imx6ul WIFI热点连接很慢，手机连上需要2分钟左右

Augustus007

按照手册上配置了wifi热点，手机去连接wifi热点时，大概花了2分钟才连接成功，
即便连接成功后，在使用的过程中也出现断掉wifi连接的情况。

大家有没有遇到过这类情况，有什么办法可以优化wifi连接时间呢

谢谢！

你好，请问您外接wifi天线了吗？推荐您连接两根2.4G的天线

没有外接天线，使用WIFI模块的内接天线。WIFI信号都是满的

经过实际测试，在iPhone上连接imx6ul上的wifi热点，需要花1分钟左右时间；
但是在wifi刚刚开始连接时，我在串口中去ping手机端IP是能够ping通的，
但手机端wifi连接状态却要等一分钟才会在wifi热点名称前打上勾完成连接。

之前尝试去修改hostap.conf和udhcpd.conf配置文件里面的参数，没有作用。

您使用的是linux3.14.38还是linux4.1.15，wifi热点功能测试过，没有出现过需要两分钟才能连接上的情况，是不是有其他的设备影响呢

我也遇到了同样的情况，I.MX6UL开发板，linux 3.14，
iPhone连接大约需要1分钟
