Just got a new Thinkpad from work, to upgrade the old Thinkpad. When I
take it into my home network, it seems to lose its dynamic arp table
entries after a certain amount of time (haven't pinned down exactly how
long). I noticed that the old Thinkpad also did this. Don't know if this
is endemic of Thinkpads, but my personal Toshiba Satellite never does
that. When the arp entry disappears, I can't ping the other laptop, nor
do any other types of connections to it, like Remote Desktop. However,
once I ping from the Toshiba, the Thinkpads see it again.

Well, I was able to create a static arp table entry on the Thinkpad. But
I'm wondering why one machine works just fine with dynamic arp table
entries, while the other one can't?

Both the Toshiba and Thinkpad have identical routing table entries for
the local network. See below.
