ARRIS Modem + D-Link router = no internet

I have cable modem with an Arris modem and we tried to use our D-Link 2310 router but it doesn't work we can't get the net (I ain't using the wireless and don't care about it btw). I've changed the router twice and switched the modem once and it didn't change anything.

Plugged directly into my computer the modem provide internet just fine and my modem has been tested at a friend's place (who's with the same ISP) and it work perfectly.

I call D-Link they say that the problem is my modem, Videotron (my ISP) says that the problem is my router. They all evade their responsibilities and I really don't know what to do anymore. I've tried everything thing I found on the net but it doesn't help.

    I couldn't get an Arris tm502g modem to work with a DI-524 router. I followed the advice from 'ohms' (clone MAC address and re-boot router), worked perfectly. (Hint: on the DI-524, the button for cloning the MAC address is on the "Home" tab, then hit "WAN" among the left-hand buttons. You might then have to scroll down a little to see the MAC info.)

    Prior to that, I was working solely through the DI-524 wizard and getting nowhere -- process kept coughing up errors (internal error, 'not connected to a di-524 router', can't get to internet) and I couldn't figure out if I had a bum router, bad modem, wrong info from the ISP, etc.

    So if you're experiencing this: skip the wizard, go straight to the GUI and try ohms' trick. Even if your router already has a MAC address assigned, give it another go.

    Also: Updating your firmware might be a good idea. Go to your router's manufacturer site.

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.

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 to secure my d-link wireless adapter with my Arris 550a modem


To make your wireless router secure you need to use your browser and type in the router's IP configuration address.
Then you need to change the default Admin password,
change SSID and turn off SSID broadcast,
setup the encryption (use WAP or WAP2 if your wireless card supports WAP) if not use WEP 128 bit encryption
and for added protection use MAC address filtering.

Link light blinking


On these cable modems the link light is supposed to blink when you are connected to a router/pc. If you are hooking up a wireless router new you need to power cycle/reset your cable modem before you hook up the wireless router so that way it can refresh its ip address.
