5 years ago Also tested version 6.1 and 6.2. Results are the same. Stable but no range.

This seems wrong to me too. Like wrong eeprom reading ? According to TL-WR840NV6.dts these are my partitions:
memory@0 {
device_type = "memory";
reg = <0x0 0x2000000>;
};
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "boot";
reg = <0x0 0x10000>;
read-only;
};
partition@10000 {
compatible = "tplink,firmware";
label = "firmware";
reg = <0x10000 0x3d0000>;
};
factory: partition@3f0000 {
label = "factory";
reg = <0x3f0000 0x10000>;
read-only;
};
};

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.
