Question about 2wire 2700HG-B Router (2700HGB)
MY 1Wire2701HG-B power light is red the only othe rlight on is the wireless. The power supply is good. Any ideas???
A sony psp power supply has the same specs and is a lot cheaper than R/Shack Got mine on E-Bay for under 4.00!!!!!!!!!!!! with FREE shippiong

LESS EXPENSIVE, TECH-SAVVY, FEEL PROUD OF YOURSELF ANSWER.
If you're handy with a soldering iron, crack open the wall-wart part of the power supply ( a dremel is handy here, but you can also put it in a vice until it "cracks" open.- just be careful not to crush the contents!)
Inside, there is a 1000uF capacitor that bulged. Revoved it, and replaced with the same value (check radio shack, or maybe you have an old junked motherboard you can pull it from)
it took me 10 minutes to fix this whole thing back up, cost me less than a buck.

The power supply is the problem. I have seen this trouble 8 or more times with my clients. Replacing the supply will fix it. You can get a replacement here:
Or you can get a replacement at Radio Shack. Your power supply replacement must be 5VDC and capable of at least 2A.

If you have a power light red and the wireless is on and the rest of the lifghts are off..it means the power adapter is defective. if you have a PSP, you can use it for the 2wire 2701hg-b model..if you're going to purchase a new power adapter, make sure its "5.1 VOLTS"

I just had the same red power LED problem on my 2WIRE modem/router this morning.
The root cause is the 'soft-failure' of the power adapter. The tricky part is that it appears to be working properly if you simply measure its output voltage when not connected the modem/router (5.2V in my case). But once plugged in, the voltage drops (in my case) to about 4V. I checked this out by cutting the power adapter cable, which revealed an insulated red wire and green wire (plus a bare copper wire that is likely connected the ground prong of the plug, but not used). If you remove some red and green insulation, you can measure the voltage with a voltmeter while the unit is plugged in. The voltage should remain at ~5.1V, but will drop to perhaps 4V if faulty. Accidentally shorting the red and green wires will not cause a problem - you will not get shocked, and the power adapter should not get damaged. They have protection built in.
An Alternate method to test (without having to cut the cable) is to short the + and - connections on the power adapter. If you have a digital multimeter (DMM) that is able to measure current (i.e. Amps), and it's rated for at least 2A (i.e. there's usually a fuse in the meter to protect it), then the wall adapter can be shorted by connecting the DMM across the wall adapter's +/- terminals while the DMM is in the Current measurement mode. The red lead on your meter will typically have to be moved to a different plug on your DMM, labelled "A" or similar. My faulty unit measured 1.0A, and i'm guessing that a good unit should measure closer to 2A given the rating for the unit.
power adapter: 2WIRE P/N: 1000-500031-000, output 5.1V/2A
open circuit voltage (i.e. unplugged from router/modem): 5.2V
loaded voltage (i.e. plugged into router/modem): 4.0V
short-circuit current (i.e. short the + and - pins on the adapter): 1.0A

The new power source just worked for me as well ... If you dont want to wait for bidding and or shipping just take the power cord to Radio Shack and get one there that has the same power specs.. at this very moment im using my PSP power source and once radio shack opens i will be on my way hope this helps those of you out there see that it could very well just be the plug and is an easy fix..

I had the same problem. I bought a new (identical) power cord on ebay for 10 bucks. It's better than buying a new modem/router. You'll need to make sure it's the same specs. But I have to tell you that by seeing the ease of availability on this power cord, I think 2Wire knows about the defective powercord.

I had the same problem. I got a new power adapter and it fired right up.

Ok guys/gals. My 2wire 2704HG-B also died. Light turned red. Then after a day no power light at all! Went and bought a new dsl modem/router from best pricey buy and found out my new shiny netgear router wasnt having nothing to do with my voip needs. So now, I'm off to radio crack ( i mean radio shack) to get their 30 dollar power adapter replacement(the one with equivelant specs), UNBELIEVABLE. My 2wire router wasnt treated like gold, and only a couple years old. This is a lemon scam, and for at&t's solution to just "buy a replacement from them" is unethical. Venting so others who are in a similar situation can learn from my issues with ATT router the twowire router and adsl modem.

AT&T is not the only one to use this DSl modem. I have Qwest. Had the PS go out, it doesn't work when ALL plugged in. I opened the case, I'm a tech so maybe easier for me, and fixed the faulty capacitor for 50 cents. And has been working good now. It's the heat inside the box that makes them go bad. This is a standard failure for a lot of electronics. If you can solder, give it a try. It very cheap. Otherwise check ebay for cheap power supply! Don't pay $30 or even $20.

Ploblem solved: Go to radio Shack or ???...Gigaware
Universal Gaming AC Power Adapter it takes in 100-240VAC
output 5v 2A , it has (5) Output connectors...the yellow one will
work with the 2wire 2701HG-B... cost 14.99-came to 16.23....
came home hooked it up and worked great

The problem can be 2
1) the power supply
2) the noise of your line, see this
Make sure you have the modem on a phone cable going directly into the wall jack , bypass any splitters or filters they gave you. the phone cable has to be a cat3 cable for best performance and less than 15 feet long.

