There are 4 lights on the router power,status,ADSL and ethernet. Ethernet is the light which is causing the problem. Most of the times when I turn the router on then the ethernet light does not turn on.Even pushing the Ethernet cable at the back of the router and at the back of the CPU do not seem to help. Turning the router off and then on again does not solve the problem. What solves the problem is restarting. As soon as the computer is finished with booting the light turns on. And now even turning the router off and then on again does not cause the problem.The problem is completely solved untill the computer is shut down and then the same problem reoccurs. That is basically to turn the ethernet light on and connect to the net I have to restart my computer once. But each time before restarting I tend to push the ethernet cable behnd the router. So what is the problem is it with the router or the ethernet cable or with any other thing?
