Problem!: Linksys AM200 to WAN Port of D-link Router DIR-655

Hi,

I’m having big trouble sorting out my home network, with connection from an ADSL linksys modem to the internet port of a D-Link DIR-655 Router.

I have created a visio drawing of the set up as it stands. Most likely some fundamental errors in how ive set things up caus im a bit of a novice.
