C7000v2 bridge mode and native wifi

Hello. Just got my c7000v2 and have easily connected with Comcast. Piece of cake.

My question is pretty simple, I think. With my last modem (Comcast Arris rental), in bridge mode, I still had wifi through the modem (downstairs) as well as wifi through my D-Link router (upstairs), with 4 different SSIDs - 2 for each device.

If I swich to Bridge Mode on the C7000v2, will I still have wifi networks originating from the C7000v2?

I don't want to try it until this is confiormed. Thanks in advance!

Follow this for your DIR-880L router to configure it for AP mode:

If you want to use the DIR router in router mode with the modem in router mode and avoid a double NAT issue, you can input the IP address the DIR router gets from the modem and put this into the modems DMZ. I use this all the time for having two routers on the same line.

The Arris modem did still have WiFi in bridge mode. It also still had the universal xfinity public access WiFi channel.

The upstairs router is a D-Link DIR-880L and doesn't appear to have an access point mode (router/bridge).
C7000v2 Modem subnet: 192.168.0.1x
DIR-880L Router subnet: 168.192.100.1xx

I have had it set up with both in router mode since Sunday morning and so far, nothing seems to be amiss, though I read there can be conflicts because of NAT being enabled on the C7000v2 Modem.

The only things recorded in the event log on the C700v2 are 2.4GHz WiFi channel changes.

When using bridge mode, wifi and all router functions are disabled.

  And there's no way to get around this if I don't want to create conflicts, but keep all four wifi networks? Could I assign a static IP to the router and leave the modem in router mode, for instance?

       Sounds unlikely. "Bridge mode" and "WiFi" generally are mutually
    exclusive.

       If you want the C7000v2 to act as a modem+router, which would allow
    its wireless stuff to work, then the usual way to add a device like your
    (unspecified) "my D-Link router" to it would be to configure your
    (unspecified) "my D-Link router" as a wireless access point, not as a
    full-function router.
    
       Perhaps that's how it's configured now. Do devices which are
    connected to your C7000v2 get IP addresses in the same subnet
    ("192.168.0.*", I'd guess) as devices which are connected to your
    (unspecified) "my D-Link router"?
