proceed according and fix it. However yi\ou must read the diode LED for diagnose. God bless you

Green is not coming on as either a issue in the set's power supply or something connected to it---that simple--called shutdown.

Unless you know what you are doing likely better to take it to the shop
for an estimate of repairs.

You might want to try disconnecting everything EXCEPT the power cord. If you still get the red power light (it should stay there forever) then bring the gateway to Radio Shack or somewhere they have a 5 volt DC @ 2 amp power supply and plug it in for 5 to 10 minutes and see if the power light then stays green. If it stays green then all you need is a new power supply! If not, then the gateway is fried. Mine keeps going from a solid green power light to a flashing green power light and I can hear a relay click every 2 minutes at which time a pop-up say "ethernet line disconnected". I tried new power supply etc. to no avail! It is fried after 1.5 years! No more 2wire for me!

power unit may be out or
motherboard may be out

Go to a repair centre, some parts must be fixed/replaced.

How do I change the backlight

I needed to hold down the remote control on/off key for more than 1 second

The red light indicates that the hard drive is working (writing or reading data).  It is normal for this to flicker when the computer is running.  However, if it is on constantly or close to it, it can indicate the activity of unwanted programs (spyware or virus).  
Spyware is the most likely reason you also cannot send emails or chat online.  I would recommend bringing your computer in to a tech somewhere that can perform a virus/spyware clean for you.

hi frined

open your cpu remove the ram cleanit it put it back i hope your problem will solves

This is a Wireless Gateway not a router. Although the Actiontec website says that it uses NAT firewall like a router would.

If you do not get any green lights this usually means the wireless gateway is broken. Try plugging it into power but not the modem. Wait a few seconds. Are there any green lights?

If so, then the gateway is not configured correctly to work with your modem. You may have a smart modem. Call your ISP, for help.

If not, then it is probably a bad gateway. You can try to connect to the configuration web page that comes with the gateway. OR Power on the unit while holding down the Reset button for a minute. This will reset it to factory defaults.
