Re: My Mdoem's ethernet and usb lights are off

Assuming you using ethernet to connect the pc to the modem: how about checking your ethernetLAN card on the pc if it's integrated with the motherboard you can enable it from the bios settings if it's an expansion card it sounds like you need the most up to date driver which can be downloaded from the card manufacturer's website if you have access to internet on another pc. assuming your pc is connected to the modem via usb: reinstall the driver for the modem . another thing you can do is buy a usb to ethernet adapter which are available for under $5 on the market one end connects to the usb port on your pc and the other end is ethernet and this should work .

Motorola Surfboard Cable Modem User Guide
The user guide for your Motorola Surfboard cable modem can mean the difference between knowing how to locate and diagnose problems with your connection or staring angrily into a maze of blinking lights.

The user guide provides information on properly setting up your cable modem, understanding the indicator lights and troubleshooting problems before you have to call your Internet Service Provider.Connecting Your Modem

Your Motorola Surfboard cable modem must be connected to your home's coaxial cable connection.
Connect the coaxial cable from your cable outlet into the "Input" jack on your cable modem.

If your modem is wireless, it will connect to any computers and wireless devices in your home through the wireless signal sent from the modem.

Wired Internet connections require that you use an Ethernet cable to connect your cable modem to any supported computers and devices.
Understanding the Front Panel

The front panel of your modem is your key to understanding the status of your cable modem.

The front panel features "Power," "Send," "Receive," "Online" and "Link" lights, each of which displays information about your modem.

The "Power" button will display a solid green light when operating normally and will turn off when there is a problem with the power supply.

The "Send" and "Receive" lights will transmit a solid green or blue color when data is being normally transmitted through your modem and will blink when it the modem is scanning for an upstream or downstream connection.

A solid green "Online" light indicates that you are connected to your Internet Service Provider, while no light indicates that the Internet connection in your home is experiencing problems.

A yellow "Link" light indicates that a computer is connected to your modem with an Ethernet connection while a blue light indicates that a high-speed Ethernet connection is being utilized through the modem.

Configuring TCP/IP

The Transmission Control Protocol/Internet Protocol provides the basic foundation for establishing a local network and a connection to the Internet. The TCP/IP can be configured in the "Control Panel" of your Windows computer. Open the "Network and Sharing Center" from the control panel and double-click the "Manage network connections" option. Right-click the network connection displayed and select "Properties," then select Internet Protocol Version 4 and open the TCP/IP properties menu. Select "Obtain an IP address automatically" and "Obtain DNS Server address automatically" from the TCP/IP properties menu and click "Ok" to save your TCP/IP settings.

Many technical issues with your cable modem can be resolved by power cycling your modem and the computers and devices connected to it.

To power cycle your modem, unplug it from the power supply for 10 to 15 seconds and reconnect it to the power supply.

Restart all of your connected computers and devices while your modem is power cycling. Problems with the "Send" and "Receive" functions can be the result of a poor signal being sent to your cable modem. Tighten the coaxial cable connection to your modem and contact your internet service provider if problems persist.

PC link light is off while Internet and cable activity lights' are solid. Can not connect to the internet. Can it be fixed? If so, how?

The PC link light is your indicator if there is a device connected to the modem through the ethernet port. If its off, then you may need to check the connection once again whether it be a PC connected hardwired to the modem or a router. Replacing the ethernet cable can also help because it might also be a defective ethernet cable. As long as the internet and cable activity lights are both solid, its ok because that means your modem is receiving the signal from your provider.

I have a DHG536C Cable modem from Comcast Does is have an internal router so I can use a simple Eithernet switch or hup to connect 2 computers or do I need to use an external router?

The DHG536C is a pure cable modem. You will have to purchase a router to establish a network with the two computers. Alternatively you could connect one PC to the modem and have a peer to peer LAN network between the two pcs. The PC connected to the cable modem will need to be on all the time. You will need a wireless or a LAN card for each of the 2 computers.

If you wnat to buy a separate router you can select something from this site.

Maybe the laptop is configured by default to look for a wireless signal through its wifi drivers, or a different previously installed modem. Go to your Computer/Control Panel/Network Sharing Center and set up a new connection there so your computer knows what to do.

