IP range mixup
Hi, Recently switched my modem. Got a ATT modem+router. Did a passthrough and configured the network. When I hooked up, router picked 10.0.0.1 as the IP range, probably due to a conflict before I...
Thanks for the help. I was able to resolve by configuring a different IP range for the modem. It seems the ATT modem does not function just as a modem.
Did you unplug these devices and then plug them in again?
What firmware is on the router?
If your modem is in bridge mode, the router should use its default 192.168.1.1 address

To add to what microchip8 says, the fact that your router opted for 10.0.0.1 is an indicator that it probably saw another router when you set up the R7800.
Netgear's setup process tries to be intelligent and looks for anything squatting on 192.168.1.1. If it find something, it tries to avoid conflicts, as you surmised, and latches on to 10.0.0.1.
You can avoid this by putting whatever sits in front of the R7800 into modem-only (bridge) mode.
And when messing around with things do remember to start things in the specified order.
As this is a router, there is probably a modem sitting in front of it. You need to get the devices to forget any inherited settings. Among other things, that means rebooting the network.
Power cuts usually take out both the modem and the router on a network. When the power comes back on, they may start up in the wrong order, with the router starting before the modem is ready. That means that they get confused about which is in charge.
It may help to reboot the whole network in the right order.
Be sure to restart your network in this sequence:
- Turn off and unplug modem.
- Turn off router and computers.
- Plug in and turn on modem. Wait 2 minutes for it to connect.
- Turn on the router and wait 2 minutes for it to connect.
- Turn on computers and rest of network.
