How To: Detect and Keep a Potential WiFi Hacker Off My Network?

There is a way to detect someone within your network, you can scan your network with a scanning application like "Advanced IP Scanner", if you see an IP that is not yours or is not any of your host in your network, it may be an intruder.

You can change the security of your Wi-FI by using a strong encription like WPA and a long password. Also you can set up you router to use a banned MAC list that will prevent that the intruder enter again.

If you want to give him a little present, you have to know a little bit more about security and countermeasure and thing like that. Because may be he has a good skills to avoid your offensive, you never know who you're dealing.

Alex:

Brian's answer is correct. There are a number of tools to detect the intruder. Brian suggests Advanced IP scanner, but InSSIDER and Netstumbler will also work. Also, you can use Aircrack-ng and the airodump tool to see all the connections to your and everyone's AP.

The best security on a home AP is to use a long passphrase with WPA2, so simply change your encryption to WPA2 and a long passphrase through the AP console. In addition, you put MAC filtering on the AP that only allows your computer on the AP. It also can be configured on the console.

As for a gift, I's suggest a nice bottle of Cabernet would be appropriate.
