Sometimes people use their neighbor's wifi signals without their knowledge. But I thought when you set up a wifi in your home, there is a name and password.

Does this mean that sometimes people's wifi doesn't have a name and password, which is why the neighbors can access it?

By default, there is no encryption. If someone just plugs in their wireless modem or router, and doesn't set it up, and use it as-is, there isn't anything stopping anyone from using it.

Some manufacturers have guided setups that the user can use so that they can set whether or not they want to broadcast the SSID, change username and password of the router, what type of encryption, what channel to use, the name of the network, etc.

To prevent someone stealing your signal ALWAYS have your signal password protected.

No password protection and you're giving a free ride to some scum who won't pay their own way.

Not only that, but if they get a hold of your wireless network, they can sniff your packets out and grab anything from CC info to what type of dog food your dog likes.

Also, you can never fully STOP a hacker from gaining access to your network (other than physically turning the router/modem off). You can help slow them down by putting encryption and strong passwords on your router, and stopping broadcast of SSID. Its more of a deterrent than a safety net......if they see your network, which is encrypted and secured, and they see your neighbors network that doesn't have any protection.....it'll be much easier to get into theirs, rather than yours

By the way, this is not to scare you, just some information I leave my router on 24/7, and I don't fear that my info might be sniffed. How many times a week do you hand over your credit card to a waiter/waitress? Who's to say they won't jot down that number while they're back there charging you for your dinner

If your WiFi is not secured, and someone that connects does something illegal, such as downloading copyrighted material, downloads or uploads kiddy porn, harasses or bullies someone on the internet, sends threatening messages or emails to an elected official, and more

Guess what, it looks just like you did it, as it links directly back to YOUR account and public IP address, which is easily obtained by law enforcement agencies.

I thought that when you first install a wifi router in your home, you are required to run through a setup before wi fi will work, is that right?

Can you skip the setup stuff and the wifi will work any way? I've never done it.

Very difficult to capture a CC by 'sniffing' traffic, as the browser will be using SSL or TSL encryption to transmit those. But the could easily dig through the files on your computer and find that information.

I also have my router set so it does not broadcast. You need to know the router name/address along with a password.

It's fairly common nowadays that they require some sort of setup. However, many will work straight out of the box.

You'd be suprised. There are tons of sites that send CC info in clear text.....not only talking about banks and paypal here. Obviously it's pretty rare that some dude is going to stumble upon your wifi connection, break in and start searching around at the same time that you send that info to the server.

off topic a bit.......
To guard against CC theft I check my info on our banks site everyday before I shut off my computer at bed time to look for charges we didn't make. If I find any,I did find one and stopped it, I notify my bank next morning.

Doing this takes about 10 min at night and is worth the time to me.
