目前,lspci 给出:
.....
00:14.3 Network controller: Intel Corporation Cannon Lake PCH CNVi WiFi (rev 10)
Corporation HM470 Chipset LPC/eSPI Controller (rev 10)
3c:00.0 Ethernet controller: Qualcomm Atheros Killer E2500 Gigabit Ethernet Controller (rev 10)
.....
正如您所见,以太网和 wifi 都列出了,但只有 wifi 可以使用。如果禁用 wifi,我得到:
我们可以看到,没有列出以太网。并且在升级之前,禁用wifi后,“以太网...”等条目将出现在这个列表中。运行“lshw -c network”后,打印出这些:
