I have Verizon FIOS and I'd like to have a router on each side of the apartment attached to the coaxial cable so that I can have a solid signal throughout. I have the routers configured so that one is primary and handling DHCP and the other is a bridge. Both routers have the same wireless network configuration aside from the channel.
The issue I'm having is that the secondary router is not getting a signal from the coaxial cable. I'm told it's because the WAN is only recognizing the ip of my primary router.
So how do I go about spoofing the ip of my secondary router to make it look like my primary router so I can get it to pick up the internet signal from the coaxial cable?
Edit: My router setup is as follows:
Primary Router
Channel: 11
Static IP: 192.168.1.1
DHCP: on
Available IP Range for DHCP: 192.168.1.4 - ...
Secondary Router
Same network name and password as primary
Channel: 6
Static IP: 192.168.1.3
DHCP: off
The idea being the secondary router would be an extension of the original. I would like to do this via the coaxial cable so that I don't have to run an ethernet cable through my apartment.
1I... don't...yeah... What the heck are you doing! just run a Ethernet cable and put the router in access point mode. There is no way to "spoof the IP" how is comcasts next hop down stream going to know which router to send the data to if both are trying to use the same IP? You need a connection between the two routers and by using coax you are using comcasts smartjack at where ever your dmarc is. Your lucky they have intelligent equipment because if this was a simpler setup you would create a network loop. – Supercereal – 2011-11-16T22:06:34.563
The simplest way to bridge the network would be to connect
Router B
toRouter Main
via Ethernet cable. Spoofing the IP address would be the wrong way to go about it, in my opinion. – iglvzx – 2011-11-16T22:07:07.507Also Comcast also does NATing and it probably does that via MAC address so your neighbor can't just buy a router and a splitter and use your service. – Supercereal – 2011-11-16T22:14:03.623
I was trying to avoid running an ethernet cable across my apartment. I called verizon tech support trying to get the second router added to my account so I can have them both receiving signal from the coaxial. They told me they can't do that and I needed to look in to spoofing the ip address. I assumed they were talking about the secondary router. I'm admittedly not much of a networking expert. – smokingoyster – 2011-11-16T22:24:27.610
There is something missing in the setup description. Which of the routers is the default gateway for the internal network - or are you running two networks? If one router is bridged to the other, how are you doing this without running ethernet? – Paul – 2011-11-16T22:53:11.983
I updated the description. The primary router is the default gateway. Currently the routers are not bridged. That's what I'm trying to accomplish, but I'm trying to accomplish it via the verizon coaxial cable since I have that in both rooms containing a router. I'd rather not run an ethernet cable through my whole apartment. – smokingoyster – 2011-11-17T15:56:38.560
You're trying to bridge your LAN through the same cable that provides you Internet? Isn't that an obviously bad idea? If you want to run two distinct networks over the same physical medium, you need some protocol that separates them and I don't think you have one in this case. – David Schwartz – 2013-02-21T15:27:12.773
