Check your WiFi network which devices are connected and apply some additional setting

If you did read this post, you probably start to worried about how secure it is of your WiFi network. But if you did follow the tutorial in this post, it will help you to prevent unauthorise access from those people.

But if you want to find out what devices are connect to your network, follow these steps (This is based on DLink DI-524 WiFi router):

1. just goto your admin panel through your web browser, something like (192.168.0.1 or 192.168.0.2 or 192.168.1.1). Login with your password.

2. Goto “Status” > “Wireless”:

Here will show you how many devices are connected to your WiFi router/AP/modem. Please note it will only show MAC Address. If you not sure where to see this MAC address. It is an “Ethernet ID” actually, from Mac, you can goto “System Preference” > “Network” > “Advance” > “Ethernet” to find out. PC i forgot where.

Another place to find out:

You can also read that from:

Goto your WiFi router admin panel again, goto “DHCP” under “Home” tab:

Under this “Dynamic DHCP Clients List” will show you all the connected WiFi device with MAC Address, IP address and Name (Usually are the PC/Mac device name that you setup at the first time when you setup your pc/mac)

Because i did setup a static DHCP, so my devices are under “Static DHCP Clients list” * Basically it is a setting that allow you to set a fixed IP to your device, everytime they connected to your WiFi router/AP/modem.

Limit your available IP range (Optional to setup)

Limited your available DHCP IP will help you to avoid to many other devices connect to your WiFi AP/Router/Modem. Because WiFi router will assign one IP to your device. So if you only have less than 5 WiFi device at home/office. Then limit your DHCP IP to 5 or extra 2 for guest to use, which is total 7. To do that, simply enter the “Starting IP Address” under this “DHCP” page to the number you want the IP to start. For example “100″:

And “Ending IP Address”, put “106″. Lease Time, leave it as 1 Week, or if you prefer 1 Day just change it then.

So your available IP from your WiFi router/AP/Modem will be:

192.168.0.100
192.168.0.101
192.168.0.102
192.168.0.103
192.168.0.104
192.168.0.105
192.168.0.106

When all these IP are fully used by your WiFi device, no matter other devices are trying to connect, even they have the WiFi password, they won’t be able to connect.

This is not really protected your WiFi router, it just limited the available IP range. Please follow this tutorial if you really want to secure your WiFi.
