Having unwanted users on your WIFI can not only slow down your connection, it can be a security risk or even get you into legal trouble. Here are some simple steps you can take to secure your wireless network:
- Change the default administrator password. Most WIFI routers are configured via an administration web page that is protected by a username and password. The manufacturer default passwords are well-known to hackers. You should change them immediately.
- Turn on WPA2 encryption. If your router is so old that it only supports WEP, you should buy a new one. Not only will it be more secure, it will probably be faster.
- Change the default SSID or do not broadcast your SSID at all. Many routers ship with a default SSID like “Linksys”, this can be a clue to an attacker so change it to something unique like “Jane’s WIFI” and for even more security, do not broadcast your SSID at all.
- Enable MAC address filtering. Configure your router so that only the devices you key in manually can access the router.
- Do not auto-connect to open wifi networks. Change this setting on your laptop, tablet, or phone to avoid connecting to unknown networks such as free wireless hotspot or your neighbor’s wifi.
- Assign Static IP Addresses to Devices. If you disable DHCP an attacker will have a harder time obtaining a valid IP address for your network
- Enable firewalls on each computer and the router.
- Position your wireless router safely. place the router near the center of your home or office rather than near the perimeter to minimize signal leakage.
