Once I had one HR200 that didn't connect, after awhile I found the source of the problem was an extra space at the end of the SSID. It doesn't make sense to put an space of the end of the SSID, it becomes invisible unless you try to modify it! And it is not a problem with phones, tablets or PCs because you choose the SSID from a list but with the HR200 you have to type it. I was using Apple Airports on this job.
