This is a question for you hardcore network guys out there. ;-) There's a new option in the Wireless tab in DD-WRT v23-SP1 labelled "Sensitivity Range (ACK Timing)". The default setting is 20,000 meters. Can anyone explain what this option actually does, and what it should be set to for a medium-sized house with one wireless router and multiple floors? I'm assuming it has to do with timing of delayed ACKs, but the default value of 20 km is throwing me off.
