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,但可以连接到 2.4 Ghz Wifi。

我需要使用的驱动程序英特尔® Wireless-AC 9462(尝试安装它们但没有任何变化)

此外,我只能在软件和更新中看到此信息

以下是我的报告,希望对您有所帮助:

答案1

首先,让我们确保您拥有最新的固件:

wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb
sudo dpkg -i linux*.deb

重新启动并显示:

dmesg | grep iwl

在我们收集上述结果后,我将继续回答这个问题。

编辑:您的无线设备现在清楚地看到了 5 gHz 接入点。我们注意到加密方法显示为 WPA 和 WPA2 混合模式。

请检查路由器中的设置。首选 WPA2-AES;而不是任何 WPA 和 WPA2 混合模式,当然也不是 TKIP。其次,如果您的路由器支持 N 速度,那么使用 2.4 GHz 频段的 20 MHz 信道宽度(而不是自动 20/40 MHz)可能会获得更好的连接性,尽管它可能会影响 N 速度。使用固定信道(1、6、11、44 或 52)比自动信道选择更幸运。此外,请确保路由器未设置为仅使用 N 速度;首选自动 B、G 和 N。进行这些更改后,重新启动路由器。

现在您可以连接到 5 gHz 接入点吗?
