    Reading what you've posted, it sounds like a simple case of the modem was not rebooted when connecting it to a different Ethernet device.  The modem will only provide a connection to whatever device was connected to the Ethernet port when it last booted up.  If you connect a different PC/router/etc., rebooting your modem should make it work again.

    Edit:

    To add to my above post, if you're DPQ3212 has the battery backup installed (which as old as they are you may have actually gotten a battery backup with it), that'll also need to be pulled during a power cycle otherwise the modem won't actually lose power when the power cord is removed.

    There's a reset button on the back, all they have to do is press and hold it for 10 seconds. (Maybe less, but I like to be certain).

First, unrelated to your problem, I suggest upgrading the Cisco DPQ3212 phone modem to the newer Arris TM3402. This should be a free upgrade you can do at your closest Cox store. Make sure it's that model and not the Panoramic gateway which they will try to upsell you too.

Second, to be clear, are you going DPQ3212 > Time Capsule(router) > Orbi RBR10(AP mode)? If not how do you have the devices configured?

Sounds to me like the problem is you are trying to connect a AP to a modem with no router in between. See instructions here to change RBR10 from AP mode to router mode. The instructions are actually to turn it to AP mode but same concept. After doing that reboot the DPQ3212, wait for it to be up and then reboot the RBR10.
