Ubuntu 12.04.3 中无法建立无线连接

2024-6-3 • tag-icon

我在 Dell Inspiron 15R 系统上运行 Ubuntu 12.04.3 LTS。它根本找不到无线连接。我尝试从本论坛上讨论的大量类似帖子中寻求帮助(Intel Centrino Advanced-N 7260 没有无线功能)，但没有运气。

内核信息如下：

我也尝试按照以下线程的建议加载固件，但结果却令人失望。

Intel Corporation 7260 版本 63 没有无线

我非常感谢这方面的任何建议！

为了诊断故障，让我们加载驱动程序并查看是否引发错误：

sudo modprobe iwlwifi

如果有任何错误或警告，请发布。接下来，让我们检查消息日志以寻找任何线索：

dmesg | grep iwl

一旦我们知道结果，我们就可以为您提供进一步的建议。
