    I believe that my wireless "key" has been compromised and I would like to know how to change it. Please be user friendly as I am not very technical.

    wed need to know the model of your router or access point (whatever device is providing your wifi)

    Note: If you mess up, you can always use a paperclip to push the reset button on your router for about 30 seconds. Doing so will return your router to the factory settings.

    1. Go to
    Unless you've changed it, the password to get to your router config (NOT related to your wireless key) is admin. Leave the user blank.

    2. Choose Wireless, and then Wireless Security.

    3. Set it to use WPA Personal (aka WPA-PSK) and TKIP.

    4. Get a nice strong password in a secure manner from https://grc.com/passwords The 63-character one is best.

    5. Set this as the password on your router and push the button to save your changes. For this to take effect, you may or may not need to restart your router (unplug, then plug back in) after doing this.

    6. Enter this password into each of the devices you want to connect wirelessly to your network, making sure that each device will remember the password for you. An easy way to enter the passwords in multiple devices is to put the key in a file on a disk (flash drive, etc.) and then copy and paste from that.

    Others may tell you about things like WEP, MAC address filtering, or SSID hiding, but as far as true security is concerned those are worthless. Use WPA with a strong password (very long and very random) and you will be secure.

    Thanks so much, it was all so very simple even for a non geek like me.
    Appreciate it.

    Glad to help. Also, you may want to change the passwords you use for websites, email, etc. If someone really did get into your network before, they could have easily been using freely available to software to see any data (usernames, passwords, contents, everything) that went through your network that was not already being sent over a secure connection (SSL). An example of an already secure connections would be websites using https (your browser probably shows a lock when you're on such sites). Your email password would be a particularly important password to change, because of those "forgot your password?" links.

    If you don't mind my asking, I'm sort of curious what caused you to suspect that your wireless key had been compromised.

    Thanks for the additional info. I'll change all of my passwords that way I'll feel more secure.

    Insight, my broadband supplier, emailed and called me to tell me that I was using too much bandwidth, like I was downloading way too much stuff, huge files to the point where it was affecting other Insight customers. The biggest thing I do is email and surf the net and some research, so it couldn't have been me.

    kjsnana, do you have other users of your computer at home? (friends, kids...).

    Someone may have installed a peer 2 peer application on your computer, like kazaa or bittorrent. Those applications are used to download files and allow people to access those same files. This would explain the high usage of your connection.

    Nope, there aren't any other users. I'm pretty sure that someone had figured out my key or something.
