Starnge problem and ping results

I've noticed problems with my bb connection. I can get online no probs but
when I play any online game it really stutters and ends with me being kicked
from the server, even though my ping is very low. I've raised this with my
ISP and have done several tests and the results are very strange - look
below:

Ping statistics for 195.149.33.68:

Packets: Sent = 50, Received = 50, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 14ms, Maximum = -14ms, Average = 8ms



Tracing route to www-v.nildram.net [195.149.33.68]

over a maximum of 30 hops:



1 31 ms 31 ms 31 ms my.router [192.168.1.1]

2 17 ms 17 ms 17 ms lo1-lon3-adsl20.nildram.net [195.112.5.29]

3 17 ms 17 ms 17 ms lon3-14.nildram.net [84.12.224.29]

4 4294967282 ms 17 ms 16 ms lon1-13.nildram.net [84.12.224.18]

5 4294967284 ms 18 ms 17 ms www1-v.nildram.net [195.149.33.68]



Trace complete.



I've never seen minus numbers in ping rate or such a high number. I'm using
a router (Draytek Vigor 2600G) and all was well until a few days ago. Any
suggestions would be appreciated.

Very odd. You obviously can't have negative ping times! Chances are that
it's a larger *positive* time than the software can handle, and is displayed
as negative due to its twos-complement value.

It's still odd though - because I would expect it to time out rather than
report a very large (or negative) value. Have you set a timeout value with
the -w parameter, rather than using the default? When it reports these large
values, how long does it *actually* take to respond - assuming that you're
watching it?

It could be your MTU settings giving the problem or it could be slow
