I have 2 AP from the same vendor with AR5212 Atheros card set
to WDS bridge mode and works fine with nearly <15dBm between them.
I have another similar developed version of 2 AP with same Atheros AR5212
card but that doesn't work well at 15dBm between them. It works fine with
when there is >30dBm between each other.
Both cases are tested with the same distance, same location and
antenna diversity set to 0.
what could affect the signal strength and performance in the 2nd case?
