How do I change the router (G1100) IP address?

[icyulkn]

I have two routers with the same IP address. I need to change the FIOS router IP (g1100) to something else. It's currently 192.168.1.1. Someone mentioned I should go to the Home/Office section and change it there, but when I do it says:
"IP Addresses: The Device's IP address should not be in the range of the IP pool"
when I try to change it to 192.168.1.2. I think it has something to do with the "Start IP Address:" and "End IP Address", but I don't know what to put in here. Can someone tell me exactly what to put in there if I try to change it to 192.168.1.2? I want to make sure I can log into the routers new IP without a problem, or without resetting it. Am I on the right track?

What's the other router, and what are you trying to do?

Uhh, thank you helpful-bot, but ... the G1100 (Verizon FIOS version), does not have a NULL password.

OP, look on the sticker on the side of the router, for the admin password for your router.

Ok, are we all reading the same OP? It sounds like he has two devices that default to 192.168.1.x for the internal subnet.

The OP is saying he logs into the g1100 and tries to change it to 192.168.1.2, but the g1100 says no because it's in the DHCP pool.

My question to the OP is why mess with the primary router? What's the other devices?

You can always adjust the g1100 DHCP to fit your needs. But I would leave it as .1, and make the other device .2

For my own confg at home, my DHCP pool is .200-.254, and my network devices are statically assigned addresses starting at .1

.1 - router
.2 - wap
.3 - client bridge

Etc...

I have two routers with the same IP address.

Two routers means two DHCP servers by default. That would be one too many for one subnet.

If the g1100 has DHCP server on and should have, then the other device should not.
If the other device configuration is changed anyway to disable its DHCP, why not change it's IP too?
The g1100's DHCP's range should shrink to avoid overlap with static address of the other device.


Scenario B:
OP might have a chain of routers. The g1100 DHCP hands out address from its pool to the other router's WAN-port and then that router sees two distinct subnet's, both with 192.168.1/24. That, of course, is a serious error. (Double NAT of a chain ain't nice either.)
The problem description does not exactly support B to be the case, but does not exclude it either.

Thanks for the replies. I found out I could just plug the router into the computer and I would be able to log in there. I inserted 192.168.1.1 and it took me to the admin page. I didn't know I could do that.
