Well, one would think so, at least approximately. Some variation
might be expected due to ARP cache entries and how often the cache
is refreshed, but it shouldn't vary widely. Does the length of
time between connection and the first occurrence of the problem
vary widely? What's the shortest and longest "good connection"
time? It could also be that different servers at the ISP are
set for different times and it depends on which server you get
when you dial in.
