Only thing to do is buy a new modem. Mine did the same after a power surge. Left it all night off and in the morning started working again.
a month later, another power surge and never started egain. Just got me a new one and called Comcast to activate it. Problem solved.
Good luck there

Check the speed and call ISP tech support to run the line test
Before calling them do a complete power cycle
Turn the modem off and the computer off and router if any
Wait for 30 seconds and turn the modem on and wait for the lights to turn solid
Once ready turn router if you have else computer
Delete the temporary internet files browsing cookies,cache memory.
If the modem turns too hot after running for an hour please replace the modem
DSL light blinking green indicates that there s no proper signal to the modem
Check the wall jack for any loose contacts
If you have any filter check them too
Isolate them and try with it
Change them if possible

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

All Lights are on...


If the Cable light does not come on and/or the Activity light doesn't turn on, there is a problem with the plant equipment and you need to contact your provider to fix it. It could be a cabling issue outside of the residence or something could be down at the plant itself. This can also happen when the temperatures rise or if there is condensation inside the cable as it causes signal loss and increased noise on the line.

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

Internet


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......
