Ok here's what I got: I have one wired router and one wireless router set up in one room. I just built a new desktop that is set up across the house and I do not want a wireless connection. So here's what I did; I bought 50 feet of coax cable, a cable splitter, and an old motorola surfboard modem. I connected the splitter to the tv that's in the room with the new comp and the 50 ft cable. I then connected the tv. The tv works great. Afterwards I connected the 50 ft cable to the modem and then the modem to the computer. Here's where the problem comes in. I have a connection, that's the good news. I'm only getting 10mb/s instead of the 100mb/s I should be getting and the internet still doesn't work. I'm thinking it's the modem b/c it's so old.

So here's the challenge...how do I connect a tv and cable modem at the same time with the materials I have with me (excluding the modem b/c I'm willing to go out and buy a new one)? Thanks!!!
 
I can't help much with the modem. I don't know how "unlocked" ones work, if there is one. See, our old modem quit working once our ISP upgraded something and gave us a new modem...

As for the 10Mbps, modems only run at that speed. So that's all the port is set to. Same with routers. Their WAN ports are almost always 10Mbps. Totally normal.
 
So the new computer is hooked up with a cat5 cable coming from the cable modem. The cable modem is connected to a 50ft coax cable running to the other routers?

Im confused on the part where the begining of the coax cable is connected.

Are you just plugging the coax cable into the splitter of the main cable tv in? An trying to run 2 cable modems for a dual connection to the internet?

If so that doesnt work, as there are 2 mac addresses from the 2 cable modems...

Hows do the router connect to the internet?

The new comp is hooked up with a cat5 cable coming from a modem that is hooked up to a splitter with the tv from my room. The other cable modem is hooked up across the house in another room and connects every other computer together.

Sorry about the confusion. The new 50ft coax cable is hooked up to an old cable modem which is connected to the new comp that is located in my room. Yes I am trying to use 2 cable modems in the same house on the same line. Can I clone the mac address from cable modem 1 to cable modem 2?

The router connects to the cable modem (where the internet originally comes from) in the room across the house.

I'm asking if there is a way to split the cable in my room that goes to my tv to another cable modem to have a wired connection in my room?

So if the modem is getting a signal, why can't I get on the net? It keeps saying server not found. Is there a way to boost the signal?
 
why try to run two modems? Why didn't you run the cat5 from the new PC to the router in the other room?
BTW - The more you split the main cable signal, the more your internet connection speed is degraded.
 
Two modems wont work, thats 2 mac addresses, and you can't give the ISP 2 mac addresses. I guess if you could copy the mac address of the first modem into the second... Or you could try to use a cat5 cable...

I don't want to run the cat5 to the other modem b/c it would go across several rooms, a hallway, and stairs. I don't want anyone to trip over it or see the cable. I understand that the more you split the cable the slower the connection is, but right now it would be better than the 54mb/s it's going right now on the wireless connection.

Ok well I tried cloning the mac address of the router which i did not mean to do. The other computers are fine but when I reset the router, now it says that it can't find the server on the wireless. What should I do?
 
I found this... Seems reasonable. But even if you could change it, I still dont believe 2 modems would receive 2 connections. I know 100% that you cannon do it with dsl and 2 phone ports (tried it recently). However you wire this network in your home, you need 1 modem connected to the cable, and that modem going to your router/switch. If you then want to try to grab a adaptor to plug in a cat5 cable to a port in the router and then convert that cable to a coax and run through the cable line... so be it. I am sure there are ones out there. Does that seem like a viable answer?




A: Your cable modem manufacturer can change it but only to a valid address. Changes are fraught with peril.

The MAC address, short for Media Access Control address is a hardware address that uniquely identifies each node on a network. For example, I have a Gateway computer (a node) that uses an RCA cable modem to connect to a local area network (LAN) run by @home.com, the Internet Service Provider who connects my computer and others on the LAN to the Internet. My cable modem has a unique hardware MAC address: 00-10-94-11-02-21.

Now, suppose I get RCA to change my MAC address to some arbitrary number that appeals to me, say 00-90-84-44-5f-33 and RCA is willing to do it. That's your MAC address, as it happens, so you won't be able to access your LAN any more because your unique number identifying you isn't unique any more. I've stolen it.

That's why Internet conventions (called the IEEE 802 standards) forbid such changes. A modem manufacturer determines a MAC addresses following a careful set of rules that result in unique identifiers.

The procedure for changes is difficult enough that "in practice, it would never be done," says RCA modem technical support. The technician would need to de-solder the chip containing the address and then burn in (i.e., rearrange the transistors on the chip using ultraviolet radiation) a new address. Also "it's slightly shady", says RCA technical support, because, in so doing, you could pretend to be using a cable modem by a different manufacturer than you really are.

You copied the mac address of you rlocal pc to the router. Not even looking at the address of the modem.

And click EDIT, no double or triple posting.
