Xfinity WiFi fails every time

@XfinityRaul​ Thanks for the link. The information there did not fix the problem. I can't accept the your answer until the problem is solved.

We appreciate that you tried the steps at the link, @RickCunn. We want to get to the bottom of this for you. Are you able to connect to Xfinity WiFi Hotspots at any other location with a good connection or do they all do the same thing when you try to connect (no internet or slow)? 

The problem isn't slow internet, the problem is no internet. I'e tried a variety of locations around the area, including the hot spot at the xfinity store when I was there yesterday. Same problem everywhere: iPhone (or iPad) connects to hot spot but no login pops up and when I type a url in a browser I don't get the log in. BTW, I've tried Safari, Fire Fox and Chrome. Same problem when using any of the browsers.

I did discover something interesting. While connected to my home WiFi I opened a google page in Safari on my phone and logged in to my gmail account. I then logged out of google. The google page was cached on the phone Safari. I then went to settings on the phone and switched to a nearby xfinitywifi hot spot. The phone connected, and within a few seconds I got the orange "no internet". I then went back to google in Safari and presto! I could log in. But I could not go to any other url (e.g. yahoo, wikipedia, ESPN, etc). I think that is why I was able to log in to my xfinity account on my iPad this morning: I'd been there already when connected on the home WiFi and so the xfinity webpage stuff was already cached.

I think I may have solved the mystery. Under Safari settings the toggle to prevent site cross tracking was toggled on (green). I toggled it off and cleared the browser cache. Once I did that the problem seems to have resolved itself. I could connect to xfinitywifi and browse. I’ll test a little more and report back what I find.
