电信光猫宽带灯不亮，其他灯都正常，上不了网，这是怎么回事，如何解决？
推荐回答（5个）
第一、检查网线有没问题。有的是水晶接头不好。
第二、直接用光猫连接电脑拨号试试。如果可以说明猫没问题
第三、接上路由器，重新设置下在登陆试试
还有就是今天刚装的。你要拨打客服咨询下你们的宽带目前是不是正常的服务状态。如果正常就没问题。
宽带猫
宽带通过调解成为光猫
宽带猫
MODEN即调制解调器，计算机之间通过电话线进行通信的设备。调制解调过程：数字信号变为模拟信号-->传输-->模拟信号变成数字信号。 Moden有外置式和内置式，内置式也称Moden卡，一般是PCI接口。也叫ADSL.。一般情况下，只要你在电信注册网络服务，某省份除外。
电信会送一个猫给你。ADSL的设置不是很难，只要按照说明书上的方法步骤去装就可以了。现在市场上的“猫”基本都是直接装，直接用，不需要再另外设置的。华为MT800-B上市已久现华为公司另有新款，今年的市价一直停留在120元左右。
近日为争夺国庆市场，有商家将该款产品以48元低价甩卖。想购买ADSL MODEM（宽带猫）的用户别错过了。MT800采用纯白色塑料外壳设计，机身分布众多散热孔，散热的同时也兼做装饰功能，是一款精巧美观、设计经典的ADSLADSL MODEM。
它提供一个以太网接口，内置话音分离器，给用户接入Internet同时接电话机提供了方便。这款ADSLModem外观虽然小巧，但是功能完善。
它的上行速率是896Kbps，下行8Mbps,支持路由、桥接方式，支持NAT(NAPT)和DHCP SEVER，支持Bridged Ethernet over ATM (RFC 1483)、Classical IP over ATM (RFC 1577)、PPP over ATM protocol (RFC 2364)、PPP over Ethernet (RFC 2516)协议）目前市场上面还有俗称4口猫和相框猫的有好多牌子都在推广下行速率最大可达15M且不会掉线。
并且内置隔离防火墙功能，支持强大的IDS和IP地址过滤功能，有效防止网络黑客攻击，这对于组建小型网络的用户而言可谓是非常的实用。目前电信大力推广一款以FTTH光纤到户或FTTB类型，以前用的ADSL形式的猫已逐渐淘汰了，光纤宽带具有网速快而稳定现走在全国的最前端，E8-C的猫也称为光猫目前有华为HG8245和中兴F401和F420无需用户自己购买都是电信送的，有的省份交押金2年后返还给用户。
