Sometimes my internet connection just dies. I can not ping anything or do
anything. This carries on for half an hour or so, then everything suddenly
works again. What is going on? Is there a bug in the e1000 driver? Can I type
some Solaris commands that show what is going on? The strange thing is that
Windows PC / iPad works fine, I can surf the web without problems. So the
problem is somewhere on the Solaris 11 Express PC. Here is some output when the
Solaris 11 Express PC just hangs:

The next time internet dies, what can I do? Are there any commands I can use to
restore connection? What is the problem? Is there a bug?
