Why do my Ethernet and Internet light keep blinking?

No because dsl light should be solid green light. You need to contact your ISP to check if there is a problem on the network.

Hello kb_gimper,

The power light and all other lights blink when the ZyXel P-600 is initializing. The ethernet, dsl and internet lights blink when data transfer is detected. The lights are from left to right:
* Power Light
* Ethernet Light
* DSL Light
* Internet Light

Serveral soultions to try and they are at no cost to you. First, try re-booting the modem. Your modem stores cache just like a computer does, and it can build up on you. I myself unplug mine about once a week.. Two, in the control panel under Internet Opetion under browser history click on delete and confirm the delete, this will delete your temp. files. You might have exceeded the amount of cache allowed by windows. Finally make certain that you have ipx, and spx protocol installed on your comuter. If this doesn't help, I would get a new modem from your isp, more than likely it is bad. I know verizon modem are good for maximum of 2 years and average 1 year. I would recommend westell 6100 G moem and get a wireless router to go with.

I think the light that blinks is the light that shows when you have a connection established to your ISP. Not sure if you have cable or ADSL but if the light is blinking then the router is Synchronising with the line card at the ISP/exchange end. If it continues to blink then no sync is occurring. If ADSL replace the microfilter and check that any devices atached to that line also have a microfilter between them and the socket. ALso try replace the phone cable to the microfilter to the socket. Finally you can see wether sync has occurred by looking in the log on the router
Hope this helps

whether the light on the back side ot ethernet connector is blinking

The ethernet light should not blink at all. The first thing to try is a new ethernet cable. If the problem still persists, then you need to check with your internet provider.

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.....

if your internet light on the modem is blinking or flashing, then you do not need to worry. the Ethernet light and the internnet light on the modem will always blink, but the dsl and the power lights shud not blink...

It's completely modem's problem, every modem has internal chip that's where it's store the configuration i think it is chip that is malfunctioning, change modem this problem will solve

Make sure you have internet. The ethernet light is blinking because what ever u have plugged into it is talking to the modem. The modem will then take that request and ask for it on the DSL/internet line. Make sure the DSL light is steady on and the internet light is on or flashing with activity.
