Put tinfoil over your splice connectors and filters as they leak signals that totally confuse your modem. Never leave any bare wires, I tinfoil the entire modem to prevent the neighbors from hacking me. I don't use wireless, only CAT5 ethernet cable.
With the DSL light always flashing, it means that either the ADSL signal (synchronization) does not reach your modem, or your modem cannot 'read' the signal.
You need to determine if the problem is from one of the following places :
outside of your house (your land line or ISP equipment) or from the modem;
your telephone-cable inside your house or
one of your equipment;
Try the following manipulations to determine from where the default comes :
Determine if the problem is in your house or on the land line
Unplug each and every equipment which is connected to your telephonic installation (Fax, phones, answering machines etc);
Using the shortest telephone cable (RJ11) you possess, plug only your modem to the main telephone jack of your house.
If the DSL LED still flashes continuously, the problem is somewhere between your ISP's equipment and your house. You should call them and expose the situation. At this stage, you can't do much else.
Determine if the problem is in your house installation If the DSL LED lights up when it is plugged to the main telephone jack, then it is either one of your equipment which is at fault, or the house installation. To pinpoint the problem, do the following :
With all the other equipment still unplugged, try the modem on all the other telephone jacks you have around the house.
If the DSL flashes continuously on one of the jacks, you will have found the source of your miseries. Depending on your ISP's terms and conditions, you will either have to call them of call for the services of a third-party technician to solve the problem.
If the DSL lights up correctly on all the telephone jacks, then your house telephone installation is good. Proceed to the next series of tests.
Determine which equipment is at fault
Plus your modem to one telephone jack and wait for the DSL line to light solid.
Use a splitter (ADSL filter) to plug the equipments you possess (telephone, fax etc) one by one. Verify each time if the DSL LED is still lit or flashes continuously.
If one of the equipment causes the DSL LED to flash, it is that equipment which causes your problem.
If every equipment causes the DSL LED to flash, the it is the splitter (ADSL filter) which is causing the problem. You can confirm this hypothesis by testing each and every ADSL filter you have in your possession.
Replace any faulty equipment and you should have eliminated the problem.
If nothing of this solves your problem, you won't have any choice but call you ISP. Don't hesitate to tell them all tests you will have done.
May I also make some recommendations :
Use a power surge protector (not a UPS though) to plug your modem to the electric outlet BUT plug it directly to the telephone jack;
Make sure your modem is plugged in as far as possible from UPS, television, etc.;
If possible, don't plug the modem in the same electric outlet as other equipments;
Don't use any telephone extension cable to plug your modem to the telephone jack.
Hope this helps you. Let me know what happens next.
did you install all the filters on all of your phone jacks?
If so then power cycle the modem "unplug it from the ac for 2-3 minutes". Try again
If still no luck open a trouble ticket with att and tell them its not connecting on the DSL side..
DSL light blinking green/red indicates you do not have a solid connection to your DSL signal. Typically this can be anything from the connections at your home all the way to the connections with your ISP. As I do tech support for this model of 2wire modem all day long here is what I would tell you to do if you were calling me:
Are you using the proper length of phone cord (15ft or less): people sometimes have a longer phone cord in use and while it MAY work for a while outside conditions will effect the DSL signal enough that it no longer cuts the mustard. The longer the phone cord the more resistance a signal has in reaching the modem.
Filters: Typically the 2wire modem comes with 3 1-way filters and a single 2-way filter. Often people put the wrong filter on the modem, which doesn't even require one, or they put the correct filter (2-way filter) but hook it up to the wrong end (that is to say it should be connected to the DSL side of the filter). All other devices in the house such as phones, fax machines, Tivos, DVRs, Sat TVs, and monitored alarm systems (AKA anything ELSE connecting to/using the phone system) should be on filters.
Phone service: Do you have phone service? Do you have a dial tone or static? If so all problems with phone service will effect your DSL service as that is how the DSL service is piped into your home...that is to say through the phone line. Do not contact your ISP for this problem as it is a phone line problem creating your internet problem.
Phone jack location: Have you tried moving the modem, it's power cord, and proper length phone cord to another jack? Granted the argument that "it worked yesterday, so it should work today" is a strong one but sometimes putting the modem on another jack JUST to test out any potential wiring problems is a helpful one and could save you a lot of frustration. If one jack gives you red/green DSL lights and the other gives you solid green...that should speak for itself.
ISP provider: IS your service turned on? It may be a bit...hmmm...how shall we say....obvious but if your service has been turned off, or not even turned on yet, then that would be why. In addition, if the above does not help in determining what the problem is, a technician may need to be dispatched to determine where the fault lies. Sometimes it's the box down the road and sometimes it's a few miles away.
Does the DSL light come on at all when the modem is powered up?? If not, then it looks like the modem is bad.
When the modem is first powered on, all of the lights should come on and then go off after a few seconds. The power light should then begin to blink while the modem does a self test. Once that is done, the DSL light should come on and begin to flash red. If it senses a DSL connection, it will change to flash green until it has established a DSL connection. If it does not detect a DSL connection, it will continue to flash red. If the light does not flash at all or if the power light continues to flash after a minute or so, then the modem is most likely bad.
I had the same issues with SaskTel in Canada, with the same router. It was a downstream line issue. Actually, I had the problem twice with 2 separate causes. I'd check the continuity of the lines from the punchblock (where the service enters the house) to the wall panel that you are plugging the router into. There may be a bad pairing somewhere in the wall from corroded wires, rodent damage, heat etc... and simply swapping the pairs at the block and the wall may fix the problem. That being said, both fixes from SaskTel came at the local junction box, once from a tech bumping one of my lines off the block and another from a second high-bandwidth line being connected into the same pairing as mine on the main line.
So, unfortunately, if its not in the wall...you'll be pulling teeth with AT&T for a while.
The DSL light flashing on the modem is natural for it means the device is synchronizing. But if the DSL light continues to flash, you have to wait a while before connecting, it shouldn't take more than a minute. If it does, you may need to contact your service provider because that is uncommon whether there is active Internet connection or none.
if all the lights on the modem are Green then it means there's no prob
with the hardware. just make sure that you're going to use the right
WEP key or wireless password. the network name is 2wirexxx, the X is
the the last 3 numbers of the SN which can be found on the bottom of
your 2wire 2701HG-B.make sure that your wireless switch is also turned
on of course. the wireless light on the modem will lit if it is
i think when you purchased the 2wire modem it usually comes along with 3 sets of single port dsl line filters, try out those other filters see which one works. if the local network light doesn't come on, (are you using 2wire 1000 series?), check the network adapters in your computer, this usually happens when you are using lower versions of OS. try the power outlet in the kitchen / bathroom, if power light doesn't come on, push the reset button for 30 secs. if power light is still off or red, then you may need to replace the modem (check if it's still under warranty, if not you will need to buy a new one.) also you should be using the same power adapter that came with the modem, check the specs. sometimes if the modem is more or less than 3 years old, they could get defective especially if it's often affected by sudden power surges.
