To fix the extender setup troubles, consider all the below solution tips. 

Improve Software Of Extender 

To get the latest version file of the extender, go to the Wavlink web management page. After that, tap on the advanced settings option and then hit on the software upgrade option. Later, install it on your computer. In the end, restart the Wavlink device to complete the software upgrade process. 

Place Extender At Half-way Location 

The central location of your workstation is best to fix the extender issue. By doing this you enjoy fast internet speed at all the directions off the office and house. But make sure while doing this process that metal appliances are not located near that. Metal appliances absorb all the WiFi signals that come from the Wavlink extender. 

Reset Wavlink Repeater 

At the back or bottom of the Wavlink device, you see the reset button. Now, press that button with the help of a clip for 10 seconds. By doing this all LEDs of the Wavlink repeater will be turned off. Thus all off LEDs define that the device is completely reset. 

Now, you will need to do the login and installation process again by visiting the 192.168.10.1 WiFi repeater setup window and considering all the directions.
