I'm having problems with the TL-WR820N.

Remote Management: Enable

HTTP Port: 8888

Web Address for Management: 192.168.7.59

 

The problem I'm having with this router is:

These router often become unresponsive after being operated for a several days (after the next 3 - 5 days). When this router becomes unresponsive, access to the router administration page / web address for management cannot work, and port forwarding also does not work. So that all devices behind the router become inaccessible.

 

All clients behind this router is an IoT device (ESP8266) which uses very little data traffic.
