I was dual booting windows 7 and ubuntu on my desktop. I configured a tp-link wr940N router from the windows 7 desktop, and I'd use a windows 7 laptop via wifi.
I just wiped windows and installed ubuntu 12.04 on both the desktop and the laptop. No problem connecting to the internet, whether on the ubuntu desktop or the ubuntu laptop (through wifi) but the network definition is still a 'windows' network, and I'm not able to see one computer from the other. I guess the router is just doing it's thing, as if nothing changed.
What do I need to do to have a regular home network?
