OT, but I'm curious, what kind of router do you have? That seems really bad. I tested this on my laptop (over WiFi, in a very heavy traffic apartment building) and see the following:
50 packets transmitted, 50 received, 0% packet loss, time 49115ms
rtt min/avg/max/mdev = 0.751/1.436/5.000/0.812 ms
I don't say that to brag, I really think that's definitely expected for any LAN device. 63 packets transmitted, 63 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 1.659/110.684/1805.961/305.145 msWhat model of router is it? This really feels like a situation where something has to be broken, I can't imagine any router, no matter how cheap, has an expected ping rtt maxing out at around 2 seconds. Notably, your minimum rtt is under 2 ms, so it's definitely capable of getting a response to you faster than that, maybe it's just overloaded or something?
