The default IP address for a NETGEAR Wi-Fi extender can vary depending on the model. However, many NETGEAR extenders use 192.168.1.250 as their default IP address. Keep in mind that the IP address may change if it’s assigned dynamically by your main router’s DHCP server. To find the exact IP address of your NETGEAR extender, you can check its settings through the www.mywifiext.net setup page or look at the list of connected devices in your main router’s settings.
