我的家庭网络在 Linux 电脑方面存在问题，两台 ubuntu 和两台 mint。我查看了日志文件并在互联网上搜索了解决方案。我找不到任何解决方案。其中一台 mint 电脑连接正常，其他三台似乎也有同样的问题。一台 PS3、一台 Mac 和所有 Windows 都连接正常。
我试过了：
- 禁用 IPv6（我认为我的路由器不支持 IPv6）
- 使用 USB WLAN 设备、内部 WLAN 设备和以太网电缆（所有这些都可以在其他网络/窗口上运行）
所以我怀疑这是我的计算机无法用通用语言与路由器通信的问题。但我并不是专家。我希望有人会关心看看我的日志文件，我相信答案就在这里。

好吧，我现在可以回答 50%，因为购买了新路由器后问题已经消失。但我无法解释为什么 x 台计算机不兼容。
