CM1100 Modem installation quwpestions
Just purchased the CM1100 modem (along with AX4300 router) and am trying to install the modem. My internet provider's modem/router combo is via fiber optic (FIOS) and there is no coax cable attached to it---just the fiber optic cable. The CM1100's set up instructions state to "use a coax cable to connect the cable port on the cable modem to a cable wall outlet.
Do I need to get a coax cable or just use the fiber optic cable that was attached to the internet provider's modem/router combo?
I tried using the existing fiber optic connection but the Online LED never came up solid green.
What am I doing wrong?

Trying to use a cable-TV modem with some other type of Internet
service?Not describing your equipment, or how it's connected or configured?
Apologies for not being tech savvy.
I hope this additional information helps.My internet provider is Windstream/Kinetic and they provided the currently used ActionTec T3200A modem/router combo unit. I am replacing this single unit with Netgear's CM1100 modem and RAX45 router.
The T3200 is currently connected to the wall via an Ethernet cable to the T3200's WAN port.

you have an Ethernet connection to the T3200A, then you have no use for
a cable-TV modem like the CM1100.> [...] I am replacing this single unit with Netgear's CM1100 modem and

I'd guess that the RAX45 could be used, with its WAN/Internet
Ethernet port connected the way the T3200A WAN Ethernet port is
connected ("to the wall via an Ethernet cable"), but there may be some
configuration details whuch the RAX45 set-up wizard can't puzzle out on
its own. Your ISP should be able to suggest some specific settings to
use on a third-party router with their service.
FIOS ISPs use different hardware from what the CM modem needs. You'll need to contact your ISP to have them help with there equipment. The CM series modem works only on Cable ISP systems. Does not work on FIOS ISP systems.
You should be able to connect your AX4300 router to there modem/router system.
Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem.
3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.Good Luck.
