CM2200 on 192.168.100.1
I just bought a CM1100 and am extremely annoyed to find that its IP address is fixed at 192.168.100.1. The network I am installing it on uses the 192.168.2.xxx subnet, which means that the cable mod...
"192.168.100.1 is a fixed address for a reason and can not be changed. Its the address of the modems web page for user access."
In all hardware I have set up except this box, my experience is that the port 80 access address is easy to change. For example, I have set my DSL box (that I am now changing out) to use 192.168.2.251. I just set the LinkSys WAP/router that is replacing it to also use 192.168.2.251, replacing the 192.168.1.1 default. My two NAS boxes use 192.168.2.223 and 224, hard addresses that I have set. IIRC they defaulted to DHCP.
Again, for ALL cable modems, (DOCSIS) the 192.168.100.1 is a hard coded default IP address of the modem web management page only. This is not user configurable nor changeable. Do not confuse cable modems with DSL or other non cable modems. You can access the cable modems web page directly or thru a connected router as well using this IP address. The modem is just a modem thus passing thru any and all WAN side traffic from the ISP to a connected wired PC or a DHCP router of your choice where you can set any IP address configuration you want on this router there. Conigure your router of your choice for what you need and desire AT the router, theres nothing to configure on the CM modem.
Good Luck.
