To start the Wavlink AC750 setup unbox the Wavlink extender and router. Also, make sure to check all the required accessories, like an ethernet wire and power adapter, etc. Connect the Wavlink device to a power source using the adapter. Place the ethernet cable inside the router and then to the extender. But check if it is inserted properly into the WAN port. https://wifiwavlink.net/wavlink-ac750-setup/
