Sky Router Help! Router not working, but all green lights are on

I have a sky router (Sagemcom v.6) that when connected properly to my computer, does not work. The power, wireless, @ and ethernet port 1 lights turn on and are all solid green. However the internet does not connect. I have another 2 sky routers which both work, however I turned the DHCP server off (by accident) on one router recently and now that no longer works. I figured I probably have turned the DHCP server option off on my newer v.6 router. I can't reach the 192.168.0.1 address for the settings on the newer router and the older one which stopped working. Is there any way of turning the DHCP server option back on these two routers? I'm able to connect them to my oldest (but still working) sky router, if that is of any help? Nothing can connect (i.e iPad, iPhone, laptop etc) to the router when its connected and running (green lights on too)

Thanks for all answers and help

Added (1). I've already had the set up date a long time ago, it's due to a change in setting that was probably caused by me messing around. I just can't access the setting page (192.168.) to see what's wrong!

You have to wait for the setup date, i had the same problem, just plugin it in and the 3 lights will come up when they've activated your Sky router.
