No, it’s not because of hardware, it’s because of IP restriction or it could be because the data choking happening in the router that you were pinging. It will consider large packets as data packets and drops it. If you try small packets, it never shows you any drop because the device will prioratized the input as voice or video.

As very quick google shows you are exceeding amount of fragments (data) that fits into one packet. In order to support that you would have to change configuration on your machine (and possibly the remote) to utilize it.
