无线网卡bcm4321，hostapd起不了，各位帮忙看看.

网卡情况：

lspci | grep Network
00:0c.0 Network controller: Ralink corp. RT2561/RT61 rev B 802.11g
02:00.0 Network controller: Broadcom Corporation BCM4321 802.11b/g/n (rev 01)

lspci -vnn | grep 14e4 
02:00.0 Network controller [0280]: Broadcom Corporation BCM4321 802.11b/g/n [14e4:4329] (rev 01)

安装驱动：

sudo yaourt -S broadcom-wl

至此ip link 已可显示接口wlp2s0。继续激活网卡：

ip link set dev wlp2s0 up
ip addr add 192.168.10.2/24 broadcast 192.168.10.255 dev wlp2s0

ifconfig的情况：

wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.10.2  netmask 255.255.255.0  broadcast 192.168.10.255
        inet6 fe80::218:39ff:fe5c:5543  prefixlen 64  scopeid 0x20<link>

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

hostapd.conf:

cat /etc/hostapd/hostapd.conf
ssid=YourWifiName
wpa_passphrase=Somepassphrase
interface=wlp2s0
#bridge=br0
auth_algs=3
channel=7
driver=nl80211

logger_stdout=-1
logger_stdout_level=2
max_num_sta=5
rsn_pairwise=CCMP
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP

到运行hostapd这总是报错，谁帮忙找找原因？谢谢:

Re: 无线网卡bcm4321，hostapd起不了，各位帮忙看看.

不好意思。我其实有两块无线网卡、初初 iw list 时看到支持AP，其实是另一块 RT2561/RT61 支持AP的。而我发问的这个是没支持的。（手机翻屏不容易啊）
而我有测试过RT2561 ，也是同样的错误提示。我RT2561 用的驱动是linux-firmware，现在要重新考虑驱动问题了。
谢谢百合提供的线索。

奇怪的是查了官网14e4:4329 这个芯片是支持AP的啊。
