After the Wavlink extender is perfectly set up, it is necessary to verify whether you are getting the expected internet speed. As this extender works to boost the existing router’s signals, the speed must significantly improve. So, to check that, run a speed test on any site on the web browser and check the upload and download speed of the network. Later, you can connect a range of devices to its network to learn more about the extender’s working. Also, you must carry out a large file transfer process on your networked device. Like transferring your PC file to another device or streaming online 4k HD video on your smartphone. If you find the network slow working or an error like the Wavlink extender not working, unplug it to perform a reboot process. Later, check the extender’s working again.
