Hello,

you have two options:

1. Connect a LAN cable from the INTERNET port of the router to your computer. Set your computer a static IP like 192.168.1.2, netmask 255.255.255.0 . The router should be available at 192.168.1.20

2. Connect a LAN cable from the LAN port of the router to the computer, be sure that no other cables are connected to the internet port. Set your computer to get an IP from the router via DHCP. You should get an IP from the router like 192.168.20.47 . The router should be available at 192.168.20.1 (if you cannot connect you have to wait).

Please let me know the results.
