DIR-860L 5GHz Not working

Description

Router seems to be working fine but it won't enable the 5GHz radio. It always says Wireless is disabled or not associated. The 2.4GHz is fine. Any idea how to fix this?

Logfiles please. Openwrt version should also be told

comment:2 Changed 21 months ago by karesch@…

I had similar issues on r49221. Router seems to be working fine, but under heavy load on radio0 (ac) a strange thing happens, you see the following in the log (see below 2 separate examples) and radio0 gets significantly slower, but otherwise the router works normally.

Somewhat, my problem is the same. I can only use channel 36. If I use different channels, my 5G won't initialize
