How can you keep your wireless router from
the WPA2 (Wireless Protected Access 2) encryption and other
security options provided by the product's manufacturer. Since
any encryption is inherently vulnerable, consider changing
the key periodically.
2. Change the default "Service Set Identifier" SSID
network name and turn off the feature that continually broadcasts
the SSID. While you're at it, change your router administration
account name and password.
3. Activate the MAC (Media Access Control) Address filtering
feature of your router.
4. Whether or not you connect to the Internet wirelessly,
always make sure your computer has an up-to-date operating
system with all the current patches and service packs, virus
protection, and a personal firewall (preferably a software
firewall and hardware-based router/firewall).
