最近更新了D-Link 615 C2的固件到最新版本的DD-WRT，却发现无线部分无法工作，页面提示”Radio is off”，大概就是说广播已经关闭，通过telnet登录到路由，使用ifconfig命令，却没有发现无线网卡，只有eth1,2,br等。通过搜索，发现DD-WRT官方这么一段话：

It is possible that after DD-WRT firmware is installed on DIR-615 Rev. C2, all wireless functions are disabled.

Status panel will state that “Radio is off”, staying like this despite any modifications made on router’s parameters.

Not even line terminal commands (such as “~ # wl radio”) seems to bring back wireless functions online.

Some users reported enabling “Clone WAN MAC” under setup settings may solve the issue (at least 2 cases confirmed).

此处省略千百万字…最后一段话是关键，意思是你得克隆MAC才可能解决此问题。于是照做。

1.克隆MAC。点击应用后，我发现wireless部分的mac地址发生改变？！奇葩，DD-WRT官方历经那么多版本居然没解决这个bug?应用后你就会发现此时无线已经开启。

克隆MAC

2.复查下，telnet中使用ifconfig发现多了一个ath0接口。此接口就是无线部分。
