Please be aware that if you have a connection drop issue (as in the other thread) is completely different from what is being discussed here. We are working to get a fix for that connection drop issue; however, the adapter must connect at 802.11n, so it may be necessary to force both the adapter and router to 40 MHz channel width.
There is also the possibility of a hardware/integration issue and in such case you may want to contact the system manufacturer.
