Help! - TOTAL Newbee

Ok…so I purchased a micropoynt router and want to find 802.11 b/g/n signals that I can log onto and use in my area. I was able to get into the router through WinBox 4.5 and then round some signals from bridging the ethernet but am now stuck? How do I connect to a certain AP? How can I tell if it is encrypted? Ahhhh..I’m in way over my head…Can someone help?
