我有一台 Thinkpad T14s (AMD)，配有联想直接提供的 WWAN 卡。但调制解调器管理器似乎无法检测到该卡？

但是，当我运行“Modem-Manager GUI”时，屏幕一片空白；
而当我运行“mmcli”时，屏幕显示“未找到调制解调器”。
我对 Linux 有大约 3 年的深入研究，但这是我第一次使用 WWAN 笔记本电脑，所以不知道下一步该怎么做。
我也看到这个帖子至少我不是一个人在苦苦挣扎，尽管我不确定我是否错过了什么最新信息。我还注意到其他类似的帖子都在谈论使用 USB 调制解调器而不是内置卡，不确定是否存在实际差异。
答案1
Fibocom L850-GL / Intel XMM7360 WWAN 卡在我的 Thinkpad 上开箱后无法使用，即使获得联想的任何支持也无济于事。
有报道称，有人使用非官方的abrasive 在 GitHub 上的项目。几年前我的卡就可以用了，但只能手动加载驱动程序，而且对于工作环境来说并不可靠。
