration looks like:
root@OpenWrt:~# cat /etc/config/wireless
config wifi-device  radio0
    option type     mac80211
    option channel  11
    option hwmode    11ng
    option path    'bcma0:0'
    option htmode    HT20
    list ht_capab    GF
    list ht_capab    SHORT-GI-20
    list ht_capab    SHORT-GI-40
    # REMOVE THIS LINE TO ENABLE WIFI:
    # option disabled 1

config wifi-iface
    option device   radio0
    option network  lan
    option mode     ap
    option ssid     OpenWrt
    option encryption none
 



After this, run:
wifi



And you should see OpenWrt on your laptop ...
