Android 7.1.1 Beta WiFi issues

I don't have an issue with WiFi at home, but when I'm at a hotel and there's a sign on process, the window that comes up to sign on crashes the phone and I subsequently can't connect to the wifi.
Have any of you had this problem and is there a solution for it?
I like 7.1.1 way too much to go back Btw.. I can live without the wifi but I do watch a lot of YouTube and it would be nice..
