Hi guys and girls, This question is not related to photography in the slightest but I've searched everywhere on the net and I can't find an answer. I want to set up a Wi Fi network in my appartment here because my roommate has just bought a laptop and will be wanting to use the broadband access as well. Currently just have a cord trailing along the ground to my bedroom because i'm the only one who uses it. So he went off to look at modems and educate himself on them a bit and he came back saying we'll need to buy some sort of 'key' to stick on the modem so it makes it a secure connection and people won't be leeching off our connex. Apparently it's an actual peice of hardware that you stick on either the modem or the computer (i can't remember which). Is this true? I thought we'd just have to set up some sort of VPN thing or a WEP, which is just a software thing. Like you access the little computer in the modem and tell it which computers can access the modem. Well does anyone have any idea of what I'm talking about? I really want to make the network secure because well it's really high density where I live and I don't want anyone stealing my bank details!
