Hi There is no DHCP in in Genesis, you use static IP address.
BUT there is fix of that in aminet
http://aminet.net/package/comm/tcp/dhcp_amitcpIf you don't want to use that, problem has a another solution.
You need to find out what kind of ip that thompson offers to your computer.
If offers private ip ie. 192.168.x.x or 10.x.x.x, where x= any number between 1-255
If you have windows machine in your network just wrote ipconfig in command prompt and press enter.
You can configure Gensis use static ip address, you just need to find out what is DHCP pool that thompson uses and conficure IP which is out of that.
