Question about Siemens SpeedStream Modem (4100) (SS4100)

1 Answer

No Activity Wtih Apparent Connection

As of late, when left idle for any given amount of time, my activity light stops blinking and there appears to be no active connection, though the four other lights are on and steady. I am currently downloading two large projects, approximately 35+gb in size. The connection is reestablished by turning the modem off and on again. But, I just don't get why I get the "limited or no connectivity."

Depending on where you are and where you live depends on the speed of your connection eg. if your living in the countryside and if you live in the city centre then you could have a problem connecting as many people could be trying to connect to the sme thing at once hope it helps

My at&t Motorola 3360 has every light blinking but is still working. The Power and DSL are continuously blinking red and the ethernet, internet and activity are all blinking green.


Here's the thing...if the modem is unplugged, and you press the "Reset" button, or any button, nothing will happen because the modem is UNPLUGGED.

When you plug it in again, there is usually a few minutes or so during which time the lights will blink. Eventually, when the DSL connection is established, the blinking should decrease. But, there will always be some blinking going on to indicate that data is being transmitted.

If the "Ethernet" light is blinking, then a computer that is plugged into the router is transmitting/receiving data. If the "Wireless" light is blinking, then a computer that using a wireless connection to the router is transmitting/receiving data.

If a red light blinks, then that usually means the DSL connection has been broken. When that happens, for whatever reason, the modem will automatically begin its initialization routine and will continue to do so until connection has been established. During that time, LEAVE IT ALONE.

If you uplug the device, or if you press ANY button while the device is attempting to correct itself, you can cause permanent damage.

So, you are correct. It's not a problem. I'm sure you've heard the phrase "If it's not broken, then don't fix it." There's a lot of truth to that.

I hope this helps.

When the DSL light turns red it indicates that the modem has no internet signal.
So please check if the cables are connected properly
Also ensure that there is a proper signal to your premises without any interference
This is called intermittent connection
If the DSL light turns red it indicates that there is a problem with the cables connected or the DSL line
Please check your DSL connection with ISP

There is on another reason that the modem might have gone bad.
If all the above steps are executed and if this issue still persists replace the modem

Yes. I've put a piece of tape over it, so that the blinking is less annoying.

Recieve and Send lights blinking

Are you unable to connect? The send and rcv lights should be blinking. Make sure that your link light is on and not blinking. Your link light is your connection to your ISP

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.....

The activity light is off

If your activity light is not on that usually indicates the connection to your pc isn't working. Have you checked your ethernet cable to make sure it's plugged in firmly? Also, if you're using ethernet, you may want to try reseating the network card. If you're connected to a router try bypassing it and connecting directly to the modem.

Hope this helps!
