When I installed Gotham 13.0. several days ago. I do not have internet only local network. XBMC found my router when I was installing, but I could not pass that screen for it was unable to connect to the internet. Now I am installed I have downloaded Add-ons and installed some of them via the zip file method. I set the web-interface and the network group to my network group name from workgroup to RoseySoft. In the summary I have no IP address or gateway, I can not seem to find where to manually make these entries. I have locked my self in my room for the past 17 hours and searched forum for many hours and can not seem to find the answer. I need to be able to access XBMC from three other PCs in the house. Thanks to anyone who can help me over this hurdle.
