出现这种情况就是设置问题，无线网络可用，只是开启了无线功能，电脑可连到路由，无法说明什么问题。
说白了就是一句话，没有连接到外网，使用路由器是不需要电脑来进行宽带拨号连接的，要做的是把宽带帐号密码设置到路由器里面，由路由器来自动完成你以前在电脑进行的宽带拨号连接的动作。
如果无线网络可以上网，那么说明你台式机本身的设置有问题，看一下台式机是不是自动获取IP的还是使用固定IP的。
192.168.1.1路由器设置：
电脑和原网线之间不直接连接，而是通过另一根网线连接。
路由器设置网址，地址栏输入“192.168.1.1”进入到下面这个页面，输入用户名和密码。
-
用户名和密码默认都是admin.输入后进入到“下一步”，如果是宽带上网，选择“ADSL虚拟拨号”，并填写相应的用户名和密码。
-
选择“无线参数”---“基本设置”设置如下。
无线密码的设置，记得一定要填上密码，并记住密，以后就可以无线上网了。
-
电脑的本地连接设置Wn7
-
xp
-
首先按照说明书将网线连接到路由器的WAN口，然后用网线将路由器的LAN口与电脑连接。打开电脑，打开IE浏览器，在地址栏输入192.168.1.1或者192.168.0.1，输入帐号和密码admin（都一样）
进入路由以后选择设置向导，然后
①选择ADSL PPPoE连接，路由器wan口输入你的账户和密码，②如果是带路由功能猫或光猫,(略)③如果是电信的静态IP就选静态连接，一般都是给帐号和密码的；然后保存！
保存后看下路由器运行状态wan口是否获取ip地址，再试试电脑是否能够打开网页，如果连接正常后再进路由器设置无线部分功能，
最后记得每一步都要保存并且最后要在路由器设置中重启一下路由器。
如出现无法连接宽带问题，您可按以下操作处理：
1、进行单机拨号，如有使用路由器，请暂时断开路由器测试；
2、检查网线或电话线是否松动；
3、检查Modem等网络设备是否过热，重启后再试；
4、建议您对电脑进行全盘的病毒扫描。
猫的灯不亮，要么是接错线，要么是网线或接头有问题。？路由是进192.168.1.1设置的，输入宽带账号密码，由路由进行宽带连接，所以电脑不用宽带连接了，直接就能上网。你还是仔细看看说明书吧！你应该操作有错，你都说进不了192.168了，你能说你设置好了？？
