The IT person did this when he changed out the old access points and said that he would be changing it back to the public IP I mentioned in an older post. The IT person hasn't been in for my friend to talk to, so until the IT person is around I'm stuck. I will let you know ASAP!!
I felt dumb when you pointed out the obvious because I had the same issue a while back when TWC changed out my cable modem in my house for the WiFi/Cable Modem (which I no longer have.) Never again will I go with anything TWC related.
