Hi, As you say! with a cable broadband router you connect the WAN (Wide Area Network) port to the Virgin cable modem.
It looks from the reviews the Buffalo-WCR-GN router is not the easiest router to set-up, have you used the CD and Wizard to help you?
You set the DHCP so you have addresses reserved for static IP addresses, set-up your router for 192.168.11.1 to 192.168.11.25 as Static IP addresses, thenů
First DHCP Address: 192.168.11. 26
Last DHCP Address: 192.168.11.250
And then you have 192.168.11.251 to 192.168.11.255 for static IP addresses, this will give you in total 30 Static IP addresses.
Your router default IP Address: 192.168.11.1 now your router has a static IP address.
Configure the IP address of your computer Ethernet connection and the IP Address of your computer Wireless connection within the static IP address Range.
