First, "ifconfig -a" and look at the error counts for each interface.
If you see a lot, then you start looking at hardware (bad cables, dirty
or loose connectors, flakey NICs, etc.).

If the errors look OK, have a look at your (DSL|cable) modem's
statistics and see if there's something odd going on at the WAN side
of things.  If using cable modem or DSL, you may need to reboot your
router and/or modem.  I make a habit of doing that every six months
or so.

If you're running nscd, purge your nscd DNS cache ("nscd -i hosts").
