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.
Thank you guys saving me $$$. 2Wire Power light red, ATT said out of warranty, need to buy a new modem. I was lucky to find this forum before going ATT store. A $1.59 capacitor 1,000uf/35V (a bit large though) from Radio Shack (P/N 272-1032) just works fine now.
BTW, the old dead capasitor (1,000uF/16V) bulged on top.
The power adaptor and ATT sucks, Hooray Internet!
glad it saved you $$. i love fixes like this, makes you feel good, you know?
Enjoy!
Thanks, Thanks, Thanks........The power supply capacitor was indeed the problem even though it was putting out what seemed to be a good output voltage....changed it out and everything works great now.
Prior to fixing...the red power light was on, and the green wireless light was on. The no load voltage from power supply showed 5.1V-ish. Used a vise to crack case(squeezed on opposite corners slowly and repositioned and squeezed on other two corners to crack without affecting board inside.) I then plugged it back in and checked 'load' voltage on the across green and red power wires..it gave 4.8V-ish. So, everyone, dont be fooled by the no-load voltage being ok when in fact the power is dropping under load to cause the modem to malfunction. The capacitor in question was the one(1000uF 16V ) laying over, near the power cord on the board. It basically looked fine and not really bulging but I changed it out with a new one(RadioShack 1000uF 35V p/n 272-1032 $1.79). Fired it up and rechecked load voltage and it stayed at 5.1 this time. Modem fired up all green and now im writing this as thanks 5 minutes later on my computer which has been down a week!
BTW....AT
Suspecting the power supply, I cracked it open to check the loaded voltage. I then immediately spotted the bulged 1000 uf 16V cap. I am very familiar with these cheap Chinese capacitors from my work as a computer tech. Replaced this one with a good quality 1000 uF 10 V and all is fine now. It kept a little bit out of the landfill anyway.
Same problem here..Power lite Red and Wireless lite green. Cracked the wallwart and found the 1000uf capacitor bulging. Replaced it with identical part from Fry's for $1.99(#1005343) and now it works good! PSU lasted three years before it died. Thank you for all the help comments. I would never had guessed it was the power supply since it read a no-load voltage of 5 volts.

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:
http://store.att.com/catalog/productdetails.asp?ProductId=1000-500031-000&CategoryId=catMRG
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.
my specifics:
model: 2701HG-B
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!
I had a friend with this modem that called yesterday saying it just quit working. Dim red power light only, no other operation. Voltage under no load 5.08v but under load dropped to 4.25v. After reading this post I opened the power supply and found the same thing, bulged 1000uf 16v capacitor. Replaced it with one from radio shack that cost 1.79 and the modem works fine now. Qwest was going to charge them 99.95 for a new modem, and tried to sell them a lot of other services while on the phone. Thanks for the help, and saving my friends almost a hundred bucks!!
2-Wire 2701HG was working fine, then it I lost connection, looked at it, sync light was out, power light was blinking green.. unplugged it, plugged it in, it started to go through it's cycle..
never regained sync.. then after a few more attempts to reset it, I saw the power led turn red a few times.. blinking green, then red, then it would cycle and turn green again, them red...
Finally it went solid red and the wireless light was on green steady. Aparently a dead givaway for the PS to be bad.
Called WIndstream, Oh your modem is bad.. $99.00 for a new one, they dont carry the 2-wire anymore... oh well no thanks..if anything I will get one from Ebay.. so I started searching for forums such as this, finally decided to take the power supply apart, saw the 1000uf 16V cap that is mentioned in these articles.. it didn't look too bad, barely could see the top had swelled out a bit, so I scrambled looking for a cap to de-solder off of something and replace this one..
I had an old PC power supply, and sure enough it had 2 16V 1000uf caps..took them off, replaced it into the 2-wire PS. No go.. Solid Red Power Led - Wireless light on green. Well.. then I realized that donor PC power supply was dead.. these caps may be dead as well..they were, I went and found an old 12 volt PS I had from some flashlight or something.. cracked it open (a vice works well for this, just enough pressure to get the top to pop) and I found a 1000uf 25V cap.. well not too much different, it looked perfect, so I tried it.. Hooked up the 2-wire modem, power led was now flashing green.. so I hooked up the dsl phone wire, my ethernet, plugged the modem back in, and it did a equipment cycle check, power led came on solid green, and it trained on the DSL signal, works perfectly again. Thanks to all who helped me with this.

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.
Worked yesterday, RED power LED today
I replaced the power supply with a $5 PSP supply i purchased on e-bay. Works fine now. I attempted to repair the old power supply with a replacement cap, but it only worked for about 2 weeks then started to fail intermittently. STILL spending $5 for the replacement supply was ALOT better than paying Qwest for a whole new modem!

