I build a firmware from the latest LEDE source, but I can't start wireless and there is no Wireless in luci menu.
I have tried the lastest Development Snapshot builds, has the same issue.
But @hnyman 's build works well.

Yes, recent commit to introduce support for ipq40xx devices broke ath10k wifi for several wifi chips. The reason the removal of 936-ath10k_skip_otp_check.patch by commit https://git.lede-project.org/?p=source.git;a=commit;h=cc189c0b7fa015978b04bb663a75b1da726376b5
It is still unfixed in LEDE master, but I have included a small fix in my own build and thatswhy my own build has wifi even now.
Explanation can be found in discussion in Netgear R7800 exploration (IPQ8065, QCA9984) - #272 by hnyman
Patch available in PR 995: https://github.com/lede-project/source/pull/995
OK, Thank you very much.
