You can manually adjust the IP address on the Wavlink extender setup page. The IP address is on the back of the Extender. To log in or change the IP address, go to wifi.wavlink.com. Follow the steps to complete the procedure. Enter the WiFi extender's advanced settings and ensure that the credentials are accurate. You may run the gadget quickly by selecting the 1, 6, and 11 channels. These provide continuous WiFi speed. In contrast, the new extender immediately detects 50 concurrent channels on the 5GHz frequency. So this was the brief description of wavlink. Before doing anything, keep these considerations in mind.
