I must mention that i have tried too many things to solve the problem,before i decide to post here.One of them is what you suggested before.I got the username and password from my ISP,i run the setup wizard,i established the connection,i got the success page for the device installation and opened the netgear congratulations page.So i have green Internet led and Internet access.Until here everything ok.But when i power off the router and on again,the Internet led is red and i haven't Internet access.I have to do again the installation,running the setup wizard and everything goes ok,as the first time,except that i have to do this everytime i power off and on the router.So the problem is that the router can't be reconnected automatically, after the first setup,whenever i power it off and on again.Two more things: 1. The device i talk about,is the third one i got from my local support.I mean after having exactly the same problem with the first device,took it back and got a replacement model,had the same problem,took it back and got the third one with also the same problem.Meaning i have tried three devices of the same model,but still nothing. 2. Everytime i finish the installation and setup of the device,which are successful as i mentioned,and power off and on the router again,the Internet led is red(no connection) although the settings and the values i put doing the router configuration, appear normally in all the router interface pages
