Can't access 192.168.100.1

[HenryLeeChi]

Hello.

I just got a new modem CM1100 and I can't seem to access 192.168.100.1 on my pc. I can access it perfectly fine on my cellphone though. Default gateway seems to point to my router 192.168.1.1 if that is of any relevance. ISP is WOW. I had the SB6190 modem before and was able to access with that modem but had to get a new modem due to lag spikes.

Any ideas on why I cannot access?

What Mfr and model# router do you have connected between the CM modem and PC. 

Can you connect to the modem directly with a PC?

 the router is a netgear R7000P. I can connect directly but I still won't be able to access 192.168.100.1. I have already tried unpluging, disconnecting the coax, connecting directly to my pc, and then plugging back in with the coax disconnected. That doesn't allow me in 192.168.100.1 either.

Press the back reset button for 15 seconds then release.

Just tried that and I still can't log into 192.168.100.1 on my pc

factory reset my modem AND my router and now it seems to work!

I would either make contact with NG support or get you another modem. Seems like the modem maybe in a bad state.
