yes, i've had similar problems with cox both when i had cox at work business 
service, and now that i have cox at home residential service.

this feeds right into the thread that branched off my post about "network 
diameter" in which people are talking about "clue factor".  these networks 
spring up overnight, built by people who are missing some of the 
fundamental knowledge about how all this "stuff" works.  and we're stuck 
with it as end users.
