Thread:Project:Support desk/Setting up mediawiki

I'm new to setting up wikis and I am running into an issue I hope someone can shed some light on...

I installed MediaWiki on Ubuntu 12.10 and can access it fine with localhost\mywikihere

However, when I try browsing to that machines IP on my local network from my laptop it will not work says page not found. If I add http:// in front it loads the page, but it loses all formatting and looks just like text done the side of the webpage. What am I missing? Any and all help is greatly appreciated.
