odd ppp performance
Greetings,
I have been bothered for years with this problem and I still have no idea
on where to look for the cause.
About once a fortnight I get very slow ppp performance and when I check
with ping I see the packets coming back in groups of ~8. Sometimes it
fixes itself but usually I have to hangup and redial. Here is an example.
mentor:# ping t99
PING t99 t99.xxx.wa.edu.au (192.168.1.99): 56 data bytes

Can anyone throw any light on this weird behaviour, please?
