Furthermore, D-Link’s update policy is finite; once the product reaches end-of-life (EOL), no further security patches are released, leaving the device vulnerable. Finally, the GUI, while simple, can feel sluggish due to the limited processing power of the embedded MIPS CPU and the overhead of the web server (typically httpd ).
