ATT 2wire modem will not work. Red light on power button.

its the power  cord.  the fail after a year to 1 1/2 yrs.  get a new power cord

I just went thru this problem. I lost the Internet Signal after almost 2 years, the top power light was solid RED and the "wireless" light was solid green , all others were off. I talked to an at&t tech and told me to try to test the 2Wire Modem/Router with the power cord from a PSP (playstation portable) which have the same voltage, 5.1 Volts. I dont know anyone who owns a PSP so I went to Game Stop (the used video games store) they were nice enough to test it, they got lots of used cables for the PSP. Once they plugged it in, the power light was blinking green, so I knew the power cord is the problem. I thought of just buying that used PSP cord for $10 but the guys at the store that might as well get the original replacement for $10, at the AT&T store online. Ordered it. Got it. I noticed that it has now 2.2 Amps , the old ones have 2 Amps, hopefully this one last longer with the 2.2 Amps. When I plugged it in, all the lights started to blink green and got the Internet Signal in about a minute as the router reset itself back. To make a long story short (too late) IT IS THE POWER CABLE!!

--Hopefully all this babbling will help someone-- Good Luck!

I had this problem. The solution...the Sony PlayStation Portable (PSP) power supply is 5V 2amp. Works Perfectly as a replacement. It even has the correct plug. (Thanks to Marco at Play Again Video games in Corpus Christi for going through the junk video game power supply drawer)

My daughter had the red led only on her 2 wire modem--after reading the feedback here I checked the output voltage of the power supply which is supposed to be 5.1vdc---it was fluctuating around 3.5vdc -- much too low.I have an electronics backround & opened up the power supply & found 2 capacitors (a 1000uf 16vdc &470uf 10vdc) that had decreased in value by 75%.I replaced these parts and the power supply works normally now.The power supply is made in China(what isn't these days)& I have experenced this poor quality of these electrolytic capacitors from China many times in other electronic equipment.The modem was no more than 2 yrs old.

I just got back from the AT&T store and paid for a new modem because they said mine was defective (Red power light / green wireless light). I tried the new power cable on the old modem and it worked immediately. I then got on and found this website... Hopefully they will let me return the new modem so I can bo buy a $10 power adapter - REDICULOUS!

AT&T should issue a recall for the power cords. Perhaps they have, but I have no communications on it. I have been on the line with AT&T technical support many times over the last two years on this issue. They told me they have no knowledge of recalls on equipment that they are providing technical support for. I told them that that was very unprofessional and that it should not take over a year to take decisive action to address a well known blunder which is entirely their own fault. So, one solution is for AT&T to do the right thing - they should fix the problem that they created and use the technical support line (and email, etc) as a means of communicating this solution to the millions who are experiencing or may experience the same problems we have with faulty AT&T equipment.

I had the same problem with the modem. I got a Power Adapter 5VDC - 2000A from RadioShackfor $32 and solved, again I have internet. ATT knows the problem with the adapters but what they want is to sell the modem for more than $100 including S&H again!! they are... something else!!

I had the same problem (red light), tested the transformer/powercable and it seemed ok. I bought a new modem/router ($100) and found that my old modem/router worked fine with the new transformer/powercable I returned the modem to ATT bought a 5V transformer from an electronics store for $29 hooked it up and everything was fine (green light). The guy in the electronics store said he sells about 50 a month just to replace these crappy transformer/powercable

Both my brother's modem and mine did the same thing within two weeks. In both cases it was the power cord.

Just had the same problem with my 2wire (red light, then dead) and thanks to this website avoided getting a new modem. New problem: The ATT online store has the replacement power supplies on back order, there is nothing and they can't even tell you a delivery date! Best of all: After you place an online order and get a frustrating email they don't let you cancel the order. So DON'T ORDER THE POWER SUPPLY FROM ATT. I saw that Amazon has 2 links to outside vendors for the original, but would you trust this piece of cheap **** again? Better go for the PSP power supply or something more expensive from Radio Shack....

Get a AC adapter from a place like GAME STOP ask for the Sony PSP AC adapter it is only $16.00 everywhere else I looked was selling them for $30.00.

If you know what your router key code is (you should have it written down somewhere) you can try a "hard reset". On the back of most 2wire router/gateway cases is a small hole about the size of a paper clip wire. Straighten out a paper clip, and push it into the hole until you feel a "click". Hold it there for 30 seconds. This will reboot the routers OS. WARNING!! If you don't know all the setup items, such as the key code, user name and password, etc, don't do it!

Perfect! Thank you to all who posted regarding the AC Adapter solution to this issue. I went to GameStop this morning, purchased the PSP AC Adapter for $15 and the problem is solved.

