Ubuntu 18.04 Intel Wifi 9560 无法正常工作

我无法让我的 wifi 卡工作。我尝试了不同的内核版本，并从英特尔网站下载了最新的固件并将其复制到 lib/firmware 中。运行 dmesg | grep iwl 时，我得到以下信息：

[    6.506586] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-9000-pu-b0-jf-b0-38.ucode failed with error -2

非常感激能够得到解决方案。

我也遇到同样的问题，而且有一个 bug kernel BUG at /build/linux-vxxS7y/linux-4.15.0/drivers/net/wireless/intel/iwlwifi/pcie/rx.c:425!
