Sorry to ask, but could you give a little detail on its history? If I buy it, I will mainly use it as a portable PC, mostly for messaging, and not so much for gaming, so I want one that does not have any issues with the wifi. If I was planning to use it mostly for gaming, I would be less concerned about it since a USB wifi would be fine, but I would be carrying it around in a pocket running a lot of the time, and that would not be a good scenario to have something hanging out of the USB port.
