Stay Safe on Wi-Fi: Tips for Home and Public Networks

Home Wi-Fi Security

If you use Wi-Fi at home, it’s important to keep it safe. A weak network can let hackers see what you do online. They might even steal your personal information. Here are some simple ways to protect your home Wi-Fi:

• Reduce your signal range. Try to keep your Wi-Fi signal inside your home. This helps keep outsiders from finding your network.
• Hide your network. Turn off SSID broadcasting so others can’t see your Wi-Fi name when they search for networks.
• Use a strong password. Pick a password that is hard for others to guess but easy for you to remember.
• Turn on MAC address filtering. This lets only approved devices connect to your network.
• Use WPA or WPA2 security. These are stronger and more secure than older types of Wi-Fi protection.
• Avoid WEP if possible. If you must use it, set the highest level of encryption.

You can ask your Internet provider to help with setup if it seems too hard.

Public Wi-Fi Safety

Public Wi-Fi is useful. You can connect in cafes, airports, and hotels. But public networks are not always safe. Others can see your online activity. Follow these tips to stay safe when using public Wi-Fi:

• Connect to the right network. Criminals sometimes make fake networks with names like "Free Wi-Fi." Always ask the staff for the correct network name before joining.
• Use antivirus and a firewall. Make sure your security software is updated and turned on.
• Turn off auto-connect. Set your Wi-Fi to connect manually. This stops your device from joining unknown networks without asking.
• Disable sharing. Go to your network settings and turn off file and printer sharing. Also turn off public folder sharing if it's on.

• Be aware of your surroundings. Watch out for people looking at your screen. Never leave your device alone in a public place.
• Avoid sensitive activities. Don’t do online shopping or banking on public Wi-Fi. Wait until you are on a secure network.
