TP-LINK TL-WR842N在线问题

1.尊敬的客户:
您好!

网络掉线可能的原因很多。宽带本身异常、内网病毒攻击，网络中某一个设备或网线故障等等都可能导致网络出现掉线情况。

1、请把路由器升级到最新的131119的版本，升级程序的下载链接：http://service.tp-link.com.cn/detail_download_1299.html

2、如果升级后，问题仍然没有解决，掉线时，如果电脑可以登录路由器界面，请将此时系统工具——系统日志界面信息完整的复制一份发给我们看下；

3、如果掉线时，电脑无法打开路由器管理界面：

1）请确保路由器本身工作正常。可通过路由器指示灯判断路由器工作状态；

2）排查内网是否存在病毒或者恶意攻击，如ARP欺骗等。可尝试在电脑和路由器上做双向IP/MAC地址绑定；ARP绑定的方法可参看链接的文档：http://service.tp-link.com.cn/detail_article_101.html

3）如果是无线掉线，请确保信号质量比较好，同时尽量避免无线干扰。

按上述方法操作，问题还是无法解决的，请您把路由器底部标识的S/N码提供给我们。
