电信5G千兆套餐WiFi6网络优化实战
基础硬件
WiFi6 技术（802.11ax） Wi-Fi 6（原称：802.11ax）即第六代无线网络技术，是目前新一代的无线局域网（Wi-Fi）标准。
Wi-Fi 6 相信大家也不陌生，它就我们此前常说的 802.11ax，自从2019年 Wi-Fi 联盟改名后已经经过了接近2年的发展，它不仅有着更快的速度、更大的频宽以及更多的装置可同时连线，同时是未来物联网的重要一环。目前市面上 Wi-Fi 6 终端设备已经彻底普及，Wi-Fi 6路由器的价格也充分亲民接地气。
Wi-Fi 6路由器高带宽和高并发：单流速率从之前 867Mbps 提升到1201Mbps/s，最大带宽从之前的 6.9Gbps 提升到 9.6Gbps，换算成常用的下载速度就是每秒1.2GB（实际上是每秒20M左右）。而且提升了多设备同时传输时的吞吐量。 低时延和低功耗：WiFi 6平均延时降低是20ms，WiFi 5平均延迟是30ms，时延降低2/3。wifi6支持TWT（目标唤醒时间）机制，让设备联网功耗降低30%左右。WiFi6 是新一代无线局域网传输技术（学名802.11ax），在传输速率、信号覆盖和数据延迟方面相比上一代WiFi5有大幅的提升；尤其是在多终端设备同时连接的情况下，WiFi 6路由器可以显著降低和减少终端设备的延迟和卡顿。
能跑满千兆的路由器规格，目前5G/2.4G双频段AX3000机型即可以满足，打开5G频段160Mhz让更多终端低延迟接入，峰值性能更高，网速更快，充分发挥WiFi 6低延时（20ms）高网速(20－30M/S下载速度)性能，一般近距离能跑到1.6～1.9Gbps左右，隔1道墙递减到900Mbps左右。
在平价 Wi-Fi 6路由器中，这里主要推荐腾达 AX3000型号，它采用 MU-MIMO+ OFDMA 技术，显著提升网络性能与效率、延时更低，满足多人在线游戏、观看超清视频更流畅。2.4GHz 和 5GHz 频段均采用 2 颗外置信号增强模块，同时提升信号增强和接受能力，覆盖范围更广。增强抗邻居家Wi-Fi干扰的能力，有效缓解同频干扰。支持 IPV6 海量 IP ，上网更顺畅。支持 TWT 用时唤醒，低功耗长续航。
基本组网技术
Mesh组网技术（解决无线信号覆盖） 所谓“穿墙”路由器只不过是商家的营销广告而已。由于我国的路由器发射功率是有安全限制的，因信号源与终端接收距离会损耗20～30%加上隔墙又损耗30～40%左右，所以不管多昂贵、多高端、多牛逼的路由器，都会经过两堵墙后信号就很差。如果你家是100平方米以上大户型，必然容易出现信号死角，尤其是复式和别墅、多楼层的格局信号会更差，特别是电梯阻挡必然会让WiFi信号大幅度衰减至零信号。 Mesh组网是目前在解决家庭WiFi信号覆盖上最为流行的方案，它可以让多个路由器之间形成组网成一个网络，这样家里只有一个 wifi网络，让你的设备可以在多个路由器之间无缝切换。 Mesh 组网支持有线+无线混合组网，配置起来也非常方便和灵活，效果非常不错，目前各大路由器厂商的新款路由器几乎都支持自己的 Mesh 技术。 在这里举例用 中国电信光猫路由一体机修改设置桥接模式 光猫配的是四川天邑康和通信的TEWA—708G天翼网关3.0版本或直接升级到TEWA—708G天翼网关4.0版本（2022年12月）最新标配千兆光猫，自己再购买一个无线路由器重新组网。
方案1：最简单快捷的信号扩展方式是使用光猫拨号（默认路由模式），TEWA—708G天翼网关Ver3.0光猫既是调制解调器（Modem）又是主路由器（Router），然后连接自购的无线路由器的LAN口来使用子路由器的WiFi信号。当然，也可以用信号放大器无线扩展WiFi信号，只是信号稍弱或不稳定而已。
方案2：各干各活，干脆把光猫改桥接模式（Bridge），使用自购的高性能稳定路由器拨号，自购路由器作为主路由器来使用安全稳定又强劲WiFi信号。既然光猫不稳定，那就建议关闭光猫的WiFi 功能，设置成桥接模式，让路由器进行拨号，尽可能的降低光猫的负载。 设置桥接模式详情参见电信光猫设置桥接模式
实战体验分享
迎接5G+WiFi6时代的到来，相信大家都不会放过这一波体验大好机会，你到电信大厅办了5G升级及千兆宽带套餐后，本想应该感受光的速度，结果被低性能的WiFi5老路由器或电信光猫路由一体机限制了，依然龟速上网易掉线，丢包高延时根本无法玩网络游戏或体验一下VR三维立体影院。怎么办？今天跟我学一招，手把手轻松教你搞定WiFi6设置，快速破解网络困惑。
我在 2022年11月10日参加“双11”活动抢购了一台腾达Tenda AX3000千兆WiFi6立式路由器（5G双频、家用智能穿墙、一键Mesh组网、EM12单只装）， 2022年11月10日晚上第一时间收到货后就开始正式组网。首先，将中国电信光猫连接电脑后，TEWA—708G天翼网关Ver3.0光猫可用超级密码 s$r5!@Jb 登录光猫后台，将中国电信光猫设置成桥接模式，并关闭网络连接，让光猫单纯完成调制解调器的功能，把接收到的光信号转换成二进制数字信号，不再当路由器用，仅仅提供给路由器数字信号（TEWA—708G天翼网关Ver4.0光猫无WiFi功能，本身就只是调制解调器，并且是个最新标配的千兆光猫，只需要注册登录光猫设置后台就可以使用了。）；然后，用千兆网口连接这台腾达Tenda AX3000千兆WiFi6立式路由器“穿墙宝”作为主路由器宽带拨号上网，放置在客厅电视柜上面，提供IPTV有线信号及WiFi6无线信号，用腾达（Tenda）A12 300M WiFi信号放大器（增强型无线扩展器、中继器、信号增强器）作为路由器穿墙伴侣，放置在阻隔了两道墙的次卧中，测试开启或关闭放大器的网络性能（玩“王者荣耀”、“和平精英”网络游戏时的网速及延时性能测试非常好）。
经过家庭网络改桥接模式组网后，网速大幅提升。修改前光猫宽带拨号上网（2.4GHz）客厅网速130Mbps，已扩展次卧网速91Mbps，IPTV电视下载速度5.4M/S，王者荣耀游戏延时≤130ms；修改后“穿墙宝”宽带拨号上网（5GHz）客厅网速1729Mbps，已扩展次卧网速490Mbps，IPTV电视下载速度20.7M/S，王者荣耀游戏延时≤20ms并且稳定顺滑不卡顿。真正实现了百兆网速变千兆网速，也才真正对得起自己的千兆5G套餐，把套餐性能发挥到极致。
