normal boot

hello before i did a re-install of snow leopard on my mac mini 80 gb i put a sudo command i found on the net to boot into safe mode to check some things out,but every time i boot now i go into safe mode and i cannot get onto the internet as i cannot see airport except in utilities and when i do a scan it does not find my home network,can some one please tell me how i can get the mac to boot into normal mode please ?
thank you.

What was the command you entered to get into safe mode? You do know that you can always start your Mac in safe mode by pressing Shift after you hear the post chime? No need to mess with terminal and use sudo.
