The 3Com® OfficeConnect® Cable/DSL Gateway does not have an internal cable or DSL modem. The gateway router is designed to connect to the Ethernet output from your cable or DSL modem. An Ethernet cable is supplied with the product for this purpose.

Theres no dsl light on the router, its a d link dsl2640b. so i need to know if its broke, the power light is on and the status light but no dsl light and no internet light on router, the pc is showing...

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!

I have a second line for dial up and would like to switch over to dsl through my cable company to save some money can I drop my second line (dial up) and go to cable without any problems. I pay MSN direct...

DSL connection works on the same line provided by company who provides DSL. If dialup line is not provided by DSL company, you can drop dialup line and contact DSL company for DSL connection. If dialup line is provided by DSL company, migrate your internet plan from dialup to DSL by contacting DSL company.

Macbook and I-touch loses wireless connection with versalink dsl

It sounds like the dsl modem and the gateway should be sync'd in the following way:
1. Turn everything off and disconnect the dsl for a bit. Make sure even the wifi stuff is off.
2. Turn on your gateway and let it cyce up.
3. Plug the dsl ethernet cable into your gateway, and to your phone line, then plug in the power to the dsl.
This will cause the dsl modem to "find" the gateway IP address and connect.
4. Turn everything else back on.
This should eliminate all the drops...
Let me knowhow it goes...

My DSL constantly loses sync after it has been on for awhile

If you have telephone devices (e.g phones, fax) sharing with your DSL line, be sure it has DSL filter on devices so it won't interfere with the internet connection. If every devices is properly filtered, disconnect all devices sharing with your DSL line and leave the modem connected to the phone socket with 3 meters phone cable and observe the connection. If the connection becomes stable, connect each devices so you will identify of these devices is using a faulty filter.

Yes i want to find out if a cable modem will work with your dsl phone internet service?

No.

A cable-modem connects with a coax-cable to the cable-company's network, but a DSL-modem connects with telephone-cable to the telephone-company's network.

Lexmark x6150 unalbe to fax phone line is active using dsl

Hey Tony - Did you recently hook this up to the DSL for the first time? This unit is supposedly not able to work with a DSL line.

The fax modem in your AIO is an analog device and cannot be used on an ISDN, DSL, or PBX digital phone service. However, you can connect certain devices to your AIO that let you use the fax function in addition to these digital phone services.

To connect without an unsupported line:
Connect an active telephone cable from the AIO to the telephone wall jack.

To connect with an unsupported line:
• If you use an ISDN phone service, you can connect to an analog telephone port (an R-interface port) on an ISDN terminal adapter.
For more help and to request an R-interface port, contact the ISDN provider.
• If you use a DSL (Digital Subscriber Line) phone service, you can connect to a DSL filter or router that will allow for some analog (rather than digital) use.
• If you use a PBX phone service, you can install an analog phone line for a fax machine.

If this was working on the DSL let me know. I don't know the location but obviously a separate phone jack is the easiest. Let me know. If this helps you fix it you can rate this as fixed. If you are just going to rate this as helpful I'd rather you please not rate it and just add a comment and say thanks for the info.
If you need more help just add a comment and I'll be glad to assist you further. Thanks.

Internet connection not working

I have ATT DSL too.

Mine came with a Seimens SpeedStream 4100 ethernet ADSL modem. Did yours?
If not what is the manufacturer and model of the unit ATT sent?

Is it hooked up and working? If so continue.

IF you have a Seimens SpeedStream 4100 --

It has 3 connection on the back
one for power
one for a phone line (gray in my case)
with a separate gray cable
this is connected to the non phone side of a splitter
one for an ethernet (yellow in my case)
with a separete yellow cable
this may be loose to connect to your computer OR
connected to another device
IF connected to another device what is the manufacturers name and model for that device.

If ATT supplied a device other than a Seimens SpeedStream 4100

Is there anything other than a power adapter and a phone line attached to that unit now?
What is the manufacturers name and model for that device.

In terms of your ATT DSL service

How many devices do you intend to connect? Computers, game consoles, etc
How many connected by wire, if you know?
How many connected by wireless, if you know?

To you know if your DV4000 computer

has an ethernet connector?
has a wireless network adapter built-in?
IF not can can you look on the label on the bottom of your computer and tell me the full model number is. Please use this Model Link to help figure that out.

Do you have any devices such as a router, wireless router, wireless access point either already connected or to connect to your ATT DSL service?
Please identify the manufacturers name and model number for each device and whether or not it is connected and working.

With all the above I will know where to begin in the process of attaching your new computer to your ATT DSL service. Please add a comment to this issue with the necessary information -- I know it will be long. However you are the hands and eyes of this team and my questions are to get you to tell me things I would know if I was present and installing these devices.

2701HG-B

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.
