AX200网卡目前内核已经支持，AP模式仅支持2.4G，另外请问具体是用什么方式或者工具开启的热点呢？

麻烦在开启热点之后，取一份内核日志供研发同事分析一下（可以贴在本帖下）：sudo journalctl -k > kern.log

kern.zip有线连接之后，无线开热点。日志已发

大佬怎么样了

试验成功了吗？理论上应该可行

不行，没网

麻烦取一份完整的日志看看，研发看发现你的环境好像有问题，开热点的时候dnsmasq崩溃了，导致无法联网。

dnsmasq[12156]: segfault at 5608578647ea ip 000056084e045a9a sp 00007ffc11595100 error 4 in dnsmasq[54a9a,56084dff9000+4e000] likely on CPU 11 (core 3, socket 0)

取一下完整的日志：
