SOURCE: 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.

SOURCE: cannot make a wireless connectiio work with Comcast internet

- Once you already configured the settings on your router, and 2nd step that you do now is to power cycle the modem and the router completely for about a minute.
Note:
- You must also remove the battery back up of your cable modem in order to refresh the settings on it.
- After the power cycling procedure, turn On 1st the modem and make sure all the link lights on your modem are completely stable before you turn On the router.

How do I reset mailbox after switching carriers?

If you cancelled your Comcast internet service then your Comcast email is gone. Hopefully you forwarded any important emails to a working email account (or even to a friend you trust) before cancelling the account. On Century Link sign in to your new account then locate and click on Email. There should be a button to click on to set up a new email account. Failing that, call Century Link customer support and they will walk you through it step-by-step.

You're paying monthly fees to COMCAST, correct?
So, telephone them, and get their "technical support" department to help you get it working.

Will this work with Comcast broadband and Windows 7?

This modem will work with Comcast High Speed Internet.
You will have to contact Motorola for drivers for the Windows 7.

It does matter how fast your internet speed is,anything faster than 20meg,will need a Docsis 3.0 modem.

Bought on eBay, trying to setup with comcast. See wireless signal but can't connect to the internet. I got to the configuration page and changed the SSID and setup WEP but the internet is not working.

have you tried connecting an ethernet cable directly to the modem to see if the internet is working that way? Have you considered contacting comcast as they can make sure its on your end or their end. Use this faq to help you. If you need further assistance please let me know.

My Motorola Sb5101 modem will not let me access the internet, the send light constantly flashes and i can't attain any internet connection.

If you have the following lights :
Power light - on
Receive light - flashing
Send light - flashing
Online light - off
PC/Activity - on
Standby - off
Then your Network Access is OFF - modem is successfuly registered but Network Access Control is disabled via DOCSIS configuration file.

Call your internet service provider....

Internet connection issue. Is it setup or internet service

The problem would be comcast. Your connections are setup correctly. The modems do not control the internet traffic flow, they are made to produce maximum flow.
If more people use the internet, the less flow it will have.
Check all internet options settings, and make sure EVERTHING is set to automatic

Using laptop and pc on this router

You SHOULD NOT post your personal details here...

The dx esw5 is not a router, it is a switch so it cannot assign an IP to the second PC.

dx esw manual HERE

Which ever PC is turned on first will get an IP assigned by the modem and the other will not.

My guess is that the service provider for your internet only allows 1 IP to be assigned by the modem.

What model is the modem

I think you need a router to share the internet between 2 PC's

Loss of internet connection

Sounds like a switch before the signal gets to your house. Modems usually don't go out intermittently unless they are overheating. Is the modem in a ventilated area where it can get some air? An alternate is to borrow a modem from a friend to test it. Usually one of your niehbors will have the same service and the same modem. I had my surfboard (from comcast) for 5 years and it was solid as a rock, the spotty services was always at the Comcast switches (at the street or the nearest hub.

Hope this helps
