Cannot access internet thru my arris tg862 modem,authentication problem

SOURCE: how is Arris Telephony Modem installed?

Hi taldrich6 - You have this listed under Arris CM450. Is that what you have?

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

if the power light is flashing then the modem is on battery backup and internet is disabled. plug the power cord into the modem or find a working power outlet, you should be set after that.

Power light flashing=bad

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.

Try 192.168.0.1 or 192.168.100.1. Make sure that your pc is connected directly to the Arris TM602G modem and not on a router.
