I agree... sounds like an arp issue. You don't happen to have two client bridges before this ap do you? If so you probably have customers battling each other in the arpnat tables. For instance one client starts pinging, other client stops working. Other client starts pinging, first stops working.

An RTS/CTS setting of 3000 means it's effectively disabled. You'd have to set it below 1500 for it to do anything. It's not looking like that's your problem anyway. RTS/CTS will help performance when customers upload large frames (specifically ones larger than your RTS/CTS setting). You'd have

You have to set it to 512 for DNS. Remember that DNS is UDP so if the packets go away because the wireless medium you are using is lossy then there are no more re-transmits. Setting the RTS/CTS to just at the size of a UDP DNS packet creates a virtual TCP-like network for those sized packets.
