HTC One M8 Network Name
Ok. I have figured it out. I've learned quite a bit trying to figure this out, I don't have all the details but here is my Hypothesis:

I believe it is a bug in my router. The router performs a search on the IEEE Standards website to look up the manufacturer of each device based on the first three "octets" of the MAC address WIKI. The first three octets (xx:xx:xx) of the MAC address are unique to the manufacturer of the device. For me, my phone is HTC and so the first three octets for HTC are "50:2E:5C". The router must have a bug where it is doing a search and pulling the first manufacturer from the result and using that manufacturer name as the "Client Name". For instance, for my device: Example you'll notice the first hit is "X2E GmbH" which is what my phone is showing up as in my Client List. I don't know why only the android device seems to have the Client Name replaced by this result from the IEEE lookup and not other devices (as all the manufacturers are incorrect, but the client names are correct), but I think it is enough energy spent solving this mystery.
