The other day i reformatted my laptop's hard drive. When i got my driver installed for my d-link wi-fi, i looked in my network neighborhood and saw my other pc's shared folders (i didn't run any network wizards or anything). So, i set up my printer for sharing on the pc and everything was good. then, i went to the pc to see if i had access to shared folders on the laptop. no, i didn't. so, i ran network setup wizard and when it finished i could look on the laptop. but, when i went back to the laptop i couldn't see anything on the pc or use the printer. i ran the wizard on the laptop and now i'm totally screwed as i can't see anything on either computer. what makes this happen and how can i set up my network again? thanks.
