Question about Arris SURFboard SB4200 Modem

1 Answer

Activity light is is constantly on.

Why is my activity light constantly on when my PC is not even on? It does not blink when I am using it either. It's like it is always in use even when it isn't.
I thought it could be one of my neighbors using my bandwith (Ihave a wireless router setup), but I have my security settings are on.

Ethernet light blinks continuously on my bigpond wireless. Does that mean there is a problem?

A constant blinking Ethernet activity light indicates that the computer is transmitting and/or receiving information from the internet or other network devices. It's nothing to worry about. The light may be constant only when we are setting up the modem.

What light needs to be ON on the cable modem?

The first four lights should be on. Internet / PC Link / Cable Link / Cable Activity. The "PC Link" and "Cable Activity" lights will blink. The "Internet" and "Cable Link" lights should be solid green. That's 4 lights on when all is good. I hope that this will help.

Any questions you may still have I will be glad to answer.

Flashing PC/Activity light

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

My ethernet light blinks very fast and constantly...did not use to do this--just past week

It is common for this to show activity.
The flashing on the ethernet light is simply indicating data going between the computer and the modem.
Do check for spyware and virus to be certain all is well.

No bad things found and everything works.
Do not be concerned with the blinking light.

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.....
