Arris tm502g doesn't recognize Netgear n600

Not real network savvy here. Have been running my cable modem direct to PC with no issues for 6 months. Have a 2nd computer and now I need to use set up a Netgear N600 that I had from a while back. I'm not using this wirelessly. Have all the cables hooked up. From the Netgear configuration screen, it thinks my cable modem needs a fixed IP address - that's what it says when I run the wizard, though everything is supposed to be dynamic. Through phone calls with TimeWarner (ISP), the modem isn't recognizing the router. At my wits end so any help would be appreciated.

    In the meantime, I found a solution. I had to use the computer mac address. I guess this is called 'cloning'? The advice also said to use port 4 as the port hooking my pc to the router though I have no idea. All I know is that it worked, and in the meantime thanks for all of your suggestions. Sounds like some of the cable ISPs require this workaround - something like they 'register' your PCs MAC address on 1st usage or something like that. Anyway, thanks again.

Did you run the driver CD for the Netgear N600 ? That is the first place I would look. Or it is possible that your Netgear N600 is not working properly. There are some very inexpensive small USB dongles that do work very well, I would try that as well. They run in the less than $10.00 range at places like Ebay or Amazon.

SOURCE: ADSL ISP provides same address for IP and Gateway

Can you manually change the WAN IP on the router?  If so, give it an IP like 123.12.167.5 and set the gateway address to 123.12.167.1.  If it asks for a subnet mask, give it 255.255.255.0.
If she has a Linksys router, you may need to change the operating "MODE" on it.  A lot of Linksys routers have 2 modes of operation---Router mode and Gateway mode.  For her configuration, make sure the Linksys is in Gateway mode.  This will fix the NAT problem.

Cheers!

SOURCE: I am trying to add

I understand that you are facing trouble with the setup of the router WNDR3400 with your cable modem. I would suggest you to follow the below steps to reset and reconfigure the router:



RESET:


With the help of a paper clip, press the reset button on the back of the router for 20 seconds (please refer to the label on the bottom of the router for reset button location). Release the reset button after 20 seconds and turn off the router. Turn the router on after few seconds.


CONNECTIONS:


1. Connect an Ethernet cable from the modem to the WAN port of the router (isolated port).

2. Connect the computer to the router using any one of the 4 available ports. Please make sure that there is no direct connection between the modem and the computer (either using Ethernet cable or USB cable).

3. Power off the modem and the router after making the connections.

4. Power on the modem and wait for the lights to come on and then power on the router.


RECONFIGURE:


1. Open a web browser like Internet Explorer, Mozilla Firefox or Safari.

2. Access the router's GUI by typing http://192.168.1.1 or http://www.routerlogin.com.

3. When prompted for Username and Password, please enter 'admin' for the Username and 'password' for Password.

4. Click on 'Basic settings' from the left menu and select 'Use Computers MAC Address' from 'router MAC Address' section.

5. Click Apply.

6. Once it updates the settings then power off the modem and the router. Power on the modem and wait for the lights, then power on the router.


I hope this information allows you to resolve this issue.


Regards

Anand

Arris TM502G is cutting out when d/l heavy bandwidth.


Three things in the system. Modem, router, computer/xbox. You changed the router and problem still exists. The computer/xbox is calling for the data but the modem is stopping it even though your provider doesn't see it stop. Change the modem. Borrow one if you can but I suspect it is going glitchy.

Cant connect my presario r3000 to netgear n600 router


First unplug the power cable from your modem. Then press and hold the power button of your modem for at least 1 minute. Then plug in the the power cable and wait until all the lights become stable. Then you can try to go online to check.

If after this step you will not be able to go online then contact with your ISP provider.

I think its the modem that you need to upgrade. Comcast is already running on DOCSIS 3.0 system. The SB5120 modem that you have is a DOCSIS 2.0 modem. You may need to have your modem replaced with a DOCSIS 3.0 modem like the Motorola SB6120.

Hi,

There could be a couple of causes for this issue. Your internet could be degraded when it gets to your house causing disconnects. You will have to contact your Internet Service Provider in order to have them resolve this issue. Normally, they will replace splitters and may even replace lines outside of your house. You could also be having problems with the modem directly. The may replace this. You could also try to upgrade the software on it. Click here for the update page for Arris.

Typically, I recommend you unplug the router, plug the computer directly in the modem and see if you still have the problem. If you still have the problem then you know it is just the modem. If the problem resolves itself then you know the most likely culprit is the router.

I would also recommend that you update your router firmware as well. Do a google search for the brand name of the router and go to the companies website, look in the support/downloads section for updated software.
--If possible, try a different Ethernet port on your router. You may have a bad port.
--Take out and reinsert all Ethernet cables on your network. Loose cables can cause disconnects.
--If possible, replace the Ethernet cables. Bad cables can cause this.

Lastly, you could be having an issue with the Network card(NIC) on your computer. Network cards are either built into the modem or external(a card you insert into the motherboard). Using the process of elimination and the steps above, you can hopefully narrow down the problem to one specific component of your network.


Let me know if you have any questions.

Where do I find the WEPkey for Arris TM502G? The question is posted all over the internet, but no real answers.


The WEP key is a encryption key that is configured in the wireless settings of the wireless router. This setting is then applied to the wireless card in the computer so it can connect to the wireless router.

I have arris tm502g modem n want to hook up 2nd pc wont work


You need a router or network switch to share the single connection from this cable modem. Wireless router if you're so inclined. Comcast is about to jack the rental rate for that modem from $3.50 to $5 on January 1, at least in Atlanta.
