wifi已连接不可上网有可能是手机的DNS问题、路由器不稳定、宽带出现故障、路由器未联网、宽带欠费等原因,所以下面小编就来跟大家说说wifi已经连接不可上网是什么原因的介绍。
一、手机的DNS出现问题
如果其他设备连接在同一个WiFi却可以上网,则可能是手机的DNS问题。
解决方法:我们先在手机的设置中选择长按连接的WiFi选项,选择【修改网络】-【显示高级选择】,进入后把IP设置为静态,拉到下面设置域名,比如设置为【8.8.8.8】保存;如果依旧无法上网,可以在长按WiFi的时候选择删除忘记这个WiFi设置,然后再重新连接输入密码后上网。
二、路由器不稳定的问题
有些无线路由器、光猫(宽带猫)的质量比较差,长时间运行后会出现死机等一系列的问题。
解决方法:把这些无线上网的无线路由器、光猫(宽带猫)断电,等待几分钟后再接通电源,启动设备。待正常启动后,再连接wifi测试下是否可以正常使用了。
三、宽带出现故障的问题
如果之前的wifi是可以连接上网,突然就出现了无法上网的这个问题。并且已经把路由器、猫断电重启了仍然无法使用的话,那么就可能是宽带线路出问题了,或者是宽带欠费了引起的。
解决办法:首先拨打宽带的客服电话,查询下是否是因为宽带欠费导致的。如果是欠费就补交费用。如果未欠费,可以转接到人工客服,进行故障申报,让运营商安排工作人员维修。
四、路由器未联网的问题
如果宽带线路没有问题,宽带也没有欠费,并且宽带运营商不负责调试路由器。那么检查路由器中的相关配置。可以用电脑或者手机,先登录到路由器的设置页面,找到并打开上网设置 或者WAN口设置的选项,就可以看到路由器的联网状态信息了。
如果此时路由器中显示联网失败 ,那么请仔细阅读下面这部分的内容,如果显示联网成功,那就可以正常上网了。
1、检查线路连接
普通的网线路由器上有1个WAN接口,4个LAN接口(有的路由器只有2个或者3个LAN接口),请按照下面的方法进行正确的线路连接。
1)、路由器上的WAN接口,需要用网线,连接到猫的网口。如果你家的宽带没有用到猫,则需要把入户的宽带网线,插在路由器的WAN接口。
2)、如果家里有电脑,需要用网线连接到LAN接口,任意一个LAN接口都是可以的。
2、检查上网方式
路由器中的上网方式(有的路由器中叫做:联网方式、连接类型、WAN口连接类型 等),如果设置错误,就会造成路由器联网失败,即连接wifi后不能正常使用。
被限制连网了:几乎所有的网线路由器中,都有一些功能,可以用来限制手机、电脑连接wifi上网。如果手机、笔记本电脑被限制了,那么连接wifi后就会出现用不了的问题。要是对路由器比较熟悉,那么我们就可以登录到路由器的设置页面中,找到无线MAC地址过滤、网线设备接入控制、上网控制、家长控制等功能,并进行关闭即可。
以上便是wifi已经连接不可上网是什么原因的介绍,希望能帮到大家。
