You don't log into SL using your "wifi password".  You use your wifi password to connect to a wifi network.  If you are not able to connect to your wifi network, it's not a Second Life problem at all.

You log into SL using your Second Life user name and password.  If you can do this from one computer/home network, but not another, the problem may be with your firewall.  Most setups have two firewalls...one on your PC itself, either the Windows Firewall, or one provided by your antivirus software, and another "NAT Firewall" that's in your router.  You'll need to check both of them to see if one or both of them are blocking Second Life.  See this article:
