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

Since I switched to a bundled cable pkg. I've been unable to set up my network. My netgear router can't seem to work with the arris modem, and my belkin adapter can't pick up the signal. It's driving me nuts as I've tried everything. Cable says it's the router, they say it's the modem, they say it's the adapter etc. Cable said their system is too fast for my router. Help me!

    I have one pc hard wired to the arris modem. I am trying to set-up network with a router and wireless adapter (netgear router, belkin adapter) everthing was working until I switched to cable from dsl. Now I'm unable to setup the network.

    Thanks, I tried that but it still does not work. The new modem is a telephony one one with a battery back-up so I believe that this may be the problem. Since, I unplug, (to power down) but it may still not fully be down to reconize the netgear router since it has a battery back-up (2 hrs).

Providors use mac address to identify the modems used on their systems. That is why, if you add a wireless router, the router software should have the ability to let you copy the MAC address of the modem. That way the providor only sees one mac address.

This will work i suppose.it did for my aris cable modem.

Remove the Backup battery
Unplug power from the modem
Plug the new router into cable modem (while the modem is still off)
Wait for the router to have its lights runnning.
power the cable modem.
put battery back in

this worked me when i switched from my buffalo router to dlink and tried also with directly to my computer and it let it work.

i guess the cable modem remembers mac addressses or something and if it doesn't match then it won't go through (but that's a guess)

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.

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.

I just switched to TimeWarnerCable/Internet. How do I connect two PC's to the Aris TM602G Modem? Then How do I connect my Laptop? Bob


You connect the Aris to a wireless router with say 4 LAN ports.
You connect the PCs with LAN cables to the LAN ports on the wireless router and install a wireless card in the laptop if it does not have one.
To secure your wireless network from unauthorized access, please click on this link and follow my instructions :-

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.

Unable to set up wireless router


Shut down your computer, unplug the cable modem and the switch. Connect all three - computer to switch, switch to modem. Make sure that the ethernet cable between the router and the modem is in the router uplink port and that the computer is plugged into one of the four ports that look alike. Wait 30 seconds - plug in the modem. Wait another 30 seconds, plug in the router, wait another 30 seconds and boot the computer. Open a browser and see if you have internet access. If you still don't, then try to check the browser by typing 192.168.1.1 into the address bar of the browser. That should give you the browser sign in screen. The Linksys default is to leave the user name blank and type admin for the password. That should give you access to the router so you can check the settings. If this doesn't work, document carefully what happens and post again with your results and we'll try to go from there.

Cannot connect router to arris modem


You will have to unplug your computer from the modem to plug in your router. Then you will have to plug the two computers into the other ports on the router. If this doesn't help. send more information on how you have it set up now, type of router and type of computers (desktop or Laptop, Wired or Wireless).

Wi-Fi isn't working


This could be a duplex issue. When you log into the belkin does is assign you an IP address? Have you used a ballpoint pen to reset the EMTA since you have connected the router?

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

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.

I cant get out to the internet when I connect the netgear router.


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
