I ran into the same problem; not many people can seem to find a power cord for these things.
I went to Radio Shack, and was told that no such replacement cord exists anywhere. I had a hunch that this guy was full of poo, so I went to the Radio Shack across town. Lo and behold, they had what I was looking for.
Just take your 2wire modem into the store and ask for a 3-7.5v 2A AC adapter. They may be hard to find, but they are around. Don't forget to make sure they give you the correct tip for the modem.

Hope this helps,
Jon

All lights flashing


Unless the electronics is broke you seem to be having a wiring related issue. Besides a loop then a short in cable or at a port.

Verify no apparent physical stress displayed on unit or cabling and the correct power supply.

One test for bad electronics is by removing all wires, then look for bent & touching conductors in any of the ports from a poorly crimped cord damaging the port. Try to straighten back into shape - 8 per jack or once the touched eliminated if meta fingers bent my not be able to use that port and check the cable ends for cause and don't use.
Without any cords return power. Only the power light should remain on after about 3 seconds. Any other light display says problem and after verifying correct power supply call it toast - it broken.
If only the power light is lit then connect the 8 conductor (4-pair) Ethernet cable from the cable or DSL modem. That port should light if that device is alive. Note: No telephone RJ-11 size 2 or 3 pair cords, if it fits in a telephone jack you got the wrong one and can damage a port physically. RJ-45s used in Ethernet
are noticeably larger.
Assuming no strangeness in the other lights with the cable/DSL modem connected add one cord at a time to the other ports. Stop and remove any that caused/causes the initially observed condition that is the problem leg; try a different cord and examine the problem cord for physical damage (cuts, tears, squashed blemished area, ends pulled such that conductor open, or two or more wires shorted on an end)
As to internet connection try with only link to Cable/DSL modem and one cable to a PC and then see if the PC is obtaining an IP address via DHCP filling in the interface settings. If Windows "ipconfig" if Mac OS/X or Linux "ifconfig eth0" at the command prompt in a terminal window. Ping the entry for gateway, if no lost packets the connection is sound PC through e-switch to modem. Enter as new problem with modem type and PC operating system if this is a problem after the wiring is straightened out.
When the switch is working correctly Power light is steady ON and Port lights are mostly ON but blink with traffic down that leg.
Does this help?

Red power light, green wireless light, no internet access. Have done the reset and the power off. Nothing works.


I had the same problem on the Gateway 2701HG-B supplied from ATT. From searching the web, I learned these variety of modems apparently have an expiration date on the power cord at abotu 18 mos to 2 years. Mine is almost exactly at 2 yrs.

I replaced the power cord and now it works fine. You can order the OEM replacement from att e-store or try Radio Shack for a universal cord.

2wire gateway


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.

Part numbers on the failed power brick

P/N 1000-500031-000
Part No GPUSW0512000GD1S
Input 100-120Vc.a 50/60Hz 0,15A
Output 5.1V DC 2A
Class 2 Power Unit
Made in China

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.

RCA DCW615R WIRELESS Cable Gateway , Factroy Installed Firmware needed.


I had the same issue with my RCA DCW615R. First time my ISP Comcast flashed it back to the old version. This time I could not find anyone who new how to do that. I used to have the software and I have searched the net. Seems they provider RCA does not have it.

This time I called Comcast because I noticed that the 192.168.0.1 brought me to their software update. They supplied me with the user name and password. I was able to get into the firmware and change all the settings using the new firmware. I think the only reason they gave it to me is because my printer is a network printer and it would not work unless I could access the firmware.

The old 192.168.100.1 does not work anymore because that was Cable Modem mode or CM mode. The new address 192.168.0.1 does work but you will need the user name and password from your ISP, this is RG mode or residential gateway mode.

Liked the old firmware better but they both do the same thing. Seems the Gateway works better with the new update. Still I would like to find the old firmware not sure why RCA doesn’t have it.
