Well if it works perfect and has no problems then no you don't need a new modem. if it is not doing so well and is messing up a lot then yes i would look into one, Other then that sounds normal for a router or ethernet to be active or none active.

You do got random programs on your pc that do connect to internet while not around or not even using or browsen the net.

Routers send and receive information all the time. If the lights don't blink, then you have a problem. If you get automatic updates from any website or if websites have tickers or changing pictures or advertisements on them, it will flash even more.

Thank you for the detailed information. Not having internet can be frustrating! If the "Online" light is not turning on, that means it is not obtaining an IP address from your internet service provider. Since the "send" and "receive" lights are blinking, this means the coaxial cable (Tv cable) is screwed in.

I would suggest finding a phone number for your internet service provider to assist you further. There may be a service outage in your general area, or there may be a localize issue. They may have to go through troubleshooting with you over the phone, so you may have to unplug the modem, and maybe even bypass the Netgear router to troubleshoot with them. If the issue cannot be resolved over the phone, they may need to send out a repair man to resolve your issue.

My old outdated emac wont connect to internet


A lot of people think its the computer when they can't connect to the internet. In reality it's most likely your Internet Service Provider (ISP)
Check the lights on the front of the Cable modem or DSL modem. The "received" light is the one you need to worry about, if it blinking it's receiving data.
If you are not seeing any blinking light you will need to call your ISP for troubleshooting.
A lot of times they do maintenance and have disconnect everyone in the area.

When i reset my modem it goes through the normal start up process but when it is trying to connect online the lights start flashing.(receive &send ) lights flash.


The light pattern you have described shows that the modem can not establish a connection to your internet service provider (ISP). This is typically do to a signal related issue. To trouble shoot the problem you will need to connect the modem directly to the main cable line where it first enters into the home. You will know when the modem establishes a connection by the top 4 lights becoming solid green. If at any point all 4 top green lights start to blink in sequence than you will need to contact your internet service provider to "unwall the modem". Remember most internet service providers require you to register new modems on there network. So if you have not all ready completed that process you will most likely not have access. If you can not get a connection from the main line than there is a issue with either the modem or the signal coming into the home and you will need to contact your internet service provider.

I hope that information above has helped is some way.
If possible please rate this solution.

Best to call up the cable company and go thru the phone prompts...you may just find that they're having trouble in your area...
They can also send a reset signal to your modem too.
Give em a call..

No connectivity; constant blinking LED lights "Receive" and "Send"


Or you didn't pay your subscription on time and the ISP disabled your cable modem to send user traffic over the cable network. When both Send and Receive lights are blinking that is a visual aid that the modem is working fine, but the ISP disabled its access to the network (unpaid bill, legal issues, etc.)

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

2Wire-3700 dsl red light blinking after a thunderstorm


Hi,

If you are att customer, you will be charged $60 only if there is problem inside your premises, otherwise they wont charge you.

Is there any phone connected with your DSL line? if so is it working? if its not working, contact customer support and tell them its not working

If the phone is working, you have to check the connections between the phone line to the modem. As the DSL light is blinking red, its the problem with line and not the modem.


Take care

Your modem is not synching. It could be a number of possibilities, and you're going to have to do some troubleshooting to narrow it down.
  • Verify that your AC, Cat 5, & ethernet cables are connected securly
  • Verify that your modem is not in "standby" mode
  • Power cycle your modem
  • Try a different cable outlet
  • Call your ISP to make sure your modem is provisioned and your service is set up for cable internet.
