2701HGB modem - dsl light flashes red

Plug power cord into back of modem and then into an electrical outlet. At this point you should see the lights on the front of the modem beginning to come on.


Check the front of the modem for a solid green DSL light. If the light is still blinking, allow a few more moments before proceeding to step 5. A blinking DSL light indicates a break in the network and will require the help of your service provider if it does not turn solid green.


Open your internet browser and type the default gateway into address bar. The default gateway will be provided by your service provider. Newer model 2Wire modems automatically direct you to the installation instructions when the browser is opened.


Click on "Run System Setup Wizard" in the lower right-hand corner. It may require the system password. This password will be provided by your service provider.


Select your timezone and click 'Next.'


Enter your ISP provided login information and click 'Next'. This should authenticate your credentials on the network and complete the installation.

The flashing DSL light means that the modem isn't seeing the DSL signal on the phone line it's connected to. This might be due to modem failure, but it might also indicate a phone line problem. The most common trouble I run across is an unfiltered device connected on the line that interferes with the DSL signal. Other than the modem, all devices (phones, fax machines, security systems, etc.) need to be connected to the line through a filter. Check to be sure something hasn't been connected without a filter. Sometimes a phone gets moved or a new phone is added that gets plugged in to a handy jack without being filtered.

If you can, try connecting another modem to the line. You may be able to borrow one, or find one at a resale shop. I see them quite often for only a couple of dollars, leftover from people changing to FiOS or cable service. This can help determine if the modem is responsible.

One final possibility: your DSL service has been cut off. I've had two cases where loss of DSL was a phone company issue that they needed to fix at their office. (One following some wiring work done in apartment building, the other when service was mistakenly disconnected from the wrong customer.)

This kind of trouble can be a headache to solve, but it can be solved. Good luck and thanks for using Fixya!

Please loot at his post, i replyed to his question.

Is that second location also a DSL line? You may have to consult with AT&T to see if the DSL line runs to that second location.

What are you trying to accomplish? By adding a second modem, you essentially create two separate networks. Why not use a switch and connect it to the first modem, which would allow you to connect more PCs.

wireless signal is not from ATT but from the router or modem.
the distance between is line of sign. approximate max distance is 500 ft. you should have not problem connecting it.
The only obstacle is walls, trees, or any other thing between you and the modem.

*if the DSL light on your modem is blinking..
TRY: using different filters// check physical connection
IF: not resolved call ISP for a trouble ticket for their line department
*if all the lights constantly blinks
DO: purchase new modem, maybe deffective already or check if modem still under warranty so provider can replace it

NOTE: plug 4100 modem directly to the back of the computer tower without the linksys router and check if light status still the same...
HOW: cable connected from back of modem shud be plug in directly to port at the back of PC tower.. completly remove linksys and turn linksys off..

Hi,

If you are att customer, you will be charged $60 only if there is problem inside your premises, otherwise they wont charge you.

Is there any phone connected with your DSL line? if so is it working? if its not working, contact customer support and tell them its not working

If the phone is working, you have to check the connections between the phone line to the modem. As the DSL light is blinking red, its the problem with line and not the modem.


Take care

hi,there are a lot of possibilities y ur dsl light wont stop flashing red, 1.could be hardware failure,2.defective lead light for dsl,3.or line issue on the network...i strongly recommend that you contact your isp or att provider so that test would be done by their tech support,...basically you have checkd all inside wirings n as you have said you even tested the nid already...have you tried changing the dsl cable or phone cable? have you tried using another modem? were you using a filter for your dsl? you have to consider also other emi/rfi or electronic interference....but most probably you might try upgrading your modem n see if your gonna get a steady dsl light...the ethernet plugs has no effect on the dsl light...its just the cable connection or line issue or defective modem...i hope this will help, pls feel free to ask if you need further astnce...

Hi. I will not repeat the check the phone line and resetting comments as it's now redundant.

I always have a spare modem as a line tester.

I've seen several 2700HG-B 2wire modem/routers burn out and every single time it's the DSL signal or modem portion that is burnt out. Even if you have two or three phone line surge protectors these 2700s are prone to shorting out unless you have a direct signal splitter DSL setup.

Here are a few things you can try to confirm if the 2700 is no longer functional on the DSL signal light problem.

#1: Turn on (plug in) your 2700 without the phone line plugged in and wait. If the DSL starts flashing red then there is a hardware problem in the modem/router.

#2: Plug the phone line into the 2700 while the dsl light is flashing red. It might take about 3 seconds however it should start to flash green and let it flash for about (usually) three minutes. If it turns red then the 2700 is indeed damaged.

#3: If you can enter into your modem using the http://2wire... and check the connection status. The first two status lines should read attempting to connect and no connection.

Hi, Rob just studied ur problem.Iam a tech which handles this kind of issue. I talk to verizon,at&t,bellsouth,qwest daily for such issues. Well i can suggest u onething u can get the efficient speedstream 4100 series modem which comes with a 1 yr warranty. And also checkout with verizon clearly abt ur distance from the central office.Bcos might be ur dsl circuit may be not technically feasible i:e NTF. For further clarifications plz get back to me.
