My 2wire 1000Hw router keeps restarting

My 2wire router keeps on restarting when I plug it into the wall. The first light (power Light) goes green after a few seconds, then the Broadband link goes green after a few seconds but then the, local network light blinks green one time and the whole process starts all over. I have no chance to go into the settings and reset the router. Also note that if I use the original adapter that came with the router, the router doesn't even turn on the lights. Instead it makes a whining noise, which you can barely hear. So I am using an old phone adapter that works great and actually turns the lights on. I made sure all the connections were good. I also called my ISP which is ATT and they told me that its out of warranty so I should get a new one. Any help would be appreciated, thanks.

    I don't have an ammeter to test it, and it doesn't get hot at all even if I leave it with the plug on for 3 to 4 days. I'm talking about using the phone plug not the original plug. So what do you think is it bad?

    Sounds like your solution would've definitely fixed the problem. Too bad I threw away the router back in 2009 haha. Well at least it'll help others. Thanks for the reply.

I have had three of these do the same thing. It is not the router causing the issue. It Is the power supply. I replaced mine with one from MPJA. It is a 4 Amp supply and I had to change the connector but total cost is $6.95 plus shipping on the power supply and $2.00 for the connector. Specifically inside the power supply is a 1000 uf cap that is bad and leaking. When the wifi and the DSL are both started the current is too high and the voltage drops causing the reset. Replacing the power supply fixed all three modems.

I have a D-Link that had a similar problem. The power adapter that came with the unit wouldn't work, so I modified a PC power supply to power my router, so I could test the router. A component in the router had failed, (in fact when i powered up the router, this component got so hot that i couldn't touch it) and that's why the original adapter would not work.

Most likely a component has failed in your router. If you want to veryify this, use an ammeter to test the current draw of the router. If it exceeds the rated wattage then the router is bad

    I wrote that a component inside the router gets hot, not the router itself. I explained to you how to test the router, if you don't have the ability to test it, then obviously you need to buy another one.

Check your current rating on the OEM power supply.. I think your power supply needs 2 amps at 6 Volts. The cheap ones at radio shack are usually only 2 ma.

Try the following steps:
1. Disconnect the 2wire gateway power adapter.

2. Reinsert the power adapter directly into the wall socket.

3.Remove any power strips or surge protectors temporarily to ensure that these items are not preventing the 2wire gateway proper operation.Note: Make sure that you are using the power adapter that came with your 2wire gateway.

4. Plug the power adapter into a different wall socket in another room.

5. Press the red factory reset button if available.

6. If the power light is still red, then you will need to replace the 2wire gateway.

My dsl light is on green but my power light is on red. After a while no lights are on. My router is a 2wire that's about a year old

These 2Wire devices are known to have their wall-wart weaken over time. Although you can measure the proper voltage coming from the wall-wart, when you load it with the DSL modem, the actual voltage drops giving you the red power light. The green DSL light may or may not be accurate while the DSL modem is not getting the power it needs. Look online or go to a store like Radio Shack for a replacement wall wart.

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.

The middle light is the light for internet services. If it is flashing that means its looking for a dsl signal, if its solid orange that means it needs authentication information (IE: username/password entered into it) and if its solid red that means you have no signal at all. What I would recommend is first check all the phones/alarms/satelite dish systems in your house and make sure they all have dsl filters on them before plugging into the wall, since this will cause an intermittent dsl connection. If everything is fine then call your Internet Provider and have them do some line tests for you to see if the service is having problems.

Modem keep rebooting.

It sounds like you have a bad modem. Have you tried to plug the device into a different power outlet? This will rule out that it's a possible power issue in the outlet.

If no change by trying a different outlet I would replace modem.

Hope this helps.
