It is an intelligent network that connects all things to the Internet for the purpose of exchanging information and communicating through the information sensing devices in accordance with agreed protocols. Aside the various benefits IoT provides, it also presents challenges related to security and privacy. Current research works are geared towards ensuring security and privacy in the IoT field; developing cryptography algorithms and protocols with much focus on the application and network layer of the IoT architecture. This paper presents the current state of WiFi routers as a gateway through which WiFi-connected IoT devices can communicate. It discusses security and privacy issues related to these WiFi gateways. It goes further to suggest mitigation techniques that address the security and privacy issues found in these WiFi gateways. http://pubs.sciepub.com/iscf/6/1/2/iscf-6-1-2.pdf IoT WiFi DHCP IPv4 FTP SSL SFTP SSH JSON
