Cable Modem/Router Set-Up Help Needed!!

[dudleydocker]

I am trying to get a friend of mine up and running on his new Comcast cable internet access. He has a Motorolla SurfBoard Cable Modem (SB5100) and a NetGear router (RP614NA) Working directly at the incoming cable termination site in his basement, I cannot get a browser to connect. I have tried hooking the PC (W2K SP3) directly to the modem and through the router without success. I have run the installation wizard provide with the modem as well as the NetGear set-up software. I am getting a port number, which tells me the PC is being recognized by the router. I have reset the router to factory defaults. The router even recognizes the dynamci IP address. The farthest I have gotten is the return of the modems MAC address.

Forgive my stupidity but I am stuck. Where to start?

Any good tutorials on set-up and troubleshooting?

Thanks!

You have the pc plugged into the router, then the router into the modem, right? I just want to make sure, for your description sounds like you have the router coming after the modem.

Ahh, I misread your post. What is the IP your getting on the pc, is it a private IP? You shouldn't need to install the software from the cable company. Can you ping www.yahoo.com from a command prompt? I'm not sure what you mean when you say you are getting a port number.

Yep, incoming cable into the modem, then a patch cable into the router, then to the PC.

I cannot reach any website. I didn't think to open a command prompt window and try to ping a website or do a tracert.

What I meant with the port number is that when the PC is connect to the router, the router displays a port number (lights up) whereas when the PC is not connected, no port is displayed.

Not sure what you mean here.😱

Make sure that the Cables are all Functional.

Many Internet Cable providers use the MAC number of the computer that was first connected to the Cable system as a form of authentication (Password).

So first connect the computer Directly to the modem and make sure that it is working. If it is not working directly for sure it will not work with the Router.

If the computer alone connected to the modem does not get Internet, check the Network Setting, and call the ISP.

Could be that there is a MAC number confusion.

Once you make it work with single computer connected the system through the Router and Clone the MAC number of the computer?s NIC to the Router.

Since a Router comes with his own MAC number you ISP thinks that someone is Stealing Signal and disconnect. However, all current Cable/DSL Routers provides a menu entry that will allow you to Clone the MAC number of the Registered NIC. Thus the MAC number of the main computer's NIC becomes the MAC number of the Router.


Q: What MAC number I should Use?

A: The one of the computer that works well when it is connected directly to the Cable Modem.

Q: I heard about MAC trucks, but do not know how to find Network Card MAC?

Link to: How Do I Find my IP and MAC Numbers?

Link to: Using IPCONFIG Command Line Utility, and or Winipcfg (Wntipcfg) GUI Utility to find Local Network Info (IP, MAC).

Q: How to Clone the MAC number to my Router?

A: Unfortunately I do not have the manual of all Routers that are out there. You will have to read your Router?s manual.

I use Insight and both times I have hooked up a new cable account, I have had to call the cable company. The first time they had the wrong MAC number off the modem. The second time they could not tell me what was wrong other than it was something on their end ...

Always worked after I called though 🙂

Give the cable company a ring.
