I have a similar setup and can easily connect to open wifi networks without issue. I'm trying to connect to xfinity wifi and can connect to the network but don't get the sign-in page. Any ideas?
I found the solution to my issue not being able to get the splash screen for xfinity. I set the dns manually when configuring the connection to xfinity. Once I left it blank and let DHCP set the dns settings, I was able to get the splash screen and sign-in with multiple devices.
