现在我需要哪个驱动程序?我必须遵循哪些步骤?

答案1

07:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

以上输出信息lspci表明您有 BCM4312 无线。您需要有线互联网连接来修复它。

打开终端并输入:
sudo apt install b43-fwcutter firmware-b43-installer

这应该可以解决问题。sudo apt update如果是新安装的 Ubuntu,则可能需要先执行此操作。

重新启动计算机。
