部件号：WL1835MOD 大家好，
这是该 员额的延续。
我们测试了以下建议：
1.您能否确认wlan_EN在cmd 'ifconfig wlan0 down '后被取消断言，并在cmd 'ifconfig wlan0 up '后重新断言？
是的，使用`ifconfig wlan0 down`时，wlan_EN被取消断言，使用`ifconfig wlan0 up`时重新断言。 当WiFi正常工作时，此功能有效。
2. 您是否可以降低DTS文件中的SDIO最大clk频率( Ex 5 MHz)并重新测试
时钟频率已更改为建议值。
3. 请使用最新固件： https://git.ti.com/cgit/wilink8-wlan/wl18xx_fw/log/
使用最新固件(8.9 ．0.0 ．88时)。
WiFi被阻止时，我们仍然遇到相同的问题，重新启动WiFi 的唯一方法 是重新启动整个设备(关闭/打开电源)，这样WiFi才能正常工作。 我们希望就如何解决这个问题提出更多的建议。 附件是所用的WIFI.DTS以及一些错误日志。
