   Cox does not pay enough to attract and keep people who are smarter and   
   more helpful.   
      
   Anyhow.  Dlink has some pretty bad firmware bugs.  Make sure you upgrade   
   your router if it is running old versions.  I cannot say that the latest   
   version is always the best choice either.  They have been known to   
   introduce bugs in new revisions that didn't exist before.   
      
   I'm sure that the Cox troubleshooting training would include   
   disconnecting routers and firewalls as a troubleshooting step.  The   
   person you talked to just didn't think of trying this.   
      
   Good call on the MTU setting though.  Devices are supposed to figure out   
   the path MTU automatically but it can often fail for unexpected reasons.   
     Perhaps Cox started filtering ICMP traffic on one of their routers   
   causing the MTU calculation to fail.  A provider will sometimes turn off   
   ICMP to avoid certain denial of service attacks.  It would be better if   
   they could disable it only when the load on the router climbs too high.
