this is specturm's modem (Technicolor ET2251) and they manage it.  my office is in a building with other businesses so the closet probably has multiple modems in there, but its a simple modem with coax and ethernet port so nothing else should be connected to the modem itself.  I'm not sure how they manage the network.

I'm more curious if its a shared connection. As it in goes modem--->router---->your office. 

So if they have something else connected to the modem

    I'm not sure.  I don't think my setup is anything unusual.  I'm relatively new to the building but I can't imagine other offices living with this problem.  In fact, I would assume other offices may have only wireless connections to their router/modem setup.  I just don't know why everything works fine if I have just one device connected to LAN.  If its not an easy config setting or something, I may just try a different router.
