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:

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
