是否有任何可能的方法来更改Linux中的信标间隔。我有使用ath9k驱动程序的atheros芯片组。我知道可以使用iw命令来设置信标间隔，但我仍然对使用该命令感到困惑。另外我怎么知道当前的信标间隔更改无线信标间隔
我想要的是使用Ubuntu 12.04和低于正常值的信标间隔使两个设备之间的ad hoc网络。
这是我运行iw命令时得到的输出。
iw iwphy2 set beacon-interval 25

You can omit the 'phy' or 'dev' if the identification is unique,
e.g. "iw wlan0 info" or "iw phy0 info". (Don't when scripting.)
Do NOT screenscrape this tool, we don't consider its output stable.
