Description
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
- 2.4 GHz: 802.11b/g/n SoC, 1T1R, 27 dBm
- 5 GHz: 802.11a/n/ac MT7610E, 1T1R, 25 dBm
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.

Research direction
Start by reading the linked OpenWrt commit and comparing its wireless power handling with the MT7688AN and MT7610E behavior on the Wavlink WL-WN570HA1. No source file or test is named, so reproduce the reported 24 dBm and 18 dBm limits and trace the driver path responsible. Done means the radios can use the stated 27 dBm and 25 dBm limits without reducing client-observed signal strength.
