What if Dlinkap local setup 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!!
