I'm having problems getting wireless working. When I try the brcmsmac driver, I get nothing. No SSID, nothing.

Even when I switch hwmode to '11n', it still does not work.

When I try the brcmsmac driver, I get the following error message:

"Unsupported bus type..." and error -22. And yes, I've uninstalled b43

What can I do?

I need wireless-n support!

Check your wireless chipset and read a bit about available WiFi drivers:
https://wikidevi.com/wiki/ASUS_RT-N66U
http://wiki.openwrt.org/doc/hardware/so … fi_drivers

I've tried that, I've even installed nas. But it still gives me that error.

I know the RT-N66U uses the BCM4331. I can't use bcmsmac or b43 because I need 5ghz support.

The 'wl' and 'ilc' configuration tools can't even find the device.

But it is being recognized:

Per wl_glue.c, seems like the probed bus type does not match what it's expecting:

if (dev->bus->hosttype != BCMA_HOSTTYPE_SOC)
    {
        pr_err("Unsupported BCMA bus type %d\n", dev->bus->hosttype);
        return -EINVAL;
    }

Seems like the pci fixing the kernel is doing during boot is screwing with the bus type and/or PMU config.

Is there a way to disable pci device fixups on a per-device basis?

Any tips?

So read again OpenWrt wiki page about broadcom-wl & BCM4331.

I have now, and I'm getting closer:

[   11.680000] wl: module license 'unspecified' taints kernel.
[   11.690000] Disabling lock debugging due to kernel taint

[   11.850000] Memory leak of bytes 20

and here is my network config:

config wifi-device 'wl0'
    option type 'broadcom'
    option disabled '1'

config wifi-device 'wl1'
    option type 'broadcom'
    option disabled '0'
    option channel '161'
    option hwmode '11n'
    option txpower '16'

config wifi-iface
    option device 'wl1'
    option network 'lan'
    option ssid 'xyz'
    option key 'blah'
    option mode 'ap'
    option encryption 'psk2'

do I need to specify the pci device id path(s)?
