I go to plug everything in, my ethernet light on the modem will not light up and im not getting any connection what so ever from me ethernet port to my router, ive tryed various cat 5 cables, so i know it isnt the cable, i know it isnt the router as that is brand new and i have also bought a new cat5 to usb converter i know its not that either as it lights up when i used it on a neighbours computer!

First question - have you rebooted (unplugged) the CM during this process? Whenever you change devices on the modem you need to reboot.

Second - Is the router a 'Cable Router' - as opposed to an ADSL router? What model of router?

Third - have you plugged the CM cable into the 'WAN' port on the router - most Cable Routers will have one port for the WAN (aka upload) and four ports for the local devices.

That'll do for starters.

I think it is labelled WAN or Internet on the Linksys routers.

What LED's are lit on the front of the router? And what is on the CM? What type of CM as well?

Are you able to connect to the router's admin page? Use a browser with the address 192.168.1.1, no user name, default pass is 'admin' iirc. If you can get into the Admin pages, have a look at the status page and post the first part of the Wan/Internet IP address.
