Wireless Security Change the wireless router’s preset username and passwordThe first step to bring in security is to change the default username / password. This will disallow a hacker from accessing the router's administrative pages. Most routers come with a preset username / password which is well documented in the router manual thus making it available for hackers to use. Change the wireless router’s preset SSIDThe next step is to change the default SSID of the wireless router. Every wireless router uses a network name also know as SSID which is usually preset by the manufacturers. Keeping the default SSID makes it easy for hackers to come in. Disable SSID BroadcastAll the wireless routers broadcast the SSID. This is to let others in the range know about it. For home use, this feature is unnecessary, and it increases the likelihood someone will try to log in to your home network. Disable this feature. The SSID name can be manually entered into your devices. Switch on encryptionAll wireless routers support some kind of encryption [WPA, WEP and many more] that scrambles messages sent over the air and ensure that they cannot be intercepted by hackers. Choose the desired encryption, WPA being the best. MAC Address filteringEvery wireless router is capable of tracking the MAC addresses for all computers/devices that connect to them. Such connections can be controlled using the MAC addresses. This will allow restricting the network to only the designated computers/devices. Switch Off DHCP, Use Static IPsWith DHCP enabled, hackers can easily obtain a valid IP addresses from your network's DHCP pool. Switch off DHCPSet a fixed private IP address range Configure each connected device to match the range Enable wireless router’s firewall Ensure that your router's firewall is turned on.
