1G，依次核对网卡速率、驱动、线材、墙内模块和对端口；若全网突然卡顿，先排查误插形成的网络环路。","faqs":[{"answer":"不能。它只提供局域网 2.5GbE 链路；外网仍受宽带套餐、光猫、路由器 WAN/LAN 口和运营商限制。","question":"2.5G 交换机能让千兆宽带变成 2.5G 吗？"},{"answer":"标准允许在合格 Cat5e 信道上运行 2.5GBASE-T，但墙内模块、接头、长度与施工质量都会影响协商。旧线先实测，不必一上来全部换 Cat6A。","question":"Cat5e 网线一定能跑 2.5G 吗？"},{"answer":"通常不能配置。部分型号只支持 VLAN/QoS 透传，不等于能创建 VLAN；需要隔离、聚合或精细 QoS 时应买可管理交换机。","question":"非网管交换机可以做 VLAN

2.5Gbps，NAS、电脑网卡、路由器上联和线材都要支持；互联网速度仍受宽带套餐与路由器限制。价格为 2026 年 10 月国内电商与跨境渠道参考区间，不同硬件版本需以购买地官方页为准。","items":[{"best_for":"NAS、台式机与 Wi-Fi 6/7
