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...

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 upstairs router is a D-Link DIR-880L and doesn't appear to have an access point mode (router/bridge).

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

I don't see how it could. With no router (and DHCP server), how
would a device which is wireless-connected to it get an IP address, and
from where? I would not expect your ISP to hand out public IP addresses
like candy. To do anything else, I'd expect a local router to be
involved.> The upstairs router is a D-Link DIR-880L and doesn't appear to have

See, for example:https://community.netgear.com/t5/x/x/m-p/1463500
That's written for a Netgear C6300-as-WAP, but the steps are about the
same for any other router (any make/model) which lacks a one-step WAP
option.> [...] Could I assign a static IP to the router and leave the modem in

"yes":Could I configure the D-Link DIR-880L with some kind of fixed IP
address, and disable its DHCP server, and then connect it to the
C7000v2 in its default modem+router mode?
That's (roughly) the usual ad-hoc WAP scheme.
> C7000v2 Modem subnet: 192.168.0.1xThat's as expected.
> DIR-880L Router subnet: 168.192.100.1xx
That's not impossible, but it would be unlikely. "168.192.100.1xx"
would be a public IP address (Sprint). Assuming a typo,
"192.168.100.*" is typically used to access a DOCSIS (cable) modem (at
"192.168.100.1"), not by a router LAN.
In any case, a configuration with multiple routers, and, hence,
multiple LAN segments/subnets, would typically suffer from problems with
"double NAT" (on all but the outer router), and communication between
devices on the different segments/subnets would require extra effort
(typically static routes).A configuration with one router (and any number of WAPs) uses one LAN
subnet, and avoids such problems.The D-Link subnet is not a typo (see attached). I will seek out other resources. Thanks for your time and energy.
