Ideally, packet loss is always 0%, but that is especially so if it's actually a local router.

You have to be aware, however, that just because a router has a 10.x.x.x address doesn't mean that the connection between you and it is 100% reliable. In many case, a cable modem connection will report a local address that's actually on the far side of the cable line from you. In that case, the connection between you and that *router* is a cable line, a cable modem, and a whole bunch of electronics that routes IP over a cable line.

The fact that you're getting some packet loss here means that it might be worth looking in to - which might mean determining how that router is connected to you - what the network topology is and who controls it.

3-4 packets per hour doesn't necessary mean there's a problem lurking, but packet loss doesn't usually mean *good* things.
