网卡型号

sudo lspci | grep Net
00:14.3 Network controller: Intel Corporation Wireless-AC 9462

已经试过到Intel网站下载驱动丢到/lib/firmware里面,重启没见效。

firmware已经更新到2022年的了,估计问题也不在这。

无线网卡显示unclaimed应该是驱动问题,还在ubuntu20.04下折腾了很多时间,更新backports可以看到无线网卡被驱动了,但同时导致频繁死机,不到10秒死一次,没法用。

网上查了查NUC10i7的机器可能配的是AX 201的网卡,但测出来这9462型号搞不懂为什么。

无线主要是用来带hotspot的,可以带出去用,居然搞不定这无线网卡驱动。

折腾了一天,主要就是尝试换硬件,看看有没有运气。

好在结果不错,主要的改变,bios里面关闭蓝牙,把turbo, hyper threading全部关了,内存从64G减少为32G, SSD拔下来了再从新接上去,主要是因为WIFI的线从SSD下面走,我把线卡在一边。

现在无线网卡正常了,事实显示AX201显卡就是会被显示为9462.

后面再尝试把CPU的性能调回来。
