Here is my config and test results:
All of the recommendations so far are incorrect and/or baseless. This is an Intel bug/defect and they need to fix it in all of their WiFi.

I called Linksys/Cisco, waste of time. They told me to return the router.
I called Lenovo, actually they tried but still they referred me to Intel.
I called Intel let's just say...they aren't happy.
Oh yeah...this IS an Intel issue.
