What's your network topology, i.e. is your NetBSD machine connected to ADSL
modem? What kind of modem is that? How many DHCP servers do you run on your LAN?
Also can you provide the following information when Internet connection is

When the Internet connection drops, does running '/etc/rc.d/dhclient restart'
bring it back??
