Is changing transmit power will increase wifi coverage

No, it will actually make it worse cuz noise.

@Lolita_Magnum I tried tweaking it to low & medium but low gives lesser speed than high and 2.4 GHz gives best speed in low TX instead of high.

I mean I get 200 Mbps on 2.4 GHz on low
Whereas on high it gives only 60-80 Mbps.

I think it's due to interference as other routers are closer to it with max TX power.

There are other variables too, and having a decent router that is actually up to the 802.11 spec is also important.
While by default most routers push for those 100mW of radio output, but if your own client device is not capable of about the same then it's just loss and interference for others, Wi-Fi is bidirectional.

I have TP-Link wifi 6 router with both 5 & 2.4 GHz having wifi 6. I get this interference issue on that router. Also both my Motorola devices support Wifi 6.

I think if I switch to wifi 6E then it'll solve the issues.
As my phones support it.
