The number of free public Wi-Fi service in Nigeria is growing rapidly. However, the securities of most of these hotspots are not guaranteed and are sometimes questionable.

Below are some essenial tips for protecting yourself and your PC while on the go:


You should disable sharing setting on your devices before logging onto a public Wi-Fi. Just to be double sure you don’t have your music library, printers or files, or even remote login from computers on your network on, double check. Windows users can check the status by opening the advanced sharing settings of the Homegroup section of the Network and Internet settings in the Control Panel. From here, you’ll be able to toggle file and printer sharing as well as network discovery,


Another secure way of surfing the internet on a public network is by using a Virtual Private Network (VPN). A VPN routes your traffic through a secure network even on public Wi-Fi, giving you all the benefits of your private network while still having the freedom of public Wi-Fi. Free VPN providers are available everywhere, just Google up one.

Firewall should be on
