Cannot connect to xfinitywifi hotspots

I have tried several times to connect to an xfinitywifi hotspot and each time to no avail.  We have one here on our own gateway and cannot even connect to that one as a test case.

 

I can direct my android device to connect to the xfinitywifi SSID just fine and it does so.  Launching the browser never redirects to a sign in page and all web pages are just not available.

 

I have tried manually going to https:\\wifi.comcast.com , that just gives useless information about comcast wifi.  

Tried manually going to https://comcast.optimumwifi.com and it never connects.

 

How do I sign in and use xfinitywifi hotspots?

Re: Cannot connect to xfinitywifi hotspots

Hi jcthorne. To connect to xfinity wifi: 

  • Comcast XFINITY Internet subscribers log in with their @Comcast.net email user name and password.
  • Comcast Business Internet subscribers log in with their @comcastbiz.net email usesrname and password  or @yourdomain.com (hosted by Comcast) email username and password associated with their Comcast Business Account.      

This Link provides additional information on connecting to xfinity wifi thru your gateway. 

 

Thank You

Re: Cannot connect to xfinitywifi hotspots

I understand what username and password to use, the problem is that when I connect to an xfinitywifi hotspot, and then open the browser, it is NOT directed to a signin page.  Just get a no network connection when trying a page.  I need the url for the signin page so I can enter it manually.  Or fix the redirect so it works in current versions of android.

Re: Cannot connect to xfinitywifi hotspots

Any chance I can get an answer to the original question?

 

"What is the URL of the sign in site for xfinitywifi?"

 

The help page referred to does not answer the question.  Only says the browser will be redirected the the sign in page.  Its not and I am asking for the URL of the sign in page so I can get there until such time that the redirect can be fixed.  I am using Chrome under Android 4.4.4

 

Thanks,

Re: Cannot connect to xfinitywifi hotspots

I've never tried to do it from android but I have no problems with windows 7 and Internet Explorer 11 and I've connected to several of these hotspots - all of which I'm 100% positive their owners are completely unaware exist.

 

Please read up about Network Awareness:

 

http://blog.superuser.com/2011/05/16/windows-7-network-awareness/

 

When the http call to ncsi happens, the wifi hotspot intercepts that and returns some magic - I don't know what - that causes Windows to popup the message "you may be required to do further authentication" then it throws up the website for the Comcast login authentication.

 

That URL may change, so I don't think there's any point in trying to bookmark it.

 

Once you login then the wifi hotspot allows you to start doing your thing.

 

There have been MANY reports of antivirus software interfering with the http call to ncsi.  And unless the wifi hotspot sees that, it isn't going to open up.

 

Try connecting again with antivirus uninstalled and see if it works.

Re: Cannot connect to xfinitywifi hotspots

I believe the "magic" you refer to which is 'supposed' to redirect to Comcast Login page is what is not working or is breaking down somewhere or in someway - (both for me on a Windows 7 Pro Laptop) as well as for the frustrated user who started this thread. I am not sure if it's an OS error caused by Windows or potentially some recent Windows update or if it's a routing (re-routing) issue causing the lack of follow through visavie the aformentioned 'magic'.  As nearly as I can tell there is a malfunction related to routing (DNS) as the error I get when trying to initiate a login by opening a browser (I try Chrome and IE - neither works) both end up on a default page identifying a problem with DNS like [DNS_PROBE_FINISHED_NO_INTERNET]

Re: Cannot connect to xfinitywifi hotspots

Actually it's simpler than that.  After connecting to one of these hotspots, open a browser and try accessing a regular NON-HTTPS website that  you DO NOT HAVE IN YOUR DNS CACHE.   If you have https://www.google.com as your homepage (or any other https: as your homepage) it will fail.  Or if you try accessing non-https (like http://www.google.com) which immediately redirects you to the https://www.google.com, then it will fail also.

 

The key is making a DNS query with the web browser to a non-https site that you do not have cached.   If you already have the IP address of the site cached - it will fail.

 

The hotspot must get a DNS query for a non-https site from you, it will then return the IP of the magic website that you must login to to turn on the outside access.  When your browser attempts to access your page it's redirected to the Comcast login page.
