If the Wavlink web portal starts showing an error like wifi.wavlink.com not working, you can take several solutions to complete the Wavlink ax1800 setup . Before anything else, you can opt for another address which is the IP address of Wavlink to get there. This is an alternative address to the web address that can also give access to the setup window. But, if this also shows an error, then we recommend you use other methods to get rid of this error. Check that your device is actually connected to the official network or not and also verify if there is a strong connection. Later, you can use another device and a different web browser to reach there. But, while reaching there this time, make sure to use a compatible device and insert the login credentials in the right way.
