The one I looked at first hand was not on a segment of the network that does PPPoE, so that isn't the issue - at least with that one. The other two are doing PPPoE. Strangely, one of them only has problems on one of their devices - a microsoft surface tablet. Everything else supposedly works correctly. I'll look again at the MTU settings on their specific routers. I have not seen anything as far as packet loss goes, I didn't try with larger packets though.
