R7000 can't access admin page anymore and DHCP IP Range changed on its own
I noticed recently that my internal IP range changed from 192.168.1.* to 10.0.1.* on its own. I believe I had the router configured to auto update to new firmware, so I'm guessing it updated itself a...
I was able to determine the cause. It tipped me off when you said the IP range changes when there's a second device doing DHCP. I noticed there were new computers on my network when I looked at network file sharing. I use the Netgear Powerline device to get wired connections to my living room. What I believe happened is that my neighboring apartment unit recently set up internet and is also using a powerline device. I noticed my DNS suffix was changing to a different address which is the ISPs instead of my router. I put 2 and 2 together and realized my network was overlapping with his via the powerline. I never set up an encryption key on the powerline so it was still using default settings and connecting to my neighbors powerline. When I added the encryption key, the problem went away and my network returned to normal. Next time I should follow the instructions when setting up new network hardware. Oops

I believe I had the router configured to auto update to new firmware, so I'm guessing it updated itself and changed its settings. When I try to access the admin page nothing loads. I've tried 10.0.1.1 and 192.168.1.1 and nothing comes up. I'm wondering if anyone else has had this issue recently. I will eventually hard reset to factory settings and set it back up that way, but I'm hoping to exhaust my options before going down that route. Any ideas?
NG routers will switch to a 10.x network when they see the exact same network on the same wire. (elliminates duplicate IP subnet issue) Sounds like you have DHCP running on something else, lilke another router, or your ISP provided router modem combo in the 192,168.1.x subnet.
