Question: How to change the web portal logo on the ZD to the default one from the user customized logo
Customer Environment: ZD1100 with 25 dual band APsResolution
Resolution: In the ZD GUI , we can change the web portal logo to the user defined logo using the following option.
Configure -> Guest access -> Guest access customization.
However after changing the web portal logo to the customized one, if we intend to role back to the default one, the options are as follows.
- Upload the same default web portal logo which can be downloaded from the internet.
- Make sure that the upload file meets certain criteria in file size.
- Check with the ZD GUI under Configure -> Guest access -> Guest access customization for the file size details.
- Hard reset the ZD. So that it will go to factory default configuration.
Default web portal logo file is attached to this Knowledge Base article.