I just had my 2wire go bad, so I went online and searched. Found the answer right here, thanks a lot guys especially to meestermole2. I like to fix things so I went ahead and opened the power supply, removed the 1000 UF 16volt capacitor and replaced it with another one from Radio shack P/N 272-1032 ($1.59) It's a bit bigger than the one from the p.s but it fits. The capacitor has polarity so make sure that you install it correctly, it usually has the negative sign on the side of the capacitor. After replacing it, hooked everything back up and the modem fired right up.! I fixed it for less than $2.00 bucks. Ohh... It's a little bit hard to get the p.s open but with a small screwdriver you can work it around and pop it open, no biggie.!!!

Had the same problem with my 2wire modem. Tech Support told me that the modem had a hardware failure and that I need to purchase a new one. The cost was $108. After reading some earlier post, I went and bought a PSP AC Adapter for $15 and it fired right up. Please don't fall for their BS. It's the power supply. Also, seems like most will fail around 1.5 years of use. Good luck!!

Att will try to sell you a new modem. Your problem is the power supply. To older ones were 2A the newer ones are 2.2A.. Radio Shack will try to sell you one for $30 if they have it. Went to two stores and they both said they could not keep them in stock as there were people in every day looking for a 2Wire replacement. (RADIO SHACK TAKE NOTE)
Well I went online and for $10 + $4 Shipping had one in 4 days. Ebays Net direct Was the answer. Easy and fast

Even though the power supply is testing good, it's testing good with no load. The voltage will drop when the power supply is under load of the DSL modem. You need a new power supply (wall wart) and you will be back on your way again. I've seen replacement power supplies at Radio Shack & ebay.

Just wanted to say I followed the advice of meestermole2 and toritochis and replaced the 1000uF cap. Cost $1.59 at radio shack. Extremetly easy fix. Hooray internet! Boo AT&T!

We ran into the same problem yesterday: red power LED on a 2WIRE DSL modem. AT&T sell a replacement power supply on line for $10, but the AT&T Phone Store doesn't carry it by itself; they only sell the modem w/ power supply. We went to Radio Shack, and they tried to sell us a multi-voltage power supply with many output adapter plugs for $37. So we went to our local Fry's Electronics and got a multi-volt power supply for $19; that solves the problem.

I had the same problem. After 3 years of FLAWLESS operation, my DSL suddenly displayed the solid red power light and solid green wireless light. Did a little internet research and the overwhelming stated cause was a bad power supply. So, I tried meestermole2's solution. Opened the wall wart easily enough. Sure enough, a bulging capacitor. We unsoldered the old, soldered a new capacitor in (what are the chances we'd have one in the garage?!) and voila, it was working again. Thanks to everyone for the input and especially meestermole2. You rock!

Thank you ALL for your input to this problem. Saved me an awful lot of money and aggravation. Will be replacing power supply and if that by chance should fail I will next replace AT&T! Calling them is like losing an hour of my life, I'll never get it back and have to listen to crappy music and crappier sales pitches....blah!

I know this is an old post but if you end up here like I did, I have an answer, albeit a bit technical. We have the old 1000 series 2Wire DSL unit, the power supply for it FAILED the first year. I replaced with my own power supply but it has just failed (5 years later). It seems this router sucks more and more power over time. It will keep recycling once the input voltage falls below some threshold. Now keep in mind I am an Electrical Engineer but if you have minimal skills you can do this: Use a AC/DC converter that can output 8 to 12 Volts at 2 amps. If neccessary, add 3 amp diodes in series so the voltage to the router is 8 to 8.5 volts (no more!) under load. I route the + to the center of the power plug. You may have to cut off the old plug and use it becuase the size they used is not common. Ironically, I had an old Atari power supply from the 1980's game console and the plug on it is a match! I am using 5 diodes in series to knock down the voltage but works like a champ and will likely last another 30 years (a lot longer than the cheapo Chinese OEM power supply)!

Got a new power and that did solve the problem. Until a month later and the red light is back ... :(

I too replaced my 1000uF capacitor, which I stole from another wall wart. Cracked open the power supply and saw the bulging cap. 10 minutes later I was up and running again. Funny thing is I just argued with att and got them to give me a modem for being a loyal customer. They had to charge me for the modem but gave me a year of $10 off per month to cover the cost and lifetime $10 off per month for the trouble to keep me as a loyal customer. This is about the 4th or 5th device in my house that I have replaced a bulging capacitor and it has come back to life.

I never would have believed this until it happened to me. Many in my family work for att and one works in DSL repair. I asked if they had ever heard of this and they said no. The one that works in dsl repair said no way, if your power supply is bad no lights will go on. Well long story short. I bought a PSP2 power supply at Raido Shack, same voltage as the att modem. I saved myself a 85 dollars by just replacing the power cord.

Mine just popped the 1000mF capacitor too. Opened the Power Supply case and viola its all bulgy. My Radio Shack was out of them so I borrowed a PSP power supply and I'm good til it comes back in stock.
