4 years ago Hi. I have that device and im experiencing problems in the 5Ghz network with openwrt 19.07.2. Does not work at all. I'm really n00b using openwrt and linux so ill try to explain my self as good as I can.
Once you install openwrt 19.07.2 master, you can turn on the 5 ghz radio, in dafault it uses channel 36 and I can connect to the AP for a short period of time (1-3 min) then it starts failing. If you change channel even after a hardreset lets say to channel 100. The wifi don't even show anymore. You get a log like this:

It was hard for me to find the original firmware but after some months I was able to revert back to original firmware. Although the firmware it self is buggy, the 5 ghz radio is stable, I can change to channel 100 w/o issue and the range is quite decent.
On the other hand I have been using the 2.4ghz network and it works... It was quite stable for more than 2 months. I haven't use it for a long distance, just as client device with 1 wall and maybe 10m on a different floor.

The Wavlink WL-WN570HA1 supports 27dBm and 25dBm on its 2.4Ghz and 5Ghz radios respectively. See the commit page:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=a160f50d4f240019fafe95e80701ebb871c788fe
Since upgrading to OpenWRT the signal strength is materially reduced (the radios cannot be set more than 24dBm and 18dBm respectively). The reduced power relative to the stock firmware is confirmed using wireless clients (material reduction in signal strength).
Several people are having the problem. See e.g. https://forum.openwrt.org/t/is-the-wavlink-wl-wn570ha1-fully-supported/59671
