Description
It seems like txpower is totally incorrect on mediatek 7628 models.
I see -55dB when my laptop is 30 cm away from the router.
Same test with openwrt Tp-link 740 version 4 signal strenght in luci is -27dB. Version 740 power is limited to 18dB (63 mw) so seems like Mediatek (-55dB) are something like 14dB (30mw) which is wrong. Also any changes like country or txpower does not change signal strength in Luci (still -55dB). Testing mediatek 7628 in 5 meters away make signal -80dB.
May be your driver does not set power at all or at least does not respect country regulatory ?
I am using latest OpenWrt SNAPSHOT, r9945-bc85640cdc.
Driver is stable and working good at 1 meter away but next room is not so good.

Research direction
The report names the MediaTek MT7628 driver and OpenWrt SNAPSHOT r9945-bc85640cdc, but no source file, test, or entry point. Start by reproducing the txpower and LuCI signal readings at the reported distances, then trace how country and txpower settings reach the driver. Done means reported signal strength and power changes behave consistently with the configured regulatory limit.
