Nothing in the beacon you sent off-list stands out. I don't see a reason why things wouldn't work as they should. The AP is set to country 'US' -- if this is incorrect then try setting the contry code to the actual country the AP is located in. The AP uses an 80MHz channel config in the first channel segment (with center channel 42), which should work anywhere in the world. So there is no reason to believe that the country code would cause issues. However, Intel firmware uses black-box regulatory heuristics which the driver has little control over. With some luck a wrong country code is the reason for your trouble. Otherwise, I don't know. You could try turning configurable features of the AP off one-by-one to see if a factor which triggers the issue can be identified that way.
