I suggest you to reconfigure your AP in a way it supports single channel operation only (set it to either 20Mhz or 40Mhz, not both) and also if possible, disable auto-channel function of your AP and manually select operating channel\bandwidth, so your wifi adapter won't have to switch between ever changing channels.
