Thanks, this makes things a little clearer. So I switch on the DHCP server and ask it to dish our a certain range of IPs. I then set IPs outside this range manually in the control panel on all the computers I want to have fixed IPs. I then find their respective MAC addresses in the router web interface and bind them to the very same IPs I've set on theses computers. Hope this is correct.

No. If you fix the IP's in their control panels, you do not need to use the Bind to MAC option. It won't do anything as, once the IP is fixed, the PC will not ask the router for an IP address. The bind IP to MAC thing is a way of fixing the IP at the router so you do not have to fix it at the PC.

Sorry I don't know. My routers have a completely different UI to yours. If you don't know, you probably have not switched them on.
