The 2.4Ghz network works without issues.
But the 5Ghz is very unreliable. Sometimes works, sometimes doesn't.
However, even when it doesn't work, via LUCI, I can scan and discover all the broadcast 5Ghz networks around me. However, I can not connect to any. Not can I serve my own network at 5Ghz.
System information is:
Model: Wavlink WL-WN575A3|
Architecture: MediaTek MT7628AN ver:1 eco:2|
Firmware Version: OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)|
Kernel Version: 4.14.63|
When I restart the 5Ghz radio the system log file gives me this:
