A few questions:

1) How do you connect to the internet?  Cable modem?  What type?  Make 
and model?  USB or Ethernet?

2) What does your network look like?  Internet->Modem->RH9->LAN?

3) Can you provide a traceroute listing that shows the path out of your 
network?

4) Anything of interest on the console (Ctrl-Alt-F1)?  In 
/var/log/messages?  In fact, please skim /var/log/messages for sensitive 
information then post this file somewhere we can look at it.  Rough 
times of outages can help here.

5) What is the output of ifconfig?  Any errors logged there?  Is the TX 
and RX byte counts doing anything during outages?

That should get us started.
