问题

连接wifi时，出现了一个虚假的wifi名为（NVRAM WARNING ERR=0X10），上网查了一下可能是没有写合法的MAC地址。这个warning，是mtk提示您写合法的mac地址。

代码分析

NVRAM WARNING ERR=0X10 原因是没有写合法的MAC地址。这个warning，是mtk提示您写合法的mac地址。

nvram warning,WIFI时有个解决提示 NVRAM WARNING ERR=0X10的信号项，其实这个是WIFI的mac地址错误警告，是由于NVRAM里面没有固定的MAC地址造成的错误提示，这个时候系统会随机生成一个MAC地址，不影响使用，但是对于某些需要开启mac地址过滤的用户来说是一个麻烦的事情，因为mac地址每次都会自动变更，导致无法针对MTK的机器进行过滤。
