[RT-N66U] Long ping between clients

[bdruth]

I'm seeing some very strange latency/packet loss *between* clients on the 5GHz wireless network, but not to the N66U and out to the 'Net. Example:

(to another client)
--- 172.16.1.155 ping statistics ---
395 packets transmitted, 371 packets received, 6.1% packet loss
round-trip min/avg/max/stddev = 1.638/187.009/890.861/165.420 ms

(to the N66U)
--- 172.16.1.1 ping statistics ---
21 packets transmitted, 21 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 1.077/1.534/2.215/0.365 ms

I've discovered this because intermittently, when the kids are playing Minecraft with each other, one can't join the other's shared LAN world. Their computer desks are basically right next to each other and they are both on 5GHz, both reporting a 450Mbps TX rate.

I've taken samplings at various times and get consistently poor results, so it doesn't seem like its caused by any particular spike in activity. The N66U has 25 clients, 20 wireless, split relatively evenly between 5GHz and 2.4GHz, with the majority on 2.4GHz being the non-N clients, I think.

Any thoughts before I just start randomly trial & erroring?

As much as I know. Minecraft uses Hamachi, some sort of vpn connection program. And your case, it seems those 2 pcs pinging through Hamachi server on the internet, not locally.