So that means its working well and connected to the ISP' server. What is your connection? Is it ADSL?
First make sure that all light have the color of green. If they are Flashing with color RED that means the property associated with the light is having a failure.
Here are the description of Colors and Lights.
Modem Light state: Unlit Flashing Red Flashing Green Steady Green
Power Light
Modem is not getting power - no light Modem has failed POST - Red Power is on - Steady Green
Ethernet (2nd Light)
No Ethernet link detected - No light Problem with ethernet port or cable - Flashing Green Modem has detected a successful link to a PC or router - Steady Green
DSL (3rd light)
ADSL sync signal is not detected - Red Modem is trying to synchronize. - Flashing Green Modem has ADSL sync and is ready for PPPoE session traffic - Steady Green.
Internet (4th light)
Modem has given up or isn't configured to initiate the PPPoE session - No Light PPPoE initiation has failed or PPPoE has been terminated. - Red Initiating a PPPoE session to Internet - Flashing Green. Modem is ready for Internet traffic - Steady Green.
Note: This light sometimes not working even if the connection initiated.
Normal DSL traffic flow - Flashing Green. Steady traffic flow - Steady Green.
Solving problems.
Case1: You have to connect your machine to the Modem Via the Network cable. Plug the other side of the cable to your Machine. (Not the modem port. Network card port.). Case2: You have to make sure that you have installed the Network Card drives. To check that you have to use Device Manager. Follow these steps. Hit Windows key with R In the "Run" box type devmgmt.msc In the right hand side check whether the network card is installed. If it has a yellow exclamation mark or a mark with red that means you haven't either installed or its having a device/driver problem.
Case3: If its fine then what you have to do is to check your network settings. Heres how: Since you haven't specified the Operating System I m including the Windows XP method here. Not much difference in other Operating Systems as well.
  • Get the Control Panel.
  • Go to Network and Internet Connections.
  • Go to Network Connections.
  • Check the Local Area Connection.
  • Right Click and check "Status".
  • If it says connected
  • Check the Duration and Speed(100 or 1000Mbps).
  • If the settings are fine go to "Support" Tab.
  • Check whether the Machine has received an IP Address. Which is often in the range of for Siemens Modems/Routers.
  • If you see an IP Address which starts from your network card was unable to pick an IP Address from the DHCP router which runs in the modem. (If you run a DHCP in the machine you have to configure to stop leasing IP Addresses to your machine from the Router/Modem. You can try the "Repair" button below and it will try to Release and Renew your IP. If it fail either you have a problem with your network card or Modem/Router (Could be the cable also).
  • If you still see the IP Address which starts with 192.168 the connection with your Modem is fine.
  • Next: Right Click on the Local Area Connection again.
  • Go to "Properties".
  • Double Click on "Internet Protocol (TCP/IP).
  • Check the settings.
  • The settings should be "Obtain IP Addresses Automatically" and "Obtain DNS Server Address Automatically". (But if you know the router's/Modem's IP Address you can configure it and you can give a "Static IP" to your PC as well. It must not be the Router's / Modem's IP and must be in th SAME SUBNET. If router uses you can assign it as
  • Then Apply the Settings and go to the "Status" again and then click on "Details".
  • Except Wins Server all others must be populated with values in 192.168 range. Check the "Default Gateway" Setting. Its very important that you have pointed the machines Default Gateway to the Router/Modem.
  • Final Check:
  • Go to the "Internet Protocol (TCP/IP) again and click on "Advanced".
  • Check IP Settings (first tab) too make sure DHCP is enabled on you machine.
  • Go to "Options" tab and Check TCP/IP Filtering. Click on properties and make sure that the Filtering is not enabled. If it enabled make sure your network adapter Permits all routers traffic in to the machine.
By following these options will let you surf the internet.
Check for the behaviors of indicators as well.
Case 3 :Browser settings
In the Internet Explorer go to: Tools -> Internet Options ->Connections -> LAN Settings -> Its fine if any box is not checked. Or you can check the "Automatic Detection".
Last thing is If you have a Firewall or Antivirus Suite Please make sure that you are not blocking adapters and traffic/application. You can try to disable Windows Firewall and check whether it works as well.

troubleshooting a network is a multiple step process.
1. Establish that your modem is working properly, and plugged in. As per the diagram shown here:
  • Your "Cable link" light should be on (signifying that the outside cable is properly connected to the router)
  • Your "Internet" light should be on (signifying you have an established Internet connection)
  • And, most importantly, your "PC Link" light should be on (showing that at least as far as the modem is concerned, it is detecting that the computer is plugged in to it.
2. double check to make sure that the network cables are seated properly, and plugged in all the way. the PC link light should give you an indication for modem-side- the LED light around the network cable jack on the laptop should give you an indication PC-side.
3. check on your laptop for any security software that may restrict new networks from being detected and disable them to test. For example, Symantec or Mcaffee Firewall can sometimes block a "new" network from being detected.
4. Completely shut down the laptop and unplug the power cord from the modem. Plug the modem back in. Wait around 3 minutes for the modem to initialize and do it's thing- then turn on your laptop and see if this resolved your issue.
If this doesn't work, you may want to try other things, such as resetting your network, and removing/re-installing your network adapter drivers.
