And indeed it must be a buggy router:
(all pings were collected in parallel)
--- heise.de ping statistics ---
128 packets transmitted, 110 received, 14% packet loss, time 127232ms
rtt min/avg/max/mdev = 21.684/23.611/49.691/3.211 ms
--- 192.168.1.1 (local router) ping statistics ---
126 packets transmitted, 126 received, 0% packet loss, time 125004ms
rtt min/avg/max/mdev = 0.095/0.222/0.336/0.060 ms
--- localhost ping statistics ---
127 packets transmitted, 127 received, 0% packet loss, time 126001ms
rtt min/avg/max/mdev = 0.009/0.029/0.065/0.011 ms
Sorry for the noise!
