Windows 10: Wifi shows internet is "connected, secured" but Outlook and Teams show that they can't connect

I am using Windows 10, and since yesterday have been having a problem where the laptop suddenly thinks it can't access the internet.

Xfinity Wifi showing up in my routers available internet connections ?

I recently found that "xfinity wifi" is showing up in my available internet access list as an openly available option.
I have comcast xfinity hi speed internet as my internet provider but have never had it show up on the routers available connections list before. The home network I set up years ago has a different name.

I am puzzled why this free open network has suddenly appeared in the list. As it requires no password I think there is a possibility its use might present a security risk
Is this a new Xfinity feature??

  I was not able to work on this issue yesterday ( busy for a 90 year old). This evening I was able to take the steps that were suggested in your email.
  
  When I use “Device Manager” I click “ Network Adapters” I see “ Wifi” but not Eternet in this list. On the “Settings” I click “Wifi” which shows the “On' button.
  

I click” Show available networks”. I wanted to capture the page that is shown, but it will not show. The top line is Network ( connected) but course I have the Ethernet cable connected. Also showing Is Five “ Broadband connections” At the bottom is
“ Network and Internet settings” I hope for your continued help.
