联想笔记本安装win2016,intel ac3165无线断网联想笔记本默认安装win10系统，由于台式机平时使用的是windows server 2008系统，使用win10很不方便，自带一堆软件，占用资源又高，所以换成了windows server 2016,就是触摸板无法使用，其它正常，由于只能使用wifi网络，所以hyper-v 虚拟机需要通过无线网卡作为网关上外网，就安装了win2016系统自带的 路由与远程访问 功能，配置好后，发现无线网路 每过一段时间就找不开网页，ping 外网的Ip，又是可以ping通，换DNS后，还是一样的问题，最后关闭 路由与远程访问  功能后，恢复正常，由于没时间测试，hyper-v虚拟机上网又只能搞ICS了。

下面是tomcat-8.5.37原生server.xml配置，删除了所有自有注释Connector主要属性：    protocol  监听的协议，默认是http/1.1    port   连接端口号    minThread  初始化线程数    maxThread  最大线程数，生产配置800-1000    minSpareThreads="100" 最大空闲线程    enableLookups="false"  如果为true，则可以通过调用request.getRemoteHost()进行DNS查询来得到远程客户端的实际主机名，若为false则不进行DNS查询，而是返回其ip地址，生产环境建议设置false    redirectPort  指定服务器正在处理http请求时收到了一个SSL传输请求后重定向的端口号    acceptCount="800"  指定当所有可以使用的处理请求的线程数都被使用时，可以放到处理队列中的请求数，超过这个数的请求将不予处理，相当于多线程的队列    connectionTimeout  指定超时的时间数(以毫秒为单位)    SSLEnabled  是否开启 sll 验证，在Https 访问时需要开启&nbs...
