      For roughly the past 2 weeks, I have been seeing our internet connection drop all connections for a minute or so a few times per day. I am currently corralating it with the following error messages in the system log. How can I correct this?

        I have also seen this on dc-based NICs, they seem to just be a really, really, low-quality card. Switching to another brand of card is probably your best bet.
