cbl modem->cable router to get wireless and add ports - Help with settings

[jazzisjazz]

Howdy all,

I need to take the signal from a standard cable modem

and pass it to a cable wireless router netgear cg3000D ( For reasons beyond my control I can't just replace the modem with the wireless cable router).

I hope to add a wireless signal and a couple ports by doing this.

my understanding is that since there is no wan access for the cg3000d that I have to

disable dhcp for it

and change its lan address to something that the cable modem can send to

then come out of the cable modem port and go to one of the cg3000d lan ports and I should be able to pass the signal on wirelessly and on the remaining lan ports of the cg3000d

I am not clear on what the lan address of the cg3000d should be set to and if any other settings need to change

I will provide whatever details are needed to help me understand the proper way to set the lan address etc. of the cg3000d.

Any help appreciated.

No. The cg3000 is a router and modem in one. It will not take Ethernet input and route it for you as the WAN is wired to the internal modem so you need coax. Any reason you cannot call your cable provider and have them make it your OWNED modem? Is it not supported by them or is there anther reason you are trying to use a combo device as just a router?

was reading here

and it seemed like it might work

The modem belongs to someone else didn't wan't to remove it just add what I needed from a part I already had cg3000d

If you can't put the CG3000d in place of the existing modem, then your best option is to get an actual wireless router that has a regular ethernet WAN port and connect it to the cable modem.

If your initial device was a combo unit [or modem and separate router even] this would work, you could use it as just a switch. However, since your initial unit is just a modem, you will not be able to get MULTIPLE ip's from it {unless you call up your ISP and they offer you multiple IP's over a single modem} and so only ONE device will work this way, which is clearly not what you want or you'd just use the modem.

I do not know about that situation if the Hughes.net modem was a router the guy could make it work but I suspect theirs works the same way cable modems do and its just a bridge device with no routing. In which case go buy a cheap $40 router at best by and go nuts. YOu want an N router these days though for sure. G caps out around 12Mb/s though and if thats all you need, you can probably get one REAL cheap. I see them at good will from time to time in my town for like $10.

is there no way to clone the mac of your modem to your Modem/router? because that might work...
