This is consistent. What worries me is I even loose packets to the 1841 (172.16.0.254) on a traceroute

traceroute 172.16.0.254 traceroute to 172.16.0.254 (172.16.0.254), 64 hops max, 40 byte packets 1 router (192.168.100.253) 0.868 ms 0.814 ms 0.836 ms 2 172.16.0.254 (172.16.0.254) 2.084 ms * 2.239 ms

but not if I traceroute to microsoft? Also flood pings are fine to the 1841.
