我有以下设置：
- 我的 ISP 同时支持 IPv4 和 IPv6 网络
- 我的调制解调器是 Cisco EPC3208
- 我的路由器是 TP-Link Archer C2 (AC750)
- 我的笔记本电脑配有 Intel Wireless-AC 8260，运行 Fedora 25。它连接到 WiFi，但未获取 WAN IPv6 地址。但是，它确实获取了本地 IPv6 地址。当我使用 LAN 电缆将笔记本电脑连接到路由器时，它会创建一个新的网络接口并接收 IPv6 地址，并且可以 ping6 ipv6.google.com。
- 我的手机是 Nexus 5，可以在 WLAN 上 ping6 ipv6.google.com。因此，问题出在我笔记本电脑的设置上。
以下是 WiFi 上笔记本电脑上 ifconfig 的输出：

我尝试了笔记本电脑和路由器的设置（包括重置所有内容），但无济于事。有人知道如何解决这个问题吗？
编辑：我可以确认当我以 Live 用户身份从闪存驱动器启动时也会发生同样的事情。
