How can I protect my D-link wireless network from other using without my permission?

Question

I have a D-link wireless network without security key and other people can use it without my permission, so I want to know how to set up a security to protect my net work from other user without permission. I want to know how to set up a net work key to protect my D-link wireless network, so that other user who has no authorization to my net work can't connet to my net work.

Answer 1

1.Set up WPA passwords (WEP can be cracked easily, anyone with an internet connection can figure out how to do this in under 5 minutes, WPA has no simple way to crack, someone has to gather over 1 million packets to crack it, and even then, it's just an educated guess and not for sure).

....a) Go into your router settings, click on Wireless tab, enable
........security, pick WPA and use 9 numbers. (Reboot your
........router, and all the computers on your network, it will now
........ask them for the password you set up in your router)

2. Set up Mac Filtering (this will only allow the Mac Addresses from the wireless cards you are using on your computers, for most home networks, you don't really need to do this, but it is "extra security")

....a) This is a little more difficult, you have to find out all the MAC
....... Addresses for all of your wireless network interface cards
.......(Wireless cards)
....b) Go to each of your computers on your network, and click on
....... Start -> Run -> type in "command",
....... after you get a DOS screen type in "ipconfig /all"
....... you should now look for where it says Physical Address
....... it should say something like "00-22-WP-EC-23-3C"
....... That is your MAC address for that machine, write it down
....... (repeat that step for all of your computers you want to
....... connect to your router)
....c) Now you can go to your wireless settings in your router and
....... enable MAC address filtering, and type in the MAC
....... addresses you want to allow. Reboot your router again,
....... after all of that, and you should be good to go.

OR... (My personal favorite way)

You can leave it unsecured, and download Cane & Able, use ARP Poisoning, and sniff out all the passwords from people who are stealing your bandwidth, and then go over to your neighbors house and tell them you have their passwords and they should stop using your unsecured network... I did that... and it worked out pretty well for me.

It will give you all their myspace passwords... yahoo passwords... credit card numbers... etc, and it's all legal for you to do because its YOUR network. You can sniff out any packets you want, on YOUR network.

Answer 2

Yes with up to 5 years in prison. They would not be able to if you followed the instructions and set encryption when you set it up. You should NEVER use an unsecured wireless connection. All your transmissions can be read. This makes all your clear text user names, passwords, emails and sires visited public. And by the time you have read this a local criminal could have sent thousands of child porn or money scam emails from your connection, which will trace back to you. It would then be your door the police would break down (literally) and all your equipment they would confiscate pending investigation and prosecution.

Answer 3

You need to password protect your network. D-link will help you with this. Go to their home page and find the tech support and call. The number should also be with the user guide/info that came with the router.
