Hi all apologies for the newbie question =) I'm having problems setting up my BEFSR41 EtherFast 4 port DSL/Cable Router with my ADSL modem/router. I've searched Google and these forums and can't find a solution. My ADSL modem is a BT Voyager 205 modem/router that gets a Dynamic IP address. I've connected the router, PC and modem all as it should be then tried running the wizard to install it. The wizard gets to a stage where it says "Your ISP uses DHCP please type the host and domain name here." I leave these default (not sure what to put and don't think my ISP will give me the details anyway since they want you to use only their products) it then its says "Configuring Router" which completes, it then goes to "Testing your internet connection" which always fails. I've tried doing the set-up manually in various ways i.e. Networking --> Local Area Network --> Properties --> TCP/IP changing to use this IP address entering 192.168.1.100, default subnet, and 192.168.1.1 as the gateway. Still no luck. So my question is how do I set up my router with my modem and my Dynamic IP? I used to have a static IP in a previous address and all I did for this was run the wizard, make the connections and it picked it up straight away. Am I having probs because my ADSL modem is a Modem/Router? Do I need a cross over cable to go to the WAN port of my router? My ADSL modem connects to the net fine, it just won't go through the router =( Any help appreciated as this is a frustrating problem and keeping my other PC's offline!
