当它表示已连接但您无法连接到互联网时

这表示计算机已连接到接入点 (AP),但接入点 (AP) 或与接入点 (AP) 连接的外部网络有故障。

当显示没有无线网络适配器消息或没有无线网络 图标时

这表示无线网络设备设置为不使用或设备无法识 别。

检查无线设备是否在设备管理器窗口中正确识 别。 如果设备设置为不使用,请右击并从弹出菜 单中选择使用。

答案2 检查是否已对接入点 (AP) 和计算机输入同一网 络密钥(密钥)。网络密钥是用于对接入点 (AP) 和计算机之间传输的数据进行加密的密钥。建议 手动设置网络密钥。

检查接入点 (AP) 设置

有关接入点 (AP) 设置,请参阅接入点 (AP) 制 造商提供的用户指南。

答案3 检查环境是否适于使用无线网络。无线网络的使 用可能受环境和距离 或门)会影响无线网络的使 用。请在层高足够的开放空间(距墙壁 50cm)中 安装接入点 (AP),还要远离所有其他无线电信号 源。

答案4 检查接入点 (AP) 的运行是否正常。

如果接入点 (AP) 运行不正常则关闭接入点 (AP),等待片刻后再打开接入点 (AP)

验证接入点 (AP) 的固件版本是否为最新版本。 (有关接入点 (AP) 固件的详细信息,请联系接入 点 (AP) 制造商或购买接入点 (AP) 的地点。)

答案5 验证是否已将接入点 (AP) 正确地连接到网络。 通过将有线网络电缆(已连接到接入点 (AP))连接 到计算机验证网络运行是否正常。

答案6 再次检查网络密钥设置(密钥)。如果已选中代码 自动转换(一种密码功能),但即使无线连接正常 也无法进行数据通信,则建议手动输入网络密钥 (密钥)

答案7 请按如下说明检查接入点 (AP) 设置。(以下建议 针对的是标准环境,因此可能会因特定无线网络 环境而异。)

网络中有多个接入点 (AP) 时,请检查每个接入 点 (AP) 的信道设置。各接入点 (AP) 采用相 邻信道时,电磁波间会产生干扰。请将各接入点 (AP) 信道设置得更分散一些。

(例如:Ch1Ch5Ch9Ch13)

如果将接入点 (AP) SSID(服务群 ID)选项 设置为隐藏,则无法在计算机中搜索到该接入点 (AP)。建议取消选中接入点 (AP) 的隐藏选项。 SSID 是用于区分无线网络的名称。

建议采用长前导。前导是一种用于数据传输同步 的信号。某些类型的接入点 (AP) 支持短前导, 但这可能会引起兼容性问题。

建议采用静态 IP

由于静态信道选择较之自动信道选择更为可靠, 因此建议采用静态信道。
