公司WiFi总卡成PPT?罪魁祸首可能是它!

公司WiFi总卡成PPT?罪魁祸首可能是它!

一、卡顿真相：你的交换机“超载”了

就像小货车拉不动10吨货，选错交换机分分钟堵死全公司网络！典型翻车现场：✅ 开视频会全员掉线 → 交换机“脑子不够用”（处理能力不足）✅ 传文件比蜗牛慢 → 交换机“力气太小”（带宽不够）✅ 财务部电脑总中毒 → 交换机“没装防盗门”（安全隔离缺失）

二、傻瓜式选购指南：按公司人数对号入座

1. 小微公司（20人以下）

场景：共用WiFi，偶尔打印推荐设备：
华为S1730（客厅级路由升级版）
锐捷RG-S2920（带“交通指挥”功能）避坑：别买超市同款！需要能划分“虚拟办公室”（VLAN）

2. 中小公司（20-200人）

场景：分部门用网，监控连WiFi黄金组合：
主心脏：H3C S5130（支持50个摄像头同时在线）
备选：锐捷RG-S5750（部门间设“隔离墙”更安全）关键指标：看准“万兆上联口”（相当于给网络装高速匝道）

3. 中大公司（200人+）

场景：多楼层联网，异地开云会议顶配选择：
华为CE6857（自动修复故障的“智能心脏”）
H3C S6850（防黑客“金刚罩”加持）老板须知：核心交换机=公司网络地基，省钱的后果是天天修网！

三、真实省钱案例

某工厂改造前：
用家用路由器当核心
抢考勤打卡要靠运气
改造后：
换锐捷RG-S5750+华为CE6857
文件传输速度↑500%
全年网络维修费省了6.8万

四、3个防坑口诀

“容量买大不买小”：像买鞋留余地，交换机容量至少预留50%
“问清扩展性”：确认未来加设备能否直接扩展（避免整体换血）
“售后看响应”：选2小时上门服务的品牌（锐捷/华为金牌服务）
