In addition to the web and WPS methods, the app method can be used for setup. The app window will provide access to the same procedure and features which include logging in to the extender, setting it up, and changing advanced settings. Thus, if you find it difficult to set up Wavlink AC600 Extender using the above two methods, you can go with the app method. Start by getting Wavlink WiFi installed on your Android phone or iOS device from the app store. Be sure to select the latest official version of the app and launch it afterward. You can now go to the Wavlink AC600 setup portal by logging into the window by inputting the default username and password. The next step is to select the network from the available list and input the network password and click on the extend button. Congratulations, you should see the Extend Successfully message on your device screen, and you are done!
