TP-LINK 路由器 无线桥接 设置

• 前言

家里Wifi信号不好,想用路由器桥接网络
正好家里有一款TP-LINK路由器,150M,型号为TL-WR742N.

将其当做副路由器(192.168.1.254),桥接主路由器(192.168.1.1)

如果家里没有任何其他联网设备
	那么,只有192.168.1.1 和 192.168.1.254 存在

• 副路由器(桥接路由器设置)

第一步 复位并登录副路由器
1. 长按复位10秒(此举会将路由器之前的设置重置)
2. 插入LAN口
3. ping 192.168.1.1(确认一定是LAN口,网线正常)
4. 浏览器输入 192.168.1.1,admin,admin


第二步 设置副路由器的IP和子网掩码 (以适配主路由器网段)
5. 更改默认IP
	网络参数->LAN口设置->IP地址改为192.168.1.254(具体看主路由器的网段和子网掩码)->保存
	注意: WAN口不连接,WAN口不设置
7. 重新启动

第三步 将副路由器无线连接至主路由器网段
8. ping 192.168.1.254
9. 浏览器输入 192.168.1.254,admin,admin
10. 桥接主路由器
	无线设置->基本设置->开启WDS(此时会提有页面刷新出桥接的SSID)->扫描->输入密码->保存
11. 关闭副路由器的DHCP服务
	DHCP服务器->DHCP服务->不启用
12. 查看运行状态
	运行状态->WAN口状态->WAN口未连接
	运行状态->无线状态->WDS状态:成功

第四步 设置副路由器无线广播SSID和密码

13. 设置副路由器广播ID
	无线设置->基本设置->SSID号
14. 设置副路由器密码
	无线设置->无线安全设置->WPA-PSK/WPA2-PSK->输入密码

第五步 重启路由器

15. 重启路由器
	系统工具->重启路由器

• win10 如何忘记wifi密码
