英特尔公司：未知
保罗
我认为问题出在我的 WiFi 驱动程序上，因为我无法连接到 5Ghz Wifi，但我可以在 2.4 Ghz 上连接。
我需要使用英特尔® Wireless-AC 9462的驱动程序（尝试安装它们但没有任何改变）
这是我的报告，可以帮助您帮助我：

我尽我所能，但一无所获。我希望这会像这个人的问题一样得到解决：ubuntu 17.04 无法使用 Intel Corporation Device 24fd (rev 78) 扫描任何 wifi

首先，让我们确定您拥有最新的固件：
wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb
sudo dpkg -i linux*.deb
重新启动并向我们展示：
dmesg | grep iwl
I will continue this answer after we gather the results above.
EDIT: Your wireless device clearly sees the 5 gHz access point now. We notice that the encryption method is shown as WPA and WPA2 mixed mode.
Please check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6, 11, 44 or 52, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.
Now are you able to connect to the 5 gHz access point?
