Secure a Router
If you choose to set up a router or wireless access point, you are responsible for all the incoming and outgoing traffic that passes through it. Because of this, ResTek STRONGLY recommends you take steps to secure your router and allow only those people you know and trust to make use of the wireless connection.
User’s manual
Every router has different instructions for securing the router. For specific instructions for your router, see the user’s manual or help guide. Many user guides are available online:
Linksys: Select your router, then click “User Guide”
D-Link: Select your router, then click on “Product Manual”
Belkin: Select your router, click “Download”, then download your “User’s Manual”
Netgear: Select your router from the “goto product support page” box on the left, and then download the Setup Manual.
Recommended security features
Change the default administrator password/system ID (SSID)
Most routers come from the factory with the same default settings, so the passwords are easy to crack and the system ID (SSID) is usually the name of the manufacturer. To prevent others from easily accessing the Administrator features of your router, change both the administrator password, as well as the System ID of your router.
Disable SSID broadcast
You have the option to disable the broadcast of your SSID name. If you disable this option, a computer must know the specific name of your SSID in order to connect to it. This is extremely useful in securing your network.
MAC filtering
All networking devices (Ethernet cards, wireless cards) have a unique MAC address that identifies it. It is made up of a series of 10 letters and numbers. Configure your router to only allow devices with specific MAC addresses to connect to it. This will prevent any unauthorized computers from using your network.
Secure your data (WPA)
If you will be using online banking, Web4U, or other websites with important information, you will want to encrypt the wireless data being sent. Enabling WPA (Wi-Fi Protection Access) is like using a PIN number to access your bank account. The router will have a combination, and any computer who wants access to the router must have the same key configured on that device.
WEP is a similar encryption system; however, it is less secure, harder to configure, and not recommended.
