Base on the information you provide, I am prettyr sure you are using pure-40MHz. Is there any chance you have the access to the AP and check on it configuration? is it "pure-40MHz above", could you either change it to "20/40 MHz mixed mode", or change it to "pure-40MHz below" and see if the problem is exist?
