Be sure that your cable company has enabled your internet. Power down the cable modem, power down any routers and computers. Start cable modem first, after internet connectivity is indicated, power up the router (if you have one) and then power upi the pc

SOURCE: i have an arris tm602gct and cannot connect thru my netgear

Can you connect if you are directly wired into the router?

You may want to try using a ball point pen and pressing the reset button on the back of the arris. Let it reboot and try again.

Some netgear routers come with the wireless disabled out of the box, so you need to be hard wired when you run the CD or if you try to connect through your browser 192.168.1.1

There's a reset button on the back of the modem. It'll power cycle it. That should work and if it doesn't make sure everything is connected and tightened.

The Cable modem must be disconnected from the computer. You cannot use USB and Ethernet at the same time.

1. Turn off power to the Cable Modem and the Netgear Router. Do the same with the computer.
2. Connect an ethernet cable from the modem to the router's WAN (Internet) port.
3. Connect another ethernet cable from one of the remaining 4 LAN ports on the router to the computer's ethernet port.

4. Now power on the Cable Modem ONLY. Wait for the modem to sync up with your service provider
5. After about 2-5 minutes power up the router and wait about 1-2 minutes.
6. Now power on your PC.

Check and see if you have internet access. If not you may have to uninstall any cable modem software related to USB connection. if this is the case, then you may have to repeat steps 4-6.

Since most cable internet providers do not use proprietary connection settings, your internet connection should be up and running without changing any settings in the router or modem.

If this does not resolve your issues, we can continue to work with you.

Setting up xbox live


ARRIS modem is a phone/hsi modem. What youll need to do is first turn power off on xbox then unplug the power supply from the back of the Arris modem and unscrew the coaxil/cable wire from the back of the modem for about a minute. Then plug in the power cord to the modem wait another half minute then screw in the coaxil/cable wire....wait for the lights to come back on make sure the online light is solid green not flashing and follow the ethernet cable (Looks like a thick telephone wire) and make sure you have that ethernet cable seated/snapped into the ethernet port on your xbox. Then turn the xbox on and do connection test. FINISHED..IF it's still not working make sure you have Internet service from your provider and if using a router bypass it at first see if you can get onto xbox live without the router. If you can with just connected directly to your arris modem without the router involved. If you do want to use wireless contact your router manufacture and or xbox support at 800-469-9269.

I have my main computer set yp with arris router


  • You can use both Ethernet and USB interface to connect two PCs simultaneously with one cable modem.

  • If you plan to go wireless (and maybe connect more computers), you have to purchase a router to split/share the internet connection coming from the modem.

I have a arris tm602 modem, HOW DO I CONFIGURE MY NET GEAR ROUTER FOR INTERNET CONNECTION


Cable modems bond to what they are plugged into, so you have the modem plugged into a computer and it is working fine. Then you want to unplug the ethernet cable from the computer and plug it into another device such as a netgear router. Then you find no matter what you do it will not work.

Now normally to break this bond to the computer so that it will bond with the router you would simply unplug the electrical power from the cable modem, wait for it to sync back up with your ISP's CMTS, power up your router which you would have connected via the internet or wan port, and you would be up and running.

You may have even did this with your Arris TM602. Why isn't your router pulling an IP address? The reason is simple, pulling the power cord did not really remove power since the modem has battery back up.

In order to make it release its bond to your computer, so it can bond with the router you need to either push the reset button on the back of the modem while still powered up or remove its battery pack while unplugged from power.

So try again, this time push reset on the modem. This question was posted in January so I am sure buttercup is all fine by now but maybe this will help someone else.

How do i connect a Linksys wrt54g2 to a arris cm450a


Your modem is capable of linking up to a router. What you do is take an ethernet cable and run it form the internet port on your modem to the internet/wan port on your router. From there you connect your pc's into the LAN ports on the router (typically labeled 1-5) if they are hardwired or you connect wirelessly with your laptop. You need to also power cycle/reset your modem when you plug your router in.

ARRIS Modem + D-Link router = no internet


when you are on Cable Internet with a "modem" only connected directly to the computer, what the ISP see is the computer's MAC Address (command prompt -> type ipconfig and hit enter).

put a router (which has it's own MAC Address) in-between and the ISP wont let you cause it sees the router not the computer.

check physical connection: cable modem -> router -> computer(hard wire for this troubleshooting)

access the d-link gui and locate the “Clone MAC Address" button (supposed to clone the computers MAC Address - verify if it's the same), save settings & reboot the router.

Switched to cable(arris modem) can't set up network


cable dsl same thing. Did you switch providers and get new modem from them? If so. Just delete previous netowrk and install new one let pc discover new one. Also, with your router you got a disc. It should install correctly. Perhaps it is previous network that is hindering you.
