Hi  @Amanbir 

My only requirement is to change the field names. I want to change local user access to guest log in

username to Room no and password to Last name.

>>You can give different SSIDs to different rooms, and create a local user portal for each SSID, then configure the login user account and password accordingly.

I Changed the html code and uploaded to import custom page but it didn't work as zip file and as index.html 

>>>Please share some screenshots of when failed to upload the files so we could understand more.

If convenient, please email the zip file and the HTML code to tplink support, we can test locally. Please include this forum link in the email.
