I can always access unleashed.ruckuswireless.com on my computer over WiFi, but my phone says "this site can't be reached, server IP address could not be found.... ERR_NAME_NOT_RESOLVED. So, why is that? I even manually set my phone DNS to the router ...
As if not using a firewall is an option? Gateway mode doesn't have a firewall as far as I can tell, so that would not be a good idea to not have some firewall before an Unleashed Gateway AP.
Oddly enough, I used a different browser, and it worked. Got that idea from this page: https://support.ruckuswireless.com/articles/000001909. Apparently the browser cache keeps it from passing the credentials to the AP.
