Question about 2wire (1000-000057-000) Modem
Definitely the power cords!! I had the same problem with all of my three 2Wire modems, and as soon as I replaced the power adapters with the generic ones I purchased from Radio Shack, the problem solved.

The modem is a Gateway 2Wire model 2701HG-D. Its function is to handle the high frequency data carrier that rides on top of your ordinary telephone wires to provide internet access. It has four ethernet ports and one USB port in addition to the telephone connector. QWest has said there have been problems with it and they recommend that you purchase a newer model for $100.
Ours failed yesterday with a bunch of green lamps glowing steadily without the normal blinking. The lady was about to go downtown to purchase a replacement when I figured out how to open the box with its four springy plastic bending tabs that you can see looking through the cooling apertures.
What I found was an internal operating voltage of about 4 volts which was well below the 5.1V printed on the power brick. When I ran the modem from a laboratory grade 5 volt source it seemed to work drawing about 1 ampere without any connection to the phone line.
Measuring the 5 volt supply that came with the modem I saw 5.2 volts but when loading it to 100 milliamps or so it dropped to 4 volts. It was definitely out of spec. Replacing the brick with another brand rated at 5 volts, 2.2 amperes solved the whole problem.
A failing power supply usually turns itself off but in this case measuring its output with a voltmeter would result in a conclusion that it was OK. Not so. You have to measure it under load which is a bit harder to do.
So. . . Don't rush to buy that new modem the way QWest says. Consider a replacement power brick. Positive 5 volts on the center of the connector with 2 amp capability. The original power converter used a three pin grounding plug for the AC source and the ground was connected to the negative side of the DC output. That's not normally done and does not seem to be necessary. It would make more sense to connect to the telephone company ground but that wire may not be available in the 6 pin telco socket.

And. . . after cracking the shell of the power brick the input aluminum electrolytic capacitor showed typical deformation of the round aluminum end. That kind of failure is very much a part of my life these days. Sigh.

I had the same problem and it turned out to be the power adapter. I thought this was too simple but I went to Radio Shack and bought a new one and everything has worked perfect since.

AT&T doesn't sell just the 2wire power cord. They charged me $60 for a new 2 wire modem. When I received it I took out the power cord and connected it to my old 2wire and it works fine. If your power led on your modem is red it could just need a power cord.

I don't see how this can be a power supply failure. It's more likely something in the modem. I had the same problem with my AT&T provided 2Wire Gateway (actually not provided... I paid $100.00 for it :( ). I bought a replacement unit at Best Buy and haven't had any problems since.
One other possiblity is that with the devices you purchase from AT&T, they can remotely control / access the unit. Not sure what they're tracking, but I know that I like my privacy :) . With this unit they can't access it at all... and the speeds / performance are excellent.

Fairly EASY solution! See eBay: 391663683701
This is a 5 Volt 3 Amp supply for $7 including shipping!
3 Amps assures more than enough current from the supply... so it won't be overloaded.
WORST case is the NEW connector may not fit? If it's a no-fit cut BOTH connectors off and "carefully" strip the wires. Use a METER (or ?) and BE SURE your connections gives you +5 VOLTS to the CENTER pin!
SOLDER your connections and tape well. Now TEST your routers for proper operation... just to be safe, RESET your routers too.

2701HG-B Power Supply REPAIR! P/N GPUSW0512000GD1S THIS FIX WORKS (at least it did for me)!
As more of these great modems age, I suspect more people will experience this same POWER SUPPLY failure.
And who knows what other random modem problems will manifest as the voltage sags as the power supply capacitors age? In my case the Modem would not power-up at all.
A rubber mallet quickly opened the power supply with ease and I could see that one of my caps vented ~ or bulged out of the top...
I replaced BOTH caps and I am back ONLINE!
* Here is what I did... taking note of the polarity first, I carefully CRUSHED the two caps and that left me with two 'posts', still soldered to the supply board. The posts made installation of the new caps SO easy.
This method works great for other cap/component repairs too and many times saves pulling the entire board from a chassis!
* I measured the output and there was a solid 5.2 VDC, but without a load.
* Under load the voltage dropped to 2.4 VDC!
* As long as I was in the supply I replaced BOTH caps.
* The caps are 1000uF 16VDC caps and again, the 'crush' method worked out quite well.
A hot glue gun worked great for replacing the cover on the supply. I suppose DAP would work well too.
I hope this helps you and I remain...

If the power light stays on and the ethernet light stays on, to me it means that there is power supply to your modem and your ethernet light has connections from the modem to the PC. If both 2 wire modems is plugged simultaneously to one Broadband socket, maybe only 1 modem may receive the DSL signal because for 1 broadband line, only 1 digital signal to a modem is allowed, th modem who gets the DSL dynamic signal from singtel may get the internet access and the other 2 wire modem will not get any DSL light and Internet light at all.
