Although the Wavlink extender works to extend the existing internet signals covering the WiFi dead spots. However, to get the maximized performance from the network, you must check the network’s advanced settings and change them. But, first, verify the current performance of the extender whether that is working optimally or not. Run some online speed tests and check the uploading and downloading speed. Further, transfer some bigger files from your networked PC and keep checking the internet speed that the extender is providing. Apart from that, verify the extender’s LED panel and make sure the light is showing an ideal sign. But, in some cases, if there is an issue like the wavlink extender not working, then examine the entire network. If the settings are not changed for a long time, then make some updation in them from the web interface. Lastly, you can see the latest firmware update of your extender and update the file if there is a new version available.
