No 5 GHz radio detected

I have a TP-Link Archer C60 v1 with OpenWrt SNAPSHOTS and the 5GHz radio is not detected. I posted an issue here.

Somebody could help me?

Your report shows a self built image. Does it happen on an official snapshot? What about the official stable release?

The error happens on snapshots. Compiled by me or downloaded from downloads.openwrt.org. In the stable version it works fine.

Has the problem been resolved? If so, please let others know how and close the topic.

The only solution that worked for me was the PR https://github.com/openwrt/openwrt/pull/14611, but the author says it is not correct. I have not been able to follow the alternative solution of using ath10k-bdencoder. There is not enough information to understand what I have to do.
