Intel AX201 被检测为 AC9462。WIFI 连接问题

全新安装 ubuntu 20.04 后，我发现 wifi 速度比平时慢。我的笔记本电脑是 Acer A515-54g，配备 WI​​FI 6 Intel AX201 卡，但系统将其报告为 AC9462，似乎使用了错误的固件。

以下是该命令的输出dmesg | grep iwlwifi：

清楚地检测到英特尔（R）Wi-Fi 6 AX201 160MHz 卡。

命令lshw -C network则不然

并指出有一个 Wireless-AC 9462 卡。

系统加载iwlwifi-QuZ-a0-hr-b0-*.ucode固件，而英特尔网站列出了iwlwifi-Qu-c0-hr-b0-*.ucode正确的固件。此外，我在附加驱动程序应用程序上看到了以下内容：

布拉

Ubuntu 说我的 wifi 设备不工作，第二个选项“继续使用手动安装的驱动程序”不起作用。

我如何加载正确的固件？

答案1

其实不是，正确的固件已加载。查阅 drivers/net/wireless/intel/iwlwifi/cfg/22000.c，IWL_QUZ_A_HR_B_FW_PRE 宏。你会看到，iwlwifi-Qu-b0-jf-b0- 和 iwlwifi-Qu-c0-jf-b0- 确实用于 Intel Wireless-AC 9462。

我的 MEDION® AKOYA® P17605、Intel® Core™ i7-10510U、Windows 10 Home、43.9 cm (17.3") FHD 显示屏、MX250、512 GB PCIe SSD、1.5 TB HDD、16 GB RAM、笔记本电脑在 Ubuntu 20.04 LTS 上使用最新的 5.6.15 内核时也遇到了同样的问题。仍在努力寻找合适的解决方案。

2020 年 9 月更新：使用内核 5.8，问题仍然存在。我开始考虑将我的笔记本电脑送回去维修……
