From: Steven Luo <steven@xxxxxxxxxxxxx> It seems that OFDM weak signal detection should be enabled after an ANI state reset, as indicated by the initial setting of ofdmWeakSigDetectOff and what the open Atheros HAL does. Unfortunately, the reversed sense of ofdmWeakSigDetectOff (true if weak signal detection is NOT enabled) seems to have resulted in a mixup here, causing weak signal detection to be disabled. This patch significantly improves reception and throughput from distant stations for my AR5416-based AP running compat-wireless 2009-06-25.
