有没有人ax200 网卡在deepin 15.11上用起来的？
现在系统已升级了kernel 5.4.7，firmware也更新官网的了，但是现在情况是蓝牙可以使用了，但是无线还是没有反应：

看dmesg前面ax200识别出来了，但驱动加载有failed，iwlwifi-cc-a0-49.ucode，iwlwifi-cc-a0-50.ucode是什么？网上没查询到，官网的fireware是iwlwifi-cc-a0-46.ucode已经下载最新版本了。

有高手能帮忙解答下么？
谢谢～

或者大家谁有：
iwlwifi-cc-a0-50.ucode
iwlwifi-cc-a0-49.ucode

两个文件可以共享下的么？试试是不是这2个文件的问题～

谢谢

我也是这个网卡，同样的5.4.7内核，虽然同样会报两个固件加载失败，但还是能用。
我现在是用的ubuntu 20.04，以前用19.10的时候wifi也可以用

据这个 https://bugzilla.kernel.org/show_bug.cgi?id=204821#c5，原因是因为ax200内部PCI实现（至少在某些主板上）不支持X16的PCIE slot。有人在bios里手动设置成X1/X4就没问题了

我也遇到了一样的问题，内核是符合要求的，也将驱动复制到了/lib/firmware 但是还是不行，只能以普通驱动工作，速率很低

联想14s遇到同样的问题， 求大佬指点下，一开始可以用，切换系统后再切回来，wifi就用不了了，bt可以用
