Can't see the saved credentials for WiFi networks

Thanks for your reply mhalano​.

Following this logic, where should I see the credentials for the wireless router appearing? Just when connecting to the network?

1Password for Android sees the type of the field, not the purpose of the page, and will suggest fillable items of the related type. 1Password for Android can fill login items, credit card items, and identity items, but not other item types. 

For example, here's a network login page where you can see one of the sign in fields has the user_login id class, so 1Password will see it as a login field. 

I made Android forget one of my networks, and when I try to fill in the password to connect to it, it appears the button to open 1Password, but it doesn't appear the wireless router items in 1Password.

The options here would be to paste the information from your wireless router item into the login fields, or create a new login item, save your network name and password within, then search for it when prompted by 1Password for Android. 

Let us know if you have any questions, and thanks again!
