I got my ISP to put my modem into bridge mode, so it acts as ONLY a modem. I have my own router, which is on 192.168.0.x with DHCP on and some static IP assignments. Everything works fine. But my modem is on a different subnet, and honestly it changes. It WAS 192.168.40.x but I THINK now it’s 192.168.100.x - I have no control over it, it’s my ISP that changes it and I have no idea why.

What I want to do is to be able to access my modem management interface so I can see if it’s connected to the internet (for troubleshooting, when my internet fails - is it my modem? router? etc.) I can’t do that from a PC on the 192.168.0.x subnet obviously. But it’s really annoying to physically connect a PC to the modem and set static IPs GUESSING at what subnet the modem management portal is on.

Any advice? Ideally, I’d love for a way to access the management portal from any PC anytime… I guess the solution there would be to put everything on the same subnet? More difficult than it seems when ISP decides to change it on a whim.

As an aside, I tried setting a static IP on a laptop hard-wired into the modem just now and neither 192.16.100.1 nor 192.168.40.1 were allowing me into the modem’s management portal so now I’m at a loss. That said… this was while my modem was connected to my router still via a different LAN port. Do I have to disconnect all other LAN ports before it will work? Or has the modem’s subnet changed AGAIN?

Thanks for your help.
