我遇到了与“帮助查找内置无线网卡的 ID“，只是它是一台笔记本电脑而不是平板电脑。我正在尝试安装 Lubuntu 19.10，但未检测到内部无线设备。lspci 或 lsusb 中没有相关条目。但就我而言，/sys/firmware/efi/efivars 中也没有 nvram 文件。
任何帮助，将不胜感激。
编辑：
笔记本电脑是 Jumper EzBook 2。它预装了 Windows 10，无线适配器被 Windows 识别为“Broadcom 802.11n 无线 SDIO 适配器”，并且工作正常。我已完全删除 Windows 安装，并尝试安装 Linux 发行版。到目前为止，我尝试过的所有方法都无法识别无线适配器。
