Re: SpeedStream Modem DSL Light

You might want to check with your provider to make sure that they haven't changed anything.  Power cycle the modem, and even perform a hard reset if possible, usually by means of a small button on the back of the box.


Of course you could have just got a bad modem, and in that case, it's just as easy to take it back where you bought it.

I have a Speedstream 4100. When turning on the modem, it goes through the initial tests (lights,etc.), then the only lights that come on are the power light and the DSL light (steady green). The ethernet...

Your computer is not communicating with the router and modem it needs to reset to factory specs then reboot the computer,modem then router in that order.If this does not work contact your dsl provider for info as to your ip address ,gateway and reset with the provider.

The modem has green lights for power, but the DSL light either flickers green or goes to solid red.

Try power turning off once and if still remains the problem then the problem could be with internet service provider so contact them once. and if they say we are good then you need to look at internal bugs.
for that visit following website where you can find complete service manuals.

Thank you.

Constantly blinking Activity light

Well, you are very correct with the activity light blinking and the increased blinking except the fact that modem will encounter a problem in future...
The 5 different lights on your modem namely Power, Ethernet, DSL, Internet and Activity have their own indications and explanations.
1. The Activity Light indicates the amount of activity that is takin place on the computer on the Internet though the activity might blink even when you are not browsing. This can be explained by stating that the computer constantly keep sending signals  about it being connected to the internet and any other acknowledgements..

So, you've got nothing worry about unless the Power or the Ethernet or the DSL or the Internet light Blinks....
Cause they are the resultants of a fried modem(check for the adapter), faulty LAN connections, interrupted Dsl line and the account verification failure indications respectively.....

Speedstream 4100 does not work with router

you can't.
when the item name as modem/router. it means the main function is modem with added router function.
you can't connect 2 router/modem together. both need access to the internet and IPS for it function correctly.
however, you can connect 1 modem and one router.

Blinking light on the DSL modem.

Unfortunately it sounds like the modem may need to be replaced. I had the same issue. Even after doing a complete shutdown, resetting all the cables, restarting the modem and then the computer, it still did not work. After you get the modem replaced, I would suggest you get a spare, possibably from e-bay, so if this happens again, you will not be without DSL Service.

"fail: Test ADSL Line Sync" per AT&T Tech Readout

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...
