Why do upload speeds drop much more considerably over distance compared to download

Installing and Using OpenWrt Network and Wireless Configuration

I am experiencing an unusual Wi-Fi issue with the MT7621 chips in my Archer AX23 router. While situated beside the router, I achieve download/upload speeds of 300/350 Mbps. However, in a room just one room away, the speeds drop significantly to 250/100 Mbps. I am puzzled by this considerable speed discrepancy between the upload and download. Is this a common occurrence? If not, could you please explain the factors contributing to this issue?

P.S I am not worrying about the download speed being 250 but the upload being severely reduced at a much bigger factor than download.

A typical endpoint device such as a phone or laptop does not have as powerful a radio transmitter as a router does. So it is usual for the uplink to be weaker over distance than the downlink.

That makes sense.

The only way to resolve this is via fixing the clients, is that correct?

EDIT - Get better wifi cards if able.

Or attempting to reorient the router (or its antennae) to try for better connectivity.

Could you tell me what decides the channel width of a client?

I have a AX201 which supports upto 160MHz and the AP configured to 80MHz yet the device connects with 40MHz on the first row

The client does.

Seems to me something is up with windows.

The same clients on Linux have a speed of 250/200 to 290/250
