升级到 22.04 后，以太网不工作，wifi 工作正常？

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：

显示没有有线网络

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：

看来 Killer E2500 的以太网卡已经上市了。问题是
