做一个项目，需要点对点通信，进行ad hoc组网。应该是要用的IBSS模式，但是该设备推荐的无线网卡之一intel 7260HMW好像不支持IBSS。下边是一些有用的信息：

从Supported interface modes可以看出没有IBSS模式，是不是意味着不能用这个网卡建ad hoc网络了，只能换用别的网卡？
但是https://communities.intel.com/thread/60677上有人声称在2.4GHz下打开了ad hoc网络，这又是什么原因？因为内核不同吗？
另外有没有前辈用过http://elinux.org/Jetson/Network_Adapters里提到的某个网卡支持IBSS，我可以试一下。
先谢谢大家了。
