Using c6300 in modem only mode
I recently turned off the router on my C6300 to use it in conjunction with an eero system. I had a problem with double NAT because the C6300 was one network and the eero was another. I also had probl...

Did you try "192.168.100.1" in your web browser?

I thought that you could get away without fiddling with your
computer's IP configuration, but, if it doesn't work the easy way, then
I'd try the hard way. (Or just do the reset.)

Yup.

"Compete" or "supplement"? It's not obvious to me that having more
wireless access points would be a bad thing.

"192.168.100.1"?

That's the idea.

One router (doing NAT, DHCP, port-forwarding, ...), multiple wireless
access points -- One big (extended) LAN. Sounds glorious, doesn't it?

Depending on exactly what "lost all network connections" means to
you, it probably is normal. In modem-only mode, a C6300 stops acting as
a router, so (in almost all cases) you get only the single IP address
supplied by your ISP connection, which can't be shared among multiple
devices.

More router functions. However, even in modem-only mode,
"192.168.100.1" should work on a DOCSIS-compatible gizmo (I gather).
An alternative is to do a settings reset, which should restore
modem+router mode (at the cost of losing all your settings).

Because the modem and router in the C6300 are permanently attached,
the only obvious way to use its router with more wireless access points
would be to keep the router in the C6300 active, and disable the router
functions in the other devices. This may or may not be practical for
eero devices (about which I know approximately nothing). But a quick
Web search for:
eero as access point
found:
https://support.eero.com/hc/en-us/articles/207621056
"How do I set up my eero if I want to keep my existing router?"
The "bridge mode" option might be useful.
I contacted eero before I tried bridging. I went into the eero app and set the eero system for bridge. That actually seemed to work. But the eero techalso told me that I should turn off the wireless to avoid double NAT. I think that I confused the router function with the wireless function. As I have researched this, it seems there are settings to enable/disable each of the radios which I now figure is not the same as disabling the router. Of course, I just thought I could go back to the same dialogue screen and turn it back on if something went awry. But, now it doesn't seem you can. Short of doing a reset, do you have any other suggestions for getting back to the router setup besides 192.168.0.1? I included a screen shot of the network settings om my Mac, if that gives any help.
