To optimize the router’s performance after the Wavlink ac1300 setup you need to access the wireless advanced settings. That will provide bandwidth channels, frequency bands, and other options for your router. But, to reach there you will also need to do the Wavlink router login first. Which you can do through any web browser or the Wavlink WiFi app on your networked device. So, go to the web browser and search for the router’s web or IP address if you chose the first method. But, if you select the app method, then launch the WiFi smart app on your smartphone. Do log in to the router first by using the default credentials. If you have updated them earlier then use those ones. Now, you can use the advanced settings of the router as you desire.
