OpenWRT - Weak WiFi Signal

Question

Computer networks

There is an Asus WL-600g router with OpenWRT firmware. I ran into a problem:

On the factory firmware, access to the network even from a neighboring apartment was acceptable, the signal quality according to the readings of any programs was at the level of 98% in the "line of sight" zone, and from 60% through 2 walls. Now, even when the netbook is standing directly next to the router, the quality does not rise above 70%, and the network is practically not “visible” through the wall (-85 - -78dB). What settings can you dig? WiFi channels changed, b / g / n and encryption methods also tried different ones. I achieved 60% in the line of sight (2 meters to the router), but still it's not the same 80% as before.

Answer 1

somewhere, in the advanced wi-fi settings, there is an item responsible for the transmitter power, try changing the value there.

Answer 2

add native firmware. if the situation does not change, then the problem is in the hardware (output stage).
