What if Dlinkap.local doesn't work? Well, If Dlinkap.local doesn't work, you can try accessing the range extender's web interface using its default IP address. Common default IP addresses for D-Link range extenders include 192.168.0.50 or 192.168.0.1. You can find the specific default IP address for your range extender in its user manual or documentation. So, worry not now!!
