There are no drivers to operate the modem as a USB device. Using a crossover cable (one should have come with the modem), you should be able to connect to it via the Ethernet ports on your computer and the modem.
My RCA DCM425C from Comcast had the same problem when I came home Saturday, 11/14/09 (coincidentally the same day you posted). Had been working fine - cable TV still works fine including On Demand, etc. The Internet light was blinking. Occasionally I'd see it try to work from one light to three or four, but it always came back to one. Called Comcast, they said their side showed "no signal". Sent out a tech today. He replaced the cable modem, reprovisioned it (I guess if I had a backup ready I could have done the provisioning over the phone maybe?)), everything's great. Lasted about a year and a half. When I logged in via http://192.168.100.1, it said it was still in Step 1 of 5 ("Tuning"), and the logs showed a whole bunch of errors on Saturday that stopped after that. Diagnostics would always freeze the built-in web server and require reboot.
While I am no expert it sounds to me like you got a faulty modem. A lot of cable componys will reuse old modems, that where given back after the service was terminated. Sometimes they try and reuse one that was given back because, it was faulty. You can request a new one through your cable provider
There's a lot of layers to what can go wrong, generally speaking you should be able to get online if two conditions are met: You are connected to your wireless network, and your modem is assigning an IP address to your router.
Once you know you are connected to your wireless network (you should be able to see the correct network name when you put your mouse over the computer icon in the lower right - assuming you are using Windows), you can generally fix most situations where the modem is not assigning the router an IP address by resetting the devices in the proper order, here's how:
1. Unplug the power cord from both the modem and the router 2. Wait 1 full minute 3. Plug the power back in on the modem 4. Wait for the Cable light to go solid 5. Plug the power back in on the router
This will solve the vast majority of issues. If it does not, double check to make sure the ethernet cord from the modem is going into the proper plug on the router. Usually this is going to be labeled "Internet", "Modem", or "WAN", in stead of a number.
If even this does not resolve the issue, feel free to give your ISP a call. While this may be a problem with the router, most ISP employees are at least willing to do minor preliminary troubleshooting, and will often have access to advanced tools to help them see what the modem can see.
If the ONLY light not illuminated is your PC link light then that generally indicates a physical disconnect between the modem and the laptop. If you can get the PC link light to light up when connecting to any other device (computer, router, anything), then you are most likely looking at the ethernet jack on the laptop being burnt out. Otherwise, try swapping the ethernet cord. If a different ethernet cord does not resolve the issue and the PC link light does not come on no matter what the modem is plugged into, you are looking at a faulty ethernet jack on the modem.
usually the connection of a router to the modem is made by selecting to get an IP automatically ...and it will do so ..The only issue is to see if the 2 devices not have the same Ip address from factory so that they are not in conflict ..If they have ..just change the one in the router.. The issue is that you didnt managed to make a internet connection directly in the modem either..This is your main concern ..After you make the modem work it will work with the router too cause you do not need much settings if it takes the You will have to enable the wireless so ...and the ports will take IP addresses in order.. Sop ..first see whats wrong with the modem ..If it is a provider preset one ..than remove it from the power plug .,..and plug it back after a while ..and it iwll get back to work ..or call the ISP and see whats wrong ..You will not be able to make it work until you have internet connection in the Wlan port of the router.. here are instructions for connecting a router to a modem .. http://compnetworking.about.com/od/wifihomenetworking/ht/access-routers.htm http://www.microsoft.com/athome/organization/wirelesssetup.aspx http://www.youtube.com/watch?v=wW81ZdxI4Ic
1. try pressing the internet on/off button on the modem. 2. check if the screw on cable is firmly connected on both ends. 3. check all screw on cables going to wall outlet are firmly secured 4. try bypassing any splitters if any
You will need 2 ethernet cable to set it up
Tha first one will go from the ethernet port in your cable modem to the ethernet port of the router mentionned Modem.
The next cable will go fron one of the port of the router to the ethernet port of your Computer,
This second cable is placed temporarely to be able to do set the routers settings,
After this is done insert the Cd that came with your Belkin router and it should guide you through the different setting pages of the router.
Use Network preferences to verify your TCP/IP settings and that Built-in Ethernet is your primary network interface.
Follow these steps if you are using Mac OS X v10.5:
From the Apple menu, choose System Preferences.
From the View menu, choose Network
Be sure that "Built-in Ethernet" has not the status Inactive listed below the entry in the list of network ports.
Make sure Built-in Ethernet is the selected, or primary, network
interface: Click the action button (gear icon) below the list of
network port and choose "Set Service Order...".Services can be dragged
to change order. Services are listed with descending priority.
Select a network port in the list of port to configure it.
first click start in the computer then click run then type CMD then the dos modebox will be seen then type ipconfig then you will see ip adress of the network to which you are connected then type ping the ip address if the pinging is ok then your laptop is comunication with the router if no pininging or ip adress right click my computer then click properties then hardware then device manager and check wether the network adaptor is marked if marked reinstall the driver and restart the computer
I would do a factory reset on the modem, there should be a red or white reset button of the back on it, Just push the button down with a paper clip or something and hold it down for 10 seconds and release. This should completely reset the modem to factory settings, if it is a internal hardware problem then the issue is should be handled by the manufacture i dont recommend opening a cable modem. Changing the power cable is were i would start if the reset fails.
hope this helps, feel free to reply with any questions.
Hi, carm243. Thanks for your question.
It sounds like your modem needs to be reset. You want to unplug the AC cord from the back of the modem, wait 15 seconds, plug it back in, and restart your computer so that it can obtain the new information from your modem. Watch the lights on your modem. You want to make sure that the "Internet" light blinks while the modem restarts, but goes steady after you restart the modem.
As long as your modem is functional, that should resolve the problem. If this does not solve the problem, get in touch with your internet provider and, assuming you are renting the modem from them, ask them to send a replacement.
Best of luck!
