High Latency and Packet loss

With the n41 metrics it should be working well. The problem is probably in the backhaul with a router in the network path to the internet. If they would and could dedicate a knowledgeable engineer to investigate the behavior in more detail they could probably find the problem. From what I have seen in examining traffic flows from here in the past the external IPv4 addresses rotate in the Atlanta area. I don't have intimate knowledge of the hardware in place so I'm speculating on some aspects of their network architecture. They do use 464XLAT so offer no port forwarding to the end user. Since the mobile aspect/focus is on cellular service the phones do get priority over the fixed cellular gateways. In some places the service is really good but in others not so much. I am pretty sure the controls they leverage for bandwidth distribution are also a big factor as it appears they will compromise on service levels to expand subscription delivery. They may be planning to build out service delivery in a given location to better handle the loads but it seems the cart is before the horse in some places. Just my impression as I have observed a good number of subscribers in urban areas with more population density complaining of the same behavior. They are making an aggressive push to try to be the bigger dog in the fight.
