我无法连接到 Wi-Fi 扩展器 (TP-Link WA850RE)。我将其配置为 SSID 与“原始”路由器不同。SSID 不是问题所在。
当我将其 Ipv6 配置为本地链接时，笔记本电脑实际上连接到了扩展器，但没有互联网。当我将 Ipv6 切换为自动时，它无法再连接，并弹出一条通知说Wireless interface (wlp2s0) IP configuration was unavailable。我真的需要一些帮助。
以下是输出ip addr

答案1
我找到了让它工作的方法。我必须在 Ipv4 部分手动配置 DNS 服务器和 DHCP 客户端，并将 Ipv6 设置为Link-local。我在登录到我的 Windows 机器时发现了这些信息，这些信息发送ipconfig到提示符，并通过查看 Wi-Fi 连接的详细信息（也在 Windows 中）。
