系统 42.1，，gnome
是网卡不支持还是什么原因？

没人吗？

3

BCM43142 想必用的是私有驱动 broadcom-sta。顾名思义，只支持 STA 模式，不支持 AP 模式
这张卡 ** 目前 ** ** 目前 ** 在 Linux 下无法开启 AP 模式。

4

我安装的是 broadcom-wl broad-wl-kmp-desktop 。。？？这就是 sta 吗？

5

是的，闭源驱动只有一款。

6

好吧，，谢谢了

7

最终换了块无线网卡，intel 大法好 :nauseated_face:

8

事实上用 AP 模式 Atheros 的比较好，Intel 无线网卡驱动 iwlwifi 基本都不支持 AP 模式

9

我有一块无线网卡，DWL-G650M，稳定性非常不错，可是只能用 NdisWrapper 来用 XP 的驱动来使用。请问有没有更好的解决方案呢？系统是 openSUSE 13.2。

10

貌似没有，ath5k 点名不支持 AR5005VL
如果 ndiswrapper “稳定性非常不错”，就无需再折腾其它。

参考
wiki.debian.org/ath5k#Unsupported
wireless.wiki.kernel.org/en/users/drivers/ath5k#supported_chips

看来也只能是维持现状了。NdisWrapper 的稳定性是不错，可是每次都需要手动输入 WIFI 密码才可以连接。我换了一块有点小故障的 USB 网卡，输入一次密码就可以了。

12

找到保存 WIFI 密码的办法了。点 WIFI 图标，然后点扳手图标，然后编辑 WIFI，在安全选项卡里输入密码就可以了。
