1.1.1版本WLAN还是不稳定容易出现掉网或者PING超时

[jampinwang]

SDK更新1.1.1版本后相比1.0.2版本WLAN的带宽吞吐率确实改善很多，用jperf测试很容易超过8MBits，更新以前基本上不会超过5MBits, 但是测试发现在长时间播放在线音乐的过程中容易出现音乐中断的情况或者中途现网络掉线重联的情况。 调试发现基本上可以排除路由器和外网的问题， 直接用电脑PING 872的机器IP 在音乐卡的过程中PING也是超时的（PING不通）。

另外出现掉网自动重连时串口输出了下面的LOG： WAR [CQM] BSS lost. ERR [CQM] Reporting connection loss.

由于这些打印的问题者是原厂打包到wlan的库里面的，麻烦原厂或者其它高手帮忙看看怎么解决！ 感谢！！
