Securing Wireless Connection
Nowadays, many of us uses a wireless connection for our internet services, since the internet connection using wireless is easy and simple for those who likes mobility of internet access. However in other condition we have to know how to securing the wireless connection as we know the wireless connection has a public coverage area which where someone will be available to access it. Now, i will try to share my experience about how to securing a wireless connection on ADSL modem which have a wireless features. I have bought a Wireless ADSL modem a couple weeks ago. In this case i have 2 computers, 1 is a Notebook and the other is PC. All of them have Wireless card installed, and i want to connect them to internet connection from my Wireless ADSL modem as an Access Point. Not only 2 computers as i have a PDA need to connect to those Access Point. So i think it’s a good reason for me to build an Access Point in my home. Let’s get start to securing our wireless connection to prevent from any unauthorized access as like as the following details:
1. Change the default of admin password of the wireless ADSL modem.
Usually the vendor of this product will setup the default password of the Wireless ADSL Router, but we must to change this password since the default password is only for temporary access when we installing the router.
2. Activate the encryption
This function is able to encrypt any traffic data connection within our wireless connection, so that anyone will not able to steal the information within our wireless connection.
3. Change the default SSID name.
An Access Point will use a unique name to identify its connection and it’s called SSID. Usually many vendors will release a default name of SSID for their wireless router product as like as Linksys’s vendor, they named their SSID product as default as “linksys”. In fact if someone have known the SSID name of an Access Point, they still can’t access to the Access Point (AP). However it’s a beginning for them to try to hack our AP. So that we have to prevent it.
4. Activate MAC Address filtering.
Each of Wireless device have a unique identification which is called “physical address” atau MAC address. An Access Point or a Router will log a MAC address of any devices which was connected to them. Whith this feature, you can decide what kind of MAC address you will allow to connect to your AP. In this case, we have 3 devices which will be connected to Access Point, 2 computers and 1 PDA. So we just need to entry 3 MAC address in our Access Point.
5. Turn Off Broadcast of SSID.
This feature is not important as we don’t want to share a wireless connection to public user, unless you want set your AP as Hotspot.
6. Set the client ip address as static.
In this case, i only have 3 clients, 2 computers and 1 PDA. So i need to setup them to have static ip address. DHCP or Dinamic ip address is not secure for me especially for wireless connection.
Well, that’s it, securing a wireless connection in my home which is have 3 clients. Hope it can help.

I cannot believe this is true!
Sometimes it’s really that simple, isn’t it? I feel a little stupid for not thinking of this myself/earlier, though.
I would have to agree with that.
