Wireless Security Tips

By Scott Sekinger



Keeping your home or business wireless network is very important in today’s world. If you do no secure your wireless network then it is available for anyone to use. Every day you hear about companies being hacked and information getting stolen.. The tips in this article are meant to help you secure your home Wireless network. Disclaimer due to technology changes all of the time some of the information could be out dated about time you read this.

Use Encryption on Your Network

It is very important to use encryption on your home Wireless network. Without encryption your Wireless network is open for any one use. In case you do not know encryption scrambles your information so only certain people or devices can read the information. For additional information on encryption head to over to When it comes to wireless security there are 3 different types of encryption:

  1. WEP- WEP (Wired Equivalent Privacy) is the old of the three and is no longer recommended. It was supposed to provide the same level of security as if you wired in. It was not as good as the creators thought it would be, because it has many security flaws, which makes it easy to crack.

  2. WPA – WPA (Wi-Fi Protected Access) replaced WE provides more security, because gives away to check to see if an attacker captured and changed the information that comes in and out your network. The key used to allow a device to access the network is longer and more secure than the one used for WEP.

  3. WPA2 – WPA (Wi-Fi Protected Access Version 2) is more secure the WPA, because it makes mandatory use of AES algorithms and the introduction of CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) as a replacement for TKIP (still preserved in WPA2 as a fallback system and for interoperability with WPA).

Head over to for a more detailed description of each type of encryption.

The type of encryption you use depends on what the oldest device that will access your network supports. When every possible use the best encryption that is available to you as of 1/26/2015 WPA2 is the best.

All three types of encryptions require the use of a key. You know that you are connected to a secure Wi-Fi connection when you see a pad lock by it.


Change Your Router’s SSID Name

Always change the name of your router. A lot of the routers come with a standard name like Linksys. Never use your address or anything that will people determine who the router belongs to. If it is not already some random numbers and letters change it. This makes secure, because it makes it harder to determine the type of router it is.

Disable SSID Broadcast

Turn off the SSIDS Broadcast when possible. This will make your network harder to find, which makes it more secure.

Change Your Router’s Password

Change the password on your router as soon as you can. All routers come with some standard password. The two most commonly used are admin and password.

Update Your Router’s Firmware

Keep your router’s firmware up to date. Every vender releases firmware updates to make your router more secure, fix bugs, and sometimes add new feature all the time. I highly suggest you do this as soon as you get your router, because the router has probably been sitting on the shelf for a while.

Avoid the Use of WPS

WPS (Wi-Fi Protected Setup) is a technology that is supposed to make it easier for people to secure their home network, but it could cause more problems than it is worth, and it has security flaws of its own, which could leave you open to attacker’s brute force attacks.

Configure the Firewall Settings

A router’s firewall be on by default. Go into your verify that the firewall is on. If you want to configure your router to be more secure then every router comes with a way to change the firewall settings. Be very careful when configuring the settings, because you can cause problems with your network. Some routers come with the firewall already on for you. If you afraid that you will make your network hard to use then just double to make sure that it is on. To learn more about firewall’s checkout

Before changing the settings of the firewall make note of the original, and the modifications you make. I also recommend you do an internet search on any feature you do not understand before you make the change.

Use MAC Filtering

You can use control which devices that can use the wireless network by entering the allowed devices MAC address into the list of allowed devices in the router. MAC (Media Access Control) is the physical address that is assigned to each network device defined by its manufacturer

Turn Off When Not Using

Consider turning off your router when you are not going to use for a long period of time. This will stop attackers from attacking your network while you are not there.

Determining How to Setup Your Firewall

It easy to determine how to configure your firewall by doing a search with your search engine of choice, or asking the firewall’s manufacture for a link to the manual. Most ISPs give you a modem/ router combo.

Use the computer’s own firewall software

Consider using the firewall software that comes with your OS of choice. This will provide you with extra protection if not only if something gets through the firewall that comes with the router, but also from any attack that is made from devices that are on your local network.

Using a firewall is very important to use if you are using someone else’s, because you have no control of the devices are on the network, and what the people are using the for