Wow thank you, same thing just happened to me. Borrowed my buddies psp charger now it works just fine. Just bought a psp charger off ebay for 5 dollars shipped.
Oh yes! Same problem with Power LED turning off and then changing to red and green randomly. Followed the advice and opened the AC Adapter and sure enough, the 1,000 uF electrolytic capacitor was bulging slightly. Voltage was 3.9 Volts when powering unit. I found a 680uF/25V electrolytic cap in an old notebook supply, unsoldered it and replaced the 1,000/10V cap in the 2-Wire Adapter. Plugged it in and the power LED stayed green. Voltage was now 5.1 Volts while under load! Thank you whoever found this problem as you saved me about $100 and a lot of heat from the wife and kids if they couldn't get online.

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.

Usually answered in minutes!
1) I tested the power supply.
2) The unit was working for a year so there is no need to use other cables. I installed another DSL modem and router so I know the cables are OK. The unit simply will not power up. I opened it up and there is nothing internal to replace or fix. I guess it is dead. So much for 2Wire.
same problem, red power light, green internet light. 2nd one I've purchased in about 3 years. it was working this morning came home after lunch and it was in this state.
Same problem. It's been working fine for over a year with no changes in the wiring setup. When I couldn't get online, I saw only the power and wireless lights on. The reset button had no effect. I unplugged it and plugged it back in and now none of the lights stay on. They flash briefly with initial power. My power supply has 5.25 volts with no load and 4.3 volts when plugged in to the router.
same
Same problem here also with 2 Wire Modem from AT&T model 2701HG-B
Went to log onto internet and unable to connect. Noticed solid red light on for the power and a solid green light for wireless.
Have had since March 2007, same setup with no change to cables or connections.
Tried reset button on back and nothing changed, called AT&T tech support they are sending me another gateway no charge. They told me to throw out the old one. Looks like they only last a short time.
same thing ...red power light, just wanted to configure it for client, not connected to adsl line, just put settings in for her , for plug in and go. After turning on and off 20 times finally got green flashing light. configured , thought id power off to recheck, then same happened , solid red power light. Again flicked on and off , different sockets etc, green again, then tried off and on again solid red, not been back up since...client has been waiting 2 weeks for this router.
Solution #1 Actually worked for me, I got a different power cable, from 2 wire (old wired modem, changed from the new wireless) and voila!
Thank you sooo much!
Same problem.
2Wire is dead.
I have the same as issue red power light and green wireless light I have called AT&T spend about 2-3 hours to get the run around. They want me to pay $79 for a replacement modem.
The router turned red on the power mark. I tried plugging it in again, after a couples of minutes, but no go. I can't get to use the internet a lot now.
I have a similar problem except that no lights come on. The router was working fine on Saturday, and when I went to connect on Monday it was dead. The lights will flash briefly at times when plugging in the cord, but will not stay on for more than a second. Could this be the power cord?
same problem, working one day the next day nothing. Power light is red. Called AT&T they said I was out of luck and to buy a new modem. Modem was two years old. Wasn't as lucky as Gl barron, no new free modem for me. I will try a new power supply.
I tested the power supply also. It was at the stated voltage. When I bought the new modem (same model), I used the old power supply and IT DIDN'T WORK.
I plugged the new power supply into the old modem and IT WORKED.
2wire 2700HG-B lemon. Wish I read this site prior to calling ATT re Red power light problem. ATT first said circuit- no way! Then had us plug into a bathroom GFI and still red. ATT said 2Wire modem died and it only has a 13month warranty (since Feb07) and you need to buy a new $79 2Wire. When asked why it fails so fast, ATT said, heat, dust wear it out. But no heat or dust here! Husband's on his way over to Radio Shack to try the power cord suggestion (thanks for the tip!). I'll post back if that works. If it doesn't we'll switch brands. Also, per ATT DSL customers have a backup dial-up connection they can use if DSL fails.
I have the same problem. Bell was working on the line...likely zapping all the people who switched from Bell. I called Teksavvy and said my profile was 8GB (too much) and was told that Bell likely was working on the line...the modem was fine the night before. Funny thing, when I signed onto Teksavvy, the first thing that Teksavvy did was to lower my wildly profile down from 8GB...so it was already changed before. Teksavvy told me that likely they were playing with the line...I suspect them to be getting back at those who switched. I'm glad I switched from Bell...F**K U BELL!
My 2 wire router power light turned red, I looked on this web page, I read all the post on here, I opened the wall mart and found a bulged Capacitor, I picked up a new one at the electrinics store and replaced it. It works now. Thank All Of You For Your Help.
