We will discuss how to access tplinkwifi.net. Most TP-Link models employ a security model that prevents the tplinkwifi.net page from being accessed if no client logs in to the management page for an extended period of time. After restarting the modem or router, the page becomes accessible again. If you determined that this was the source of the problem but find this security feature to be bothersome, you can most likely disable it by updating its firmware to the most recent version.
