连上无线路由器，笔记本上不了网。

问题描述：

我用的是TP-LINK的无线路由连接的一台台式和笔记本，笔记本上有无线网卡也是这牌子的。连上之后先是显受限制，后来我改了一下IP地址，网卡不受限制显以连接，可信号标志上显示WEP错误。上不去网，怎么调下能上去网。好心人帮帮忙。

问题解答：

找到电脑MAC地址，在无线路由器上，无线参数-MAC地址过滤，添加新条目，放入MAC地址行了

请按路由器说明书设置相关参数。

使用WEP密钥验证SSID方式时,在笔记本和台式机的网卡验证WEP密钥的方式同时选共享,不能用开放方式.
Authentication Type:
Auto: Auto is the default authentication algorithm.It will change its authentication type automatically to fulfill client’s requirement.
Open System: Open System authentication is not required to be successful while a client may decline to authenticate with any particular other client.
Shared Key: Shared Key is only available if the WEP option is implemented. Shared Key authentication supports authentication of clients as either a member of those who know a shared secret key or a member of those who do not. IEEE 802.11 Shared Key authentication accomplishes this without the need to transmit the secret key in clear. Shared Key requires the use of the WEP privacy mechanism.
