本人是宽带的安装师傅,有几年的从业经验了,下面将经常遇到的用户宽带问题整理如下:如果没有你说的问题也看看,多了解点宽带方面的知识。
1.宽带问题应先查看光纤猫的los(也称光信号)灯是否闪红灯,闪红灯表示是光纤断了,打运营商的客服电话报修,自己修不了。光纤猫正常的是los灯不亮和pon(网络E)灯长亮。电话线的猫看link(有些猫是adsl)灯亮不亮,不亮则表示电话线不通了,打运营商的客服电话报修.
2.如果猫的相应状态灯正常(外线正常),用网线将电脑直接连接到猫上,点宽带连接拨号,输入正确的用户名和密码(要小写和半角),看是否可以连接成功,连接成功就说明运营商到你家的宽带是没问题的(如果打不开网页就是你电脑的问题,电脑问题很多,可以重装电脑系统一般就好了,电脑店装系统大概30元左右)。如果点宽带连接出现691错误则说明你的宽带用户名或密码错了,打运营商电话可以修改密码。如果是是其他错误代码是你电脑问题(到百度里可以搜到该错误代码的含义及解决方法)。出现错误代码请重新建立一个宽带连接试试(有时宽带连接会损坏)。宽带连接的建立方法百度里也有。
3.使用路由器上网的;猫出来的网线一定要插到路由器的wan口,插路由器其他口则失去了路由器的路由功能(也就是不可以自动上网,电脑不能直接上网但可以通过点宽带连接拨号上网,相当于电脑直接接猫了),电脑的网线插到路由器的1-4口,电脑的本地连接(或无线网络连接)属性里的tcp/ip协议里的iP地址和dns都选择自动获取。观察路由器的wan灯亮了没有(tplink路由器是最右边的像ie浏览器图标样的灯),然后路由器需要正确设置好。不少用户说连了路由器后怎么宽带连接是显示断开的连不上?经过路由器后是通过路由器直接上网的不需要再点宽带连接了。
4.设置路由器;电脑的本地连接(或无线网络连接)属性里的tcp/ip协议里的iP地址和dns都选择自动获取。在路由器通电状态下按住标示为reset键10秒(有些路由器在一个小孔内)进行复位恢复出厂值,电脑打开浏览器在地址栏(输网站地址的地方)输入路由器背面的ip地址回车进入,输入路由器背面的用户名和密码登陆设置界面,用快速设置向导进行设置,选择adsl(pppoe)方式输入宽带用户名密码一步步完成。无线路由器多个设置无线名称(ssid)和无线密码的步骤。各个路由器具体的设置百度有教程。
5.关于本地连接显示受限制的问题;这是因为电脑网卡没有获取到ip地址。如果电脑直连猫的这是正常的,猫不是路由器,它是不给电脑分配ip地址的,这并不影响电脑上网,电脑是通过宽带连接拨号获取ip地址上网的。如果电脑是连的路由器,看看是不是插到路由器的wan口里去了,需要插到其他口(Lan1-4)才是正确的。还有,电脑的本地连接(或无线网络连接)属性里的tcp/ip协议里的iP地址和dns都要选择自动获取。
6.电信、网通、联通、移动、铁通等大部分都是采取adsl(即pppoe)拨号上网方式,广电宽带和部分地区电信采取的没有用户名和密码的宽带是动态ip上网方式。企业的是固定ip上网方式。
有些时候也不知道为什么会出现这种情况,无线网处显示一个小叹号,虽然连上,却无法访问internet。这种情况怎么处理?为什么wifi连接上了却不能上网?
你好 ,请你重新启动电脑测试如果还是这样可能是宽带故障看一下宽带猫的指示灯是否正常如果不正常就可以确认宽带故障直接报障即可
