路由器不能上网怎么解决
随着电脑和网络的普及,在家上网已经成为司空见惯的事了,有的家庭可能家中不只一台电脑,这时候为了保证家里各个成员都可以上网有一台路由器就是必备的了。但是有的朋友经常因为配置有误而造成路由器产生故障,那么今天就让编辑给你支支招帮您轻松搞定这些问题。
无法浏览网页
故障现象:网页以不能正常打开,但是QQ之类的程序却可以正常运行。
解决方法:要解决这个问题,建议在路由器和计算机网卡上手动设置DNS服务器地址((ISP局端提供的地址),打开路由器设置界面,找到“网络参数”中的“WAN口参数”的字段,然后在下面手动设置DNS服务器地址。另外,在“DHCP服务”设置项,也需要手动设置DNS服务器和备用的DNS服务器地址,该地址需要从ISP供应商那里获取。
无法进行拨号
故障现象:不能进行正常的拨号程序。
解决方法:这种问题的解决方法比较简单,具体做法是:打开Web浏览器,在地址栏中输入路由器的管理地址,如192.168.1.1,此时系统会要求输入登录密码(该密码可以在产品的说明书上查询到),登陆后进入管理界面,选择菜单“网络参数”下的“WAN口设置选项,在右边主窗口中,“WAN口连接类型”选择“PPPoE”,输入“上网账号”及“上网口令”,点击连接按钮即可。
部分计算机无法正常连接
故障现象:路由器硬件上没有问题,所连接的计算机也没有问题,但是却不能实现正常连接,而局域网中的其他计算机可以正常连接上网。
解决方法:先将被绑定MAC地址的计算机连接至路由器LAN端口(但路由器不要连接Modem或ISP提供的接线),然后,采用路由器的MAC地址克隆功能,将该网卡的MAC地址复制到宽带路由器的WAN端口,接着在未被绑定的计算机上进行如下操作:Windows 2000/XP下按“开始→运行”,输入“cmd/k ipconfig /all”,其中“Physical Address”就是本机MAC地址。
