    Even though my computer comunicates with the router could it still be the card?

  • futhermucker Jul 30, 2009

    Also it still lets me go to the modems ip address but says the adsl line is not connected.

  • futhermucker Jul 30, 2009

    The phone line goes to the modem then modem to router then to the cpu but the only time it(the modem) works is when the cpu is off.

    Ok I did as you said with no success. I pulled an old network card from an old cpu put it on this one and nothing. It has to be some issue with the power. When the power supply my cpu is plugged into is turned off I get a connection. As soon as I switch on the power supply the light on the router for my cpu lights up then I power the cpu on and when it shows the windows logo the light on the modem flashes. The only way to get a dsl connection is to power down but only when the power supply is shut down about a minute after does the modem light stay solid. Is it posible I forgot to connect a harness from the power supply to the motherboard (one small square on motherboard one large rectangle and one to each hard drive/cd drive)or the replacement power supply doesn't completly fill the gap the way the old one does, I was only able to install two screws. Maybe its not grounding correctly.

    I also tried turning the power supply on with the computer ethernet unplugged. I get the same result without even turning the cpu on?

Hello,

It sounds like your network card was damaged by a power surge, most likely what brew the power supply too. When you power up the PC now the network card tries to start and kills the network line going to the router, when PC is off the card does not short and the router works like it should. You should be able to put a new network card in a open slot in the pc and connect that one to your router.

I hope this helps, If so please rate my solution.

    Hello again,

    Does your phone line go connect to your computer such as to a phone modem? Something is interrupting the dsl data line and that is what is causing the blinking lights. Your previous info stated that when you turned the PC on the modem lights went red and when the pc was off the light went back solid and you could connect with WIFI. How are you getting to the router? re you using the same PC or are you connecting wireless?


  • Buddy Mcsparrin Jul 30, 2009

    First I would unplug the PC from the router and turn the router on, check the light and see if they are green and all looks ok. I would bet that if you then plug the cable from the router back into the pc when its on that the router lights would start flashing red. That would show what was first described, replace network card in PC.

    Try that test and let me know.

    Buddy

When i connect the dsl cable to it the dsl light starts flashing green then red


Put tinfoil over your splice connectors and filters as they leak signals that totally confuse your modem. Never leave any bare wires, I tinfoil the entire modem to prevent the neighbors from hacking me. I don't use wireless, only CAT5 ethernet cable.

Tip

Troubleshooting DSL Modems


Ever look at your DSL Modem and wonder what all those lights mean? Why do some flash, while others remain solid? What if your lights are different colors? How do you tell if your DSL Modem is working correctly?<br /> <br /> Each light on your DSL Modem represents a function. The light is an indication of whether that function is working properly. Sometimes the placement and title of each function can vary by modem manufacturer, but they are pretty standard in interpetation. If you look closely your modem, you might find that each function is labeled in small print to help identify them.<br /> <br /> A standard DSL Modem has a light for power, internet, ethernet, link and wireless connection. A healthy DSL Modem will have a steady green light that does not blink or flutter for all features other than internet, ethernet and wireless. A flashing or fluttering light indicates movement and useage. When you are connected to your DSL Modem wireless, the light for this feature will blink indicating a connection and/or active useage. If the internet connection is working properly the color of the light will be green. If the connection is working but experincing a problem the light can turn to yellow or orange. If the connection fails, the light on the DSL Modem can be red or absent depending on the problem causing the trouble. If your service is turned off by the provider, more than likely the light will be "off".<br /> <br /> If your lights turn a different color, are absent or your internet connection fails try power cycling your modem before reporting the trouble to your provider. Power cycling helps the DSL Modem to reset its connection and repair your internet services.<br /> <br /> If you are using a DSL Modem alone to connect to the internet (no additional router) you can power cycle it by first turning off your computer and then unplug the modem itself from the power source at the wall. Wait for 1 to 2 minutes and then plug it back into the power source and wait for the warm up to finish before rebooting the pc.<br /> <br /> The DSL Modem should go through the normal warm up procedures of blinking lights, making them all stable and solid green ect. You will know when its finished warming up when the features are set at solid green (other than eithernet, internet and wireless connection as explained above). When the modem finished the warm up, reboot your computer and check your internet connection.<br /> <br /> Power cycling your DSL Modem can help keep your connection healthy and running at optimal speeds.<br />

My 2wire has the power light red and the ethernet green and th wireless solid green and the dsl off and the internet off....what can i do


I had the same problem on the Gateway 2701HG-B supplied from ATT for use with their DSL service. From searching the web, I learned these variety of modems apparently have an expiration date on the power cord at about 18 mos to 2 years. Mine is almost exactly at 2 yrs.

I replaced the power cord and now it works fine. You can order the OEM replacement from att e-store or try Radio Shack for a universal cord.

2Wire 473 router problem


Take the modem and plug it into a GFCI outlet. You can find one in the bathroom or the kitchen.

If the power light comes on solid green and the dsl comes on red then the modem is good. Was it plugged into a power strip by the computer? If so, plug it straight into a wall outlet.

If the power light comes on solid red then the modem has hardware failure. I would contact your ISP and have them replace it if it is still underwarranty.

Blinking light on the DSL modem.


Unfortunately it sounds like the modem may need to be replaced. I had the same issue. Even after doing a complete shutdown, resetting all the cables, restarting the modem and then the computer, it still did not work. After you get the modem replaced, I would suggest you get a spare, possibably from e-bay, so if this happens again, you will not be without DSL Service.