Shame, Shame, Shame on AT&T!

I had the same issue. It was working fine and suddenly around 12 midnight it stopped working. I thought ATT must be doing some maintanence. Next morning the issue kept on. Call ATT and they said that with the power right staying RED my modem is gone bad and I need to buy a new one and transferred me. The other rep on phone said I had to buy and I was unhappy so asked them to put me back to account specialist. I was surprised as the account specialist told me that it could just be faulty adapter and to try with Radioshack. I was surprised that ATT rep suggested this. I hung up and used my IPhone to do a search and came across this thread as well. Lucky for me I had a spare Radioshack multiple volt power adapter which I had in my car to return. I plugged that In and voila... all is back. Thanks to this thread and ATT rep for suggestion.

Thanks a lot for the post. It saved me $100. In my case, the power light was flickering between red and green - it was not solid red. And wireless light was solid green. No other lights were on. Got Sony PSP AC adapter from GameStop and 2WIRE modem is now working as great as ever before. It cost me $14.99+tax.

You guys were 100% correct, the power cord is most definitely the issue.I went to Gamestop and purchased the PSP powercord, plugged t in and the router works perfectly.I brought the router with the original cord and the new PSP cord to the AT

thank you guys for all these posts!! i'm just having the problem right now and my modem is about 2 years old, i already called att and they said that the modem is the problem, but after reading these posts its probably the power cord! i'll run to gamestop tomorrow and get the psp adapter, hope it will solve my problems!! thanks guys!

Everyone's posts are great here. Basically, as we all not AT&T are all ASSH*OLES. Go to your nearest Game Stop, Exchange, or I guess Radio Shack. Pick up a 5v adapter, mine is Sony, cost: $10. Recycle your old adapter at your nearest Staples (they also recycle plastic bags). Plug here in and WAH-LA. Save your self a new modem and the time it takes to troubleshoot over the phone with the morons over at AT&T. Good luck!

I did the PSP adapter and can verify it works. Thanks to the guy that came up with that, I didn't have the $100 for a new modem. AT

att 2 wire modems power light was red and wireless light was green called att and they said modem was bad.....(i have had mine for a year and a half) but did a little research and all it was the power supply witch i went to Game Stop and got a power suppy (psp hand held game system willfit and correct output voltage) a 15.00 dollar fix compared to att 100.00(modem)+20.00(shipping)=att is trying to make some money....

I had this same problem - my modem worked perfectly for 2 years, and one morning it just stopped working, witht the power light staying red and the wireless light staying green. Bought a PSP power supply, seems to work fine now.

what if the dsl light only goes from green to red and none of the other lights flicker or go off. could it still be the power supply? because it doesn't seem like it's losing power.

Same problem, same solution !! I had in my modem the power light on red and then it was dead!!! I just plug the psp adapter to my 2wire and save me a lot of troubles!! Thanks to everyone that post their comments about it!!!

I had the exact same problem with a modem that was only 6 months old. Went to my local Game Stop and bought a PSP replacement router, it fits the port and it's also a 5 volt adapter, like everyone says. My modem is now working perfectly!

Same issue, and a new $10 power supply was the fix! Did NOT need a new router.

I had the red light on problem. Power supply was the issue. $10 from the AT

Had the same red-light problem, and sure enough it was the power cable. I picked up the USB AC converter for PSP at Gamestop for $14.00. It was up

Completely true! if your 2WIRE AT

okay this isnt exactly a solution but im having the same problem but i just bought my 2wire like 3 months ago and most of the solutions on here is that if your 2wire is about 2 years old this happens mines is only a few months old....so why am i having this probleem ?

when

same prob here called my buddy he had a xtra one changed the power supply
and and im up and running again

My 2wire was blinking green, then red intermittently, then back to blinking green. This seems to mean it's not working or it's resetting. AT&T went through troubleshooting steps with us, and finally said that we need to buy a new modem through them, which is over $100. We had already bought one a little over a year ago and now it doesn't work again. In my experience, modems don't expire as quickly as these crappy 2wire ones.
I searched online for a cheaper solution. One possible problem is that the power adapter is crappy. Gamestop's PS2 power adapters do not work with the 2wire anymore, it seems. I searched at Radio Shack and Best Buy - same result. AT&T seems to have wisened up to this and changed the connector size. You have to match up the connector and the voltage. I bought a 2wire power adapter on Amazon for about $15 (shipping already accounted for) and plugged it in. Our internet is now working again, saving us over $100.
THANK YOU.

I had the same problem. $10 replacement cord solved the problem.
