    I have the RCA DHG525 and I am having the same issue. The only light that is on is the "link" light and the rest are off.  I have tried rebooting it and have tried unplugging it for a while and then plugged it back in and still it does not work.   Any ideas?

Either there is no signal to the modem. or the modem is bad. 1 blinking light says it is looking for the downstream signal. Has cable company disconnected you? Can you try modem on different outlet that maybe has active signal for your cable box. Is there any cheap radio shack (store bought splitters inline) these won't pass the channels that some modems work on.

I have no idea why this happens, but unplugging it for a while and reseting it seem to help.

What happen when a adsl line work with a phone but not with a router


The phone line does two jobs. Voice phone which is what it was originally used for and ADSL modem which works at a high audio frequency.
Somewhere between the phone socket and the modem should be a filter splitter. One part goes to the phone and the other to the router. Make sure you have that.
The modem will have a power light and several additional lights. Assuming the power light is on we are interested in two of them; The ADSL light and the Internet light. When you switch the modem on you should first see the power light flash then go solid. Then the ADSL light will flash and then this should go solid. If this light does not come on then you have not plugged the phone wire in properly. If this light just keeps flashing slowly then the modem can't see an ADSL signal on the phone line. If you have a spare router you could try it and see if the ADSL light goes solid on that.
If the ADSL light is fine then the modem has locked onto the signal on the phone line, sync'ed. If not then this is the problem you must solve. Ask your ISP if service is set on your line.
The next light is the Internet light, this maybe a symbol like an i or a world. This light will begin flashing then go solid. It will flash with Internet traffic. This means you have Internet, as far as the modem is concerned. If this light does not stay on then your ADSL account name and password maybe wrong. You can correct this but that's a different question you need to ask.

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 />

Other lights blinking but internet light is blinking for 2-3 times them off all the time so I am not getting internet


On most DSL modems, normal light states are:

Power - Solid
DSL - Solid
Internet - Solid or flashing quickly when data is being transferred.
Ethernet - Only on and flashing quickly if cable attached to it and an active device
Wifi - Solid or flashing with active data transfer

I have a Motorola SB 5120 modem the P/C light is always flashing .At time I can't get on Wi-Fi from my I Phone or my desk in my sons room, and other time i can.What is going on or do I need another...


Hi

The flashing lights (espicially the Internet light) are normal, they indicate activity (Power, LAN, Broadband, Internet).

Some modems suffer from signal interference from other wireless devices in your home and neighbourhood.

Sometimes the problem may be a signal deadspot in your home to do with unseen metal, pipes, wiring or some other aspect of the buildings architecture.

If your modem has a detachable aerial that crews and unscrews, then it might be possilble to buy a larger more powerful booster aerial for it (take the old aerial to the store with you to ensure compatibilty of the screw fitting) that will give you a better signal.

The modem does not have to be sited near a phone socket. Consider resiting the modem to a good central point where everyone gets a good signal, by buying and using Male to Female power cord extensions and Modem cable extensions.

Ensure that your internet connection is enctypted with a private network key and protected by a password, so that neighbours cannot pirate your internet connection and thus use up your bandwidth and slow down or degrade your signal.

I hope this helps.

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....

The internet light is off all others green on the 5100 modem. Also, very slow internet and hard to go to various webpages. Will this correct itself over time or is there a quick fix?


You can try resetting the modem to factory condition.
Turn off the modem from power
Disconnect the modem from the computer
Turn on the modem
Press the reset button using a pointed object, (a toothpick or a pencil)
Wait for all the lights to flash green then release the button
Reboot your computer
Connect the modem to your computer

Everything should work fine.

If the problem persists contact the service provider.

Thank you for choosing Fixya
