When green light is blinking green in back of the modem and modem does not work what does that mean

only IPS can sure that. if model reset fails
no kidding call them. like millions do per day worldwide.
the ONLINE led must glow, the manual is clear about LED
and connected is no it, online is first. on modems and in this case the modem side of router./modem.
3347w = wireless
LED DSL goes green solid but blinks as DSK trains and conn.
and
LED interenet solid green connnected. blinks for data and red = fail.
page 205 in 3000 series manual
google it read it..

online means internet, and fails for you
and means call the ISP any time the internet led goes dead or red
it is that simple. do it.

The modem cannot get a signal from your service provider. The DSL light is an indicator if your modem is communicating with the network of your service provider. DSL light should always stay solid green. Try contacting your service provider. It might also be an indication of a bad modem.

Are you hard wiring it? if so you may need to reboot your modem then start the ps3 back up. Don't unplug from the computer and connect it directly to your PS3 because the modem still has the computer's ip address and it won't recognize the PS3 until you reboot it. If it's a wireless connection, check to see that when you scan for wireless connection that the green wireless LED is blinking, meaning it's searching for a signal. If it's blinking, then try resetting the modem and the wireless router as well and give it another try. If the green light does not blink, then there might be a harware issue with your PS3. Good luck

If the internet light is red, it means that the modem cannot get an ip connection from the ISP.

If your ISP has a PPPOE connection, most likely, the PPPOE password is not correct.

To ensure your settings, access the modem through a web browser. In the address bar, type 192.168.1.1.

Default Username: admin
Default Password: password

If this doesn't work, try admin for the username and password. If still doesn't work, you will need to reset the modem. Just hold the reset button for 30 seconds. Then turn it off for 1 minute.

Try again to access the modem, under Configuration, click Edit beside My Connection. Type your ISP username and password then Save.

Hope this helps! Good luck!

no, a green light means there is a connection with the network and dns server (gateway to the internet) information is sent allow this network in bundles called packets. Each time a packet is sent the green light blinks.....sometimes when many packets are being sent in succession the light will appear solid. so i wouldnt worry, the green lights on your router and computer are normal and you should become concerned if these lights turn yellow or stop blinking completely.
Good Luck and Please Rate This Post!!!! :D

hey
red light on modem usually means modem is in bad state
in this case kindly try to do power cycle
way to power cycle
disconnect all the cables and leave the modem for 30-50secs
then try and connect power cable first
then connect the dsl and then ethernet and see if that resolves the problm,

that means the box needs to be reset if its going red like that its glitching if the reset doesn't work then something is wrong and i would get it replaced hope this helps

Take the modem and plug it into a GFCI outlet. You can find one in the bathroom or the kitchen.

If the power light comes on solid green and the dsl comes on red then the modem is good. Was it plugged into a power strip by the computer? If so, plug it straight into a wall outlet.

If the power light comes on solid red then the modem has hardware failure. I would contact your ISP and have them replace it if it is still underwarranty.

Well, I understand that the modem is SS4100, which means ther are
5lights on it being, Power, Ethernet, DSL, Internet & Activity....
Note:The trouble shooting is done according to the Light Status on the modem.
1. No matter what the proble is, the first step is to Power Cycle the modem to eliminate the static on the modem(to switch it off and back on).
2. If the Power Light is anything other than a solid green, then the modem is fried(except the fact that the adapter is plugged and working).
3. If the Power is green and Ethernet is off, then check for the LAN cable at the back 
of the computer if its connected to the modem.(It turns green if connected properly)
4. If the DSL light is anything other than solid green, then call up the ISP tech's to ask why the intenet is not working.
(make sure the DSL cable is plugged firmly onto the back of the modem and the wall jack)
5. If the Power, Ethernet and the DSL is green and the internet is not, the open up the Modem page(type 192.168.0.1 in the address bar and enter for the modem page), and cross-check for the username and the password. Save the changes and your internet is working!!!
6.  The Activity light usually blinks green and it does't have much to do with the troubleshooting.
The above are the basic troubleshooting steps.
Hope it solves your problem......
