You have one IPv4 and one IPv6 address, which is why you see e1000g
twice.

That won't fix it... whatever it is.  You're losing the net and you
need to solve that problem first.  I'd check /var/adm/messages file
and see if there is anything unusual, then fmdump -eV, looking for
clues.

By default, arp will try to resolve (reverse lookup) the IP addresses.
This is a bad thing, if you are not connected to the net, since it will
wait patiently for the reverse lookups to timeout.  When troubleshooting
nets, you should use the -n flag which disables reverse lookups: arp -an,
netstat -rn, etc.
